YouTube Channel Latest Video Training

My YouTube Channel Latest Photography Video Training.

I’ve been busy this week adding more content to the old YouTube channel.

Adding content is really time-consuming, with recording times taking around twice the length of the final video.

Then there’s the editing, which usually takes around the same time, or a bit longer.  Then encoding and compression and uploading takes around the same again.

So yes, a 25 minute video takes A LOT more than 25 minutes to make and make live for the world to view.

This weeks video training uploads are:

This video deals with the badly overlooked topic of raw file demosaicing.

Next up is:

This video is a refreshed version of getting contrast under control in Lightroom – particularly Lightroom Classic CC.

Then we have:

This video is something of a follow-up to the previous one, where I explain the essential differences between contrast and clarity.

And finally, one from yesterday – which is me, restraining myself from embarking on a full blown ‘rant’, all about the differences between DPI (dots per inch) and PPI (pixels per inch):

Important Note

Viewing these videos is essential for the betterment of your understanding – yes it is!  And all I ask for in terms of repayment from yourselves is that you:

  1. Click the main channel subscribe button HERE https://www.youtube.com/c/AndyAstbury
  2. Give the video a ‘like’ by clicking the thumbs up!

YouTube is a funny old thing, but a substantial subscriber base and like videos will bring me closer to laying my hands on latest gear for me to review for you!

If all my blog subscribers would subscribe to my YouTube channel then my subs would more than treble – so go on, what are you waiting for.

I do like creating YouTube free content, but I do have to put food on the table, so I have to do ‘money making stuff’ as well, so I can’t afford to become a full-time YouTuber yet!  But wow, would I like to be in that position.

So that’s that – appeal over.

Watch the videos, and if you have any particular topic you would like me to do a video on, then please just let me know.  Either email me, or you can post in the comments below – no comment goes live here unless I approve it, so if you have a request but don’t want anyone else to see it, then just say.

Monitor Calibration Update

Monitor Calibration Update

Okay, so I no longer NEED a new monitor, because I’ve got one – and my wallet is in Leighton Hospital Intensive Care Unit on the critical list..

What have you gone for Andy?  Well if you remember, in my last post I was undecided between 24″ and 27″, Eizo or BenQ.  But I was favoring the Eizo CS2420, on the grounds of cost, both in terms of monitor and calibration tool options.

But I got offered a sweet deal on a factory-fresh Eizo CS270 by John Willis at Calumet – so I got my desire for more screen real-estate fulfilled, while keeping the costs down by not having to buy a new calibrator.

%name Monitor Calibration Update

But it still hurt to pay for it!

Monitor Calibration

There are a few things to consider when it comes to monitor calibration, and they are mainly due to the physical attributes of the monitor itself.

In my previous post I did mention one of them – the most important one – the back light type.

CCFL and WCCFL – cold cathode fluorescent lamps, or LED.

CCFL & WCCFL (wide CCFL) used to be the common type of back light, but they are now less common, being replaced by LED for added colour reproduction, improved signal response time and reduced power consumption.  Wide CCFL gave a noticeably greater colour reproduction range and slightly warmer colour temperature than CCFL – and my old monitor was fitted with WCCFL back lighting, hence I used to be able to do my monitor calibration to near 98% of AdobeRGB.

CCFL back lights have one major property – that of being ‘cool’ in colour, and LEDs commonly exhibit a slightly ‘warmer’ colour temperature.

But there’s LEDs – and there’s LEDs, and some are cooler than others, some are of fixed output and others are of a variable output.

The colour temperature of the backlighting gives the monitor a ‘native white point’.

The ‘brightness’ of the backlight is really the only true variable on a standard type of LCD display, and the inter-relationship between backlight brightness and colour temperature, and the size of the monitors CLUT (colour look-up table) can have a massive effect on the total number of colours that the monitor can display.

Industry-standard documentation by folk a lot cleverer than me has for years recommended the same calibration target settings as I have alluded to in previous blog posts:

White Point: D65 or 6500K

Brightness: 120 cdm² or candelas per square meter

Gamma: 2.2

Screen Shot 2017 04 02 at 13.04.25 Monitor Calibration Update

The ubiquitous ColorMunki Photo ‘standard monitor calibration’ method setup screen.

This setup for ‘standard monitor calibration’ works extremely well, and has stood me in good stead for more years than I care to add up.

As I mentioned in my previous post, standard monitor calibration refers to a standard method of calibration, which can be thought of as ‘software calibration’, and I have done many print workshops where I have used this method to calibrate Eizo ColorEdge and NEC Spectraviews with great effect.

However, these more specialised colour management monitors have the added bonus of giving you a ‘hardware monitor calbration’ option.

To carry out a hardware monitor calibration on my new CS270 ColorEdge – or indeed any ColorEdge – we need to employ the Eizo ColorNavigator.

The start screen for ColorNavigator shows us some interesting items:

colnav1 Monitor Calibration Update

The recommended brightness value is 100 cdm² – not 120.

The recommended white point is D55 not D65.

Thank God the gamma value is the same!

Once the monitor calibration profile has been done we get a result screen of the physical profile:

colnav2 Monitor Calibration Update

Now before anyone gets their knickers in a knot over the brightness value discrepancy there’s a couple of things to bare in mind:

  1. This value is always slightly arbitrary and very much dependent on working/viewing conditions.  The working environment should be somewhere between 32 and 64 lux or cdm² ambient – think Bat Cave!  The ratio of ambient to monitor output should always remain at between 32:75/80 and 64:120/140 (ish) – in other words between 1:2 and 1:3 – see earlier post here.
  2. The difference between 100 and 120 cdm² is less than 1/4 stop in camera Ev terms – so not a lot.

What struck me as odd though was the white point setting of D55 or 5500K – that’s 1000K warmer than I’m used to. (yes- warmer – don’t let that temp slider in Lightroom cloud your thinking!).

1000k Monitor Calibration UpdateAfter all, 1000k is a noticeable variation – unlike the brightness 20cdm² shift.

Here’s the funny thing though; if I ‘software calibrate’ the CS270 using the ColorMunki software with the spectro plugged into the Mac instead of the monitor, I visually get the same result using D65/120cdm² as I do ‘hardware calibrating’ at D55 and 100cdm².

The same that is, until I look at the colour spaces of the two generated ICC profiles:

profile Monitor Calibration Update

The coloured section is the ‘software calibration’ colour space, and the wire frame the ‘hardware calibrated’ Eizo custom space – click the image to view larger in a separate window.

The hardware calibration profile is somewhat larger and has a slightly better black point performance – this will allow the viewer to SEE just that little bit more tonality in the deepest of shadows, and those perennially awkward colours that sit in the Blue, Cyan, Green region.

It’s therefore quite obvious that monitor calibration via the hardware/ColorNavigator method on Eizo monitors does buy you that extra bit of visual acuity, so if you own an Eizo ColorEdge then it is the way to go for sure.

Having said that, the differences are small-ish so it’s not really worth getting terrifically evangelical over it.

But if you have the monitor then you should have the calibrator, and if said calibrator is ‘on the list’ of those supported by ColorNavigator then it’s a bit of a JDI – just do it.

You can find the list of supported calibrators here.

Eizo and their ColorNavigator are basically making a very effective ‘mash up’ of the two ISO standards 3664 and 12646 which call for D65 and D50 white points respectively.

Why did I go CHEAP ?

Well, cheaper…..

Apart from the fact that I don’t like spending money – the stuff is so bloody hard to come by – I didn’t want the top end Eizo in either 27″ or 24″.

With the ‘top end’ ColorEdge monitors you are paying for some things that I at least, have little or no use for:

  • 3D CLUT – I’m a general sort of image maker who gets a bit ‘creative’ with my processing and printing.  If I was into graphics and accurate repro of Pantone and the like, or I specialised in archival work for the V & A say, then super-accurate colour reproduction would be critical.  The advantage of the 3D CLUT is that it allows a greater variety of SUBTLY different tones and hues to be SEEN and therefore it’s easier to VISUALLY check that they are maintained when shifting an image from one colour space to another – eg softproofing for print.  I’m a wildlife and landscape photographer – I don’t NEED that facility because I don’t work in a world that requires a stringent 100% colour accuracy.
  • Built-in Calibrator – I don’t need one ‘cos I’ve already got one!
  • Built-in Self-Correction Sensor – I don’t need one of those either!

So if your photography work is like mine, then it’s worth hunting out a ‘zero hours’ CS270 if you fancy the extra screen real-estate, and you want to spend less than if buying its replacement – the CS2730.  You won’t notice the extra 5 milliseconds slower response time, and the new CS2730 eats more power – but you do get a built-in carrying handle!

 

Monitor Brightness.

Monitor Brightness & Room Lighting Levels.

I had promised myself I was going to do a video review of my latest purchase – the Lee SW150Mk2 system and Big and Little Stopper filters I’ve just spent a Kings ransom on for my Nikon 14-24mm and D800E:

D4D3598 Edit Monitor Brightness.

PURE SEX – and I’ve bloody well paid for this! My new Lee SW150 MkII filter system for the Nikon 14-24. Just look at those flashy red anodised parts – bound to make me a better photographer!

But I think that’ll have to wait while I address a question that keeps cropping up lately.  What’s the question?

Well, that’s the tricky bit because it comes in many guises. But they all boil down to “what monitor brightness or luminance level should I calibrate to?”

Monitor brightness is as critical as monitor colour when it comes to calibration.  If you look at previous articles on this blog you’ll see that I always quote the same calibration values, those being:

White Point: D65 – that figure takes care of colour.

Gamma: 2.2 – that value covers monitor contrast.

Luminance: 120 cdm2 (candelas per square meter) – that takes care of brightness.

Simple in’it….?!

However, when you’ve been around all this photography nonsense as long as I have you can overlook the possibility that people might not see things as being quite so blindingly obvious as you do.

And one of those ‘omissions on my part’ has been to do with monitor brightness settings COMBINED with working lighting levels in ‘the digital darkroom’.  So I suppose I’d better correct that failing on my part now.

What does a Monitor Profile Do for your image processing?

A correctly calibrated monitor and its .icc profile do a really simple but very mission-critical job.

If we open a new document in Photoshop and fill it with flat 255 white we need to see that it’s white.  If we hold an ND filter in front of our eye then the image won’t look white, it’ll look grey.

If we hold a blue filter in front of our eye the image will not look white – it’ll look blue.

That white image doesn’t exist ‘inside the monitor’ – it’s on our computer!  It only gets displayed on the monitor because of the graphics output device in our machine.

So, if you like, we’re on the outside looking in; and we are looking through a window on to our white image.  The colour and brightness level in our white image are correct on the inside of the system – our computer – but the viewing window or monitor might be too bright or too dark, and/or might be exhibiting a colour tint or cast.

Unless our monitor is a totally ‘clean window’ in terms of colour neutrality, then our image colour will not be displayed correctly.

And if the monitor is not running at the correct brightness then the colours and tones in our images will appear to be either too dark or too bright.  Please note the word ‘appear’…

Let’s get a bit fancy and make a greyscale in Photoshop:

Untitled 1 Monitor Brightness.

The dots represent Lab 50 to Lab 95 – the most valuable tonal range between midtone and highlight detail.

Look at the distance between Lab 50 & Lab 95 on the three greyscales above – the biggest ‘span’ is the correctly calibrated monitor.  In both the ‘too bright & contrasty’ and the ‘too dark low contrast’ calibration, that valuable tonal range is compressed.

In reality the colours and tones in, say an unprocessed RAW file on one of our hard drives, are what they are.  But if our monitor isn’t calibrated correctly, what we ‘see’ on our monitor IS NOT REALITY.

Reality is what we need – the colours and tones in our images need to be faithfully reproduced on our monitor.

And so basically a monitor profile ensures that we see our images correctly in terms of colour and brightness; it ensures that we look at our images through a clean window that displays 100% of the luminance being sent to it – not 95% and not 120% – and that all our primary colours are being displayed with 100% fidelity.

In a nutshell, on an uncalibrated monitor, an image might look like crap, when in reality it isn’t.  The shit really starts to fly when you start making adjustments in an uncalibrated workspace – what you see becomes even further removed from reality.

“My prints come out too dark Andy – why?”

Because your monitor is too bright – CALIBRATE it!

“My pics look great on my screen, but everyone on Nature Photographers Network keeps telling me they’ve got too much contrast and they need a levels adjustment.  One guy even reprocessed one – everyone thought his version was better, but frankly it looked like crap to me – why is this happening Andy?

“Because your monitor brightness is too low but your gamma is too high – CALIBRATE it!  If you want your images to look like mine then you’ve got to do ALL the things I do, not just some of ’em – do you think I do all this shit for fun??????????……………grrrrrrr….

But there’s a potential problem;  just because your monitor is calibrated to perfection, that does NOT mean that everything will be golden from this point on

Monitor Viewing Conditions

So we’re outside taking a picture on a bright sunny day, but we can’t see the image on the back of the camera because there’s too much daylight, and we have to dive under a coat with our camera to see what’s going on.

But if we review that same image on the camera in the dark then it looks epic.

Now you have all experienced that…….

The monitor on the back of your camera has a set brightness level – if we view the screen in a high level of ambient light the image looks pale, washed out and in a general state of ultra low contrast.  Turn the ambient light down and the image on the camera screen becomes more vivid and the contrast increases.

But the image hasn’t changed, and neither has the camera monitor.

What HAS changed is your PERCEPTION of the colour and luminance values contained within the image itself.

Now come on kids – join the dots will you!

It does not matter how well your monitor is calibrated, if your monitor viewing conditions are not within specification.

Just like with your camera monitor, if there is too much ambient light in your working environment then your precisely calibrated monitor brightness and gamma will fail to give you a correct visualization or ‘perception’ of your image.

And the problems don’t end there either; coloured walls and ceilings reflect that colour onto the surface of your monitor, as does that stupid luminous green shirt you’re wearing – yes, I can see you!  And if you are processing on an iMac then THAT problem just got 10 times worse because of the glossy screen!

Nope – bead-blasting your 27 inches of Apple goodness is not the answer!

Right, now comes the serious stuff, so READ, INGEST and ACT.

ISO Standard 3664:2009 is the puppy we need to work to (sort of) – you can actually go and purchase this publication HERE should you feel inclined to dump 138 CHF on 34 pages of light bedtime reading.

There are actually two ISO standards that are relevant to us as image makers; ISO 12646:2015(draft) being the other.

12646 pertains to digital image processing where screens are to be compared to prints side by side (that does not necessarily refer to ‘desktop printer prints from your Epson 3000’).

3664:2009 applies to digital image processing where screen output is INDEPENDENT of print output.

We work to this standard (for the most part) because we want to process for the web as well as for print.

If we employ a print work flow involving modern soft-proofing and otherwise keep within the bounds of 3664 then we’re pretty much on the dance-floor.

ISO 3664 sets out one or two interesting and highly critical working parameters:

Ambient Light White Point: D50 – that means that the colour temperature of the light in your editing/working environment should be 5000Kelvin (not your monitor) – and in particular this means the light FALLING ON TO YOUR MONITOR from within your room. So room décor has to be colour neutral as well as the light source.

Ambient Light Value in your Editing Area: 32 to 64 Lux or lower.  Now this is what shocks so many of you guys – lower than 32 lux is basically processing in the dark!

Ambient Light Glare Permissible: 0 – this means NO REFLECTIONS on your monitor and NO light from windows or other light sources falling directly on the monitor.

Monitor White Point – D65 (under 3664) and D50 (under 12646) – we go with D65.

Monitor Luminance – 75 to 100 cdm2 (under 3664) and 80 to 120 cdm2 (under 12646 – here we begin to deviate from 3664.

We appear to be dealing with mixed reference units, but 1 Lux = 1 cdm2 or 1 candela per square metre.

The way Monitor Brightness or Luminance relates to ambient light levels is perhaps a little counter-intuitive for some folk.  Basically the LOWER your editing area Lux value the LOWER your Monitor Brightness or luminance needs to be.

Now comes the point in the story where common sense gets mixed with experience, and the outcome can be proved by looking at displayed images and prints; aesthetics as opposed numbers.

Like all serious photographers I process my own images on a wide-gamut monitor, and I print on a wide-gamut printer.

Wide gamut monitors display pretty much 90% to100% of the AdobeRGB1998 colour space.

What we might refer to as Standard Gamut monitors display something a little larger than the sRGB colour space, which as we know is considerably smaller than AdobeRGB1998.

StandardGamutvsWideGamut Monitor Brightness.

Left is a standard gamut/sRGB monitor and right is a typical wide gamut/AdobeRGB1998 monitor – if you can call any NEC ‘typical’!

Find all the gory details about monitors on this great resource site – TFT Central.

At workshops I process on a 27 inch non-Retina iMac – this is to all intents and purposes a ‘standard gamut’ monitor.

I calibrate my monitors with a ColorMunki Photo – which is a spectrophotometer.  Spectro’s have a tendency to be slow, and slightly problematic in the very darkest tones and exhibit something of a low contrast reaction to ‘blacks’ below around Lab 6.3 (RGB 20,20,20).

If you own a ColorMunki Display or i1Dispaly you do NOT own a spectro, you own a colorimeter!  A very different beast in the way it works, but from a colour point of view they give the same results as a spectro of the same standard – plus, for the most part, they work faster.

However, from a monitor brightness standpoint, they differ from spectros in their slightly better response to those ultra-dark tones.

So from a spectrophotometer standpoint I prefer to calibrate to ISO 12646 standard of 120cdm2 and control my room lighting to around 35-40 Lux.

Just so that you understand just how ‘nit-picking’ these standards are, the difference between 80cdm2 and 120 cdm2 is just 1/2 or 1/3rd of a stop Ev in camera exposure terms, depending on which way you look at it!

However, to put this monitor brightness standard into context, my 27 inch iMac came from Apple running at 290 cdm2 – and cranked up fully it’ll thump out 340 cdm2.

Most stand-alone monitors you buy, especially those that fall under the ‘standard gamut’ banner, will all be running at massively high monitor brightness levels and will require some severe turning down in the calibration process.

You will find that most monitor tests and reviews are done with calibration to the same figures that I have quoted – D65, 120cdm2 and Gamma 2.2 – in fact this non-standard set up has become so damn common it is now ‘standard’ – despite what the ISO chaps may think.

Using these values, printing out of Lightroom for example, becomes a breeze when using printer profiles created to the ICC v2 standard as long as you ‘soft proof’ the image in a fit and proper manner – that means CAREFULLY, take your time.  The one slight shortcoming of the set up is that side by side print/monitor comparisons may look ever so slightly out of kilter because of the D65 monitor white point – 6,500K transmitted white point as opposed to a 5,000K reflective white point.  But a shielded print-viewer should bring all that back into balance if such a thing floats your boat.

But the BIG THING you need to take away from the rather long article is the LOW LUX VALUE of you editing/working area ambient illumination.

Both the ColorMunki Photo and i1Pro2 spectrophotometers will measure your ambient light, as will the ColorMunki Display and i1 Display colorimeters, to name but a few.

But if you measure your ambient light and find the device gives you a reading of more than 50-60 lux then DO NOT ask the device to profile for your ambient light; in fact I would not recommend doing this AT ALL, here’s why.

I have a main office light that is colour corrected to 5000K and it chucks out 127 Lux at the monitor.  If I select the ‘measure and calibrate to ambient’ option on the ColorMunki Photo it eventually tells me I need a monitor brightness or luminance of 80 cdm2 – the only problem is that it gives me the same figure if I drop the ambient lux value to 100.

Now that smells a tad fishy to me……..

So my advice to anyone is to remove the variables, calibrate to 120 cdm2 and work in a very subdued ambient condition of 35 to 40 Lux. I find it easier to control my low lux working ambient light levels than bugger about with over-complex calibration.

To put a final perspective on this figure there is an interesting page on the Apollo Energytech website which quotes lux levels that comply with the law for different work environments – don’t go to B&Q or Walmart to do a spot of processing, and we’re all going to end up doing hard time at Her Madges Pleasure –  law breakers that we are!

Lightroom Dehaze

 The Lightroom Dehaze Control

I’m getting a bit fed up with seeing countless folk raving about this new dehaze slider control in Lightroom, ACR etc.

dehaze Lightroom Dehaze

The control itself can be found at the bottom of the Effects panel in the Develop module in Lightroom CC 2015, and at the top of the ACR FX tab.

Yes it’s certainly useful, but I have yet to see anyone illustrating its bad points – so Uncle Andy has made a video: if you are reading this in email, click this link to watch the video http://www.wildlifeinpixels.net/blog/lightroom-dehaze/

I do tend to waffle a bit in videos so apologies for that…!

You might want to click the YouTube icon bottom right corner and watch this video at a larger size.

I’m not saying that the dehaze control in Lightroom and ACR is crap – far from it.  But I am strongly advising that you deploy it with some caution, especially when images contain small fine edge detail.

Under these circumstances, positive value dehaze control adjustments can have disastrous effects on fine detail.  You might not be aware of these ‘on screen’ but send the image to A2 print and you could be in for some tears.

I’ll be doing another video on the dehaze control shortly, showing some of the positives that I see in it.

Brilliant Supreme Lustre Ultimate Paper

Brilliant Supreme Lustre Paper Review

(26/07/2015: Important update added at end of post re: Canon Pixma Pro 1 .icc profile from the Brilliant website).

Printing an image is the final part of the creative process, and I don’t think there are many of my peers who would disagree with me on that score.

Whenever I’m teaching printing, be it a 1to1 session or a workshop group, I invariably get asked what my recommendation for a good general purpose printing paper would be – one that would suit the widest spread of image styles and subjects.

Until quite recently that recommendation was always the same – Permajet Oyster.

It’s a wide gamut paper – it reproduces a lot of colour and hue variation – that has a high level of brightness and is really easy to soft-proof to in Lightroom. And even though it’s not absolutely colour neutral, it’s natural base tint isn’t too cool to destroy the atmosphere in a hazy orange sunset seascape.

But, after months of printing and testing I have now changed my mind – and for good reason.

BSLU Brilliant Supreme Lustre Ultimate Paper

Brilliant Supreme Lustre Ultimate paper from Calumet is my new recommendation for general printing, and for anyone who wants printing with the minimum of fuss and without the hassle of trying to decide what paper to choose.

Let’s look at how the two papers stack up:

Paper Weight:

Permajet Oyster 271gsm

Brilliant Supreme Lustre Ultimate 300gsm

A heavier paper is a good thing in my book; heavier means thicker, and that means a bit more structural stability; a boon when it comes to matting and mounting, and general paper handling.

Paper Tint & Base Neutrality:

Permajet Oyster:     RGB 241,246,243

Brilliant Supreme Lustre Ultimate:     RGB 241,245,245

The above RGB values are measured using a ColorMunki Photo in spot colour picker mode, as are the L,a,b values below.

L,a,b Luminosity Value:

Permajet Oyster:     96.1

Brilliant Supreme Lustre Ultimate:     95.8

So both papers have the same red value in their ‘paper white’, but both have elevated green and blue values, and yes, green + blue = cyan!

But the green/blue ratios are different – they are skewed in the Permajet Oyster, but 1:1 in the Brilliant paper – so where does this leave us in terms of paper proofing?

The image below is a fully processed TIFF open in Lightroom and ready for soft-proofing:

BSLU2 600x375 Brilliant Supreme Lustre Ultimate Paper

Now if we load the image into the Permajet Oyster colour space – that’s all soft proofing is by the way – we can see a number of changes, all to the detriment of the image:

BSLU3 600x375 Brilliant Supreme Lustre Ultimate Paper

The image has lost luminance, the image has become slightly cooler overall but, there is a big colour ‘skew’ in the brown, reds and oranges of both the eagle and the muted background colours.

Now look at what happens when we send the image into the Brilliant Supreme Lustre Ultimate colour space:

BSLU4 600x375 Brilliant Supreme Lustre Ultimate Paper

Yes the image has lost luminance, and there is an overall colour temperature change; but the important thing is that it’s nowhere near as skewed as it was in the Permajet Oyster soft-proofing environment.

The more uniform the the colour change the easier it is to remove!

BSLU5 600x375 Brilliant Supreme Lustre Ultimate Paper

The only adjustments I’ve needed to make to put me in the middle of the right ball park are a +6 Temp and +2 Clarity – and we are pretty much there, ready to press the big “print me now” button.

The image below just serves to show the difference between the proof adjusted and unadjusted image:

BSLU6 600x375 Brilliant Supreme Lustre Ultimate Paper

But here is the same image soft-proofed to pretty much the same level, but for Permajet Oyster paper – click the image to see it at full size, just look at the number of adjustments I’ve had to do to get basically the same effect:

BSLU7 600x375 Brilliant Supreme Lustre Ultimate Paper

Couple of things – firstly, apologies for the somewhat violent image – the wife just pointed that out to me!  Secondly though, after testing various images of vastly differing colour distributions and gamuts, I consistently find I’m having to do less work in soft-proofing with the Brilliant Supreme Lustre Ultimate paper than its rival.  Though I must stress that the adjustments don’t always follow the same direction for obvious reasons..

Media Settings:

These are important.  For most printers the Oyster paper has a media setting recommendation on Epson printers ( someone once told me there were other makes that used bubbles – ewee, yuck) of Premium Gloss Photo Paper or PGPP.  But I find that PSPP (Premium Semi Gloss Photo Paper) works best on my 4800,  and I know that it’s the recommended media setting for the Epson SCP600.

See update below for Canon Pixma Pro 1 media settings and new updated .icc profile

Conclusion:

Buy a 25 sheet box A3 HERE or 50 sheet box A4 size HERE

They say time is money, so anything that saves time is a no-brainer, especially if it costs no more than its somewhat more labour-intensive alternative.

Gamut1 900x840 Brilliant Supreme Lustre Ultimate Paper

The gamut or colour spaces of the two paper ‘canned profiles’ is shown above – red plot is the Brilliant Supreme Lustre Ultimate and white is Oyster – both profiles being for the Epson 4800.  Yes, the Calumet paper gamut is slightly smaller, but in real terms and with real-world images and the relative colour-metric rendering intent I’ve not noticed any short-comings whatsoever.

I have little doubt that the gamut of the paper would be expanded further with the application of a custom profile, but that’s a whole other story.

Running at around £1 per sheet of A3 it’s no more expensive than any other top quality general printing paper, and it impresses the heck out of me with relatively neutral base tint.

So easy to print to – so buy some!

I’ll be demonstrating just how well this paper works at a series of Print Workshops for Calumet later in the year, where we’ll be using the Epson SC-P600 printer, which is the replacement for the venerable R3000.

UPDATE:

Canon Pixma Pro One .ICC Profile

If anyone has tried using the Lustre profile BriLustreCanPro1.icc that was available for download on the Brilliant website, then please STOP trying to use it – it’s an abomination and whoever produced it should be shot.

I discovered just how bad it was when I was doing a print 1to1 day and the client had a PixmaPro1 printer.  I spoke to Andy Johnson at Calumet and within a couple of days a new profile was sorted out and it works great.

Now that same new profile is available for download at the Brilliant website HERE – just click and download the zip file.  In the file you will find the new .icc profile which goes by the name of BriLustreCanonPro1_PPPL_1.icc

I got them to add the media settings acronym in the profile name – a la Permajet – so set the paper type to Photo Paper Pro Lustre when using this paper on the Pixma Pro 1.

Image Retouching

 Image Retouching in Photoshop CC 2014

It’s very rare that we ever get a frame from our camera that doesn’t need retouching – that’s a FACT.

Imperfections in the frame can be both ‘behind the shutter’ and ‘in front of the lens’ – sensor dust and crud on the subject.  But you’ll take photographs where these imperfections are hard, if not impossible, to see under normal viewing.

But print that image BIG and those invisible faults will begin to be visually apparent; by which time it’s too bloomin’ late and they’ve cost you money; or worse still, a client.

The ‘visualise spots’ tool in Lightroom will show you a certain amount of ‘dust bunny’ type faults and errors, but the way Lightroom executes retouching repairs is not always ‘quite up to snuff’; and when it comes to dust, crap and other undesirables on the subject itself Lightroom will fail to recognise them in the first place.

Image retouching isn’t really all that difficult; but it can be an intensely tedious and time-consuming process.

To that end I’ve stuck these HD video lessons on my You Tube channel.

In these videos I illustrate how I deploy the Spot Healing brush, Healing Brush, Clone Tool, Patch Tool and Content Aware Fill command to carry out some basic image retouching on a shot of cutlery bright ware.

I demonstrate the addition of a ‘dust visibility’ curves adjustment layer – something that everyone should ‘get the hang’ of using – as a first step to effective image retouching.

When photographing glossy, high reflectivity subjects we need to remove the imperfections and smooth the surfaces of the subject without reducing the ‘glossiness’ and turning it matt!

Please note: a couple of these videos are in excess of 20 minutes duration and they will look better at full resolution HDV if you click the You Tube icon. Also, it takes a lot longer to do a job when you have to talk about at the same time!

I hope you get some idea as to how simple and straightforward my approach to image retouching is!

Colormunki Photo Update

Colormunki Photo Update – for OSX Yosemite

Both my MacPro and non-retina iMac used to be on Mountain Lion, or OSX 10.8, and nope, I never updated to Mavericks as I’d heard so many horror stories, and I basically couldn’t be bothered – hey, if it ain’t broke don’t fix it!

But, I wanted to install CapOne Pro on the iMac for the live-view capabilities – studio product shot lighting training being the biggest draw on that score.

So I downloaded the 60 day free trial, and whadyaknow, I can’t install it on anything lower than OSX 10.9!

Bummer thinks I – and I upgrade the iMac to OSX 10.10 – YOSEMITE.

Now I was quite impressed with the upgrade and I had no problems in the aftermath of the Yosemite installation; so after a week or so muggins here decided to do the very same upgrade to his late 2009 Mac Pro.

OHHHHHHH DEARY ME – what a pigs ear of a move that turned out to be!

Needless to say, I ended up making a Yosemite boot installer and setting up on a fresh HDD.  After re-installing all the necessary software like Lightroom and Photoshop, iShowU HD Pro and all the other crap I use, the final task arrived of sorting colour management out and profiling the monitors.

So off we trundle to X-Rite and download the Colormunki Photo software – v1.2.1.  I then proceeded to profile the 2 monitors I have attached to the Mac Pro.

Once the colour measurement stage got underway I started to think that it was all looking a little different and perhaps a bit more comprehensive than it did before.  Anyway, once the magic had been done and the profile saved I realised that I had no way of checking the new profile against the old one – t’was on the old hard drive!

So I go to the iMac and bring up the Colormunki software version number – 1.1.1 – so I tell the software to check for updates – “non available” came the reply.

Screen Shot 2014 12 05 at 13.51.09 809x900 Colormunki Photo Update

Colormunki v1.2.1 for Yosemite

So I download 1.2.1, remove the 1.1.1 software and restart the iMac as per X-Rites instructions, and then install said 1.2.1 software.

Once installation was finished I profiled the iMac and found something quite remarkable!

Check out the screen grab below:

Screen Shot 2014 12 05 at 14.07.23 900x472 Colormunki Photo Update

iMac screen profile comparisons. You need to click this to open full size in a new tab.

On the left is a profile comparison done in the ColourThink 2-D grapher, and on the right one done in the iMacs own ColourSynch Utility.

In the left image the RED gamut projection is the new Colormunki v1.2.1 profile. This also corresponds to the white mesh grid in the Colour Synch image.

Now the smaller WHITE gamut projection was produced with an i1Pro 2 using the maximum number of calibration colours; this corresponds to the coloured projection in the Coloursynch window image.

The GREEN gamut projection is the supplied iMac system monitor profile – which is slightly “pants” due to its obvious smaller size.

What’s astonished me is that the Colormunki Photo with the new software v1.2.1 has produced a larger gamut for the display than the i1 Pro 2 did under Mountain Lion OSX 10.8

I’ve only done a couple of test prints via softproofing in Lightroom, but so far the new monitor profile has led to a small improvement in screen-to-print matching of the some subtle yellow-green and green-blue mixes, aswell as those yellowish browns which I often found tricky to match when printing from the iMac.

So, my advice is this, if you own a Colormunki Photo and have upgraded your iMac to Yosemite CHECK your X-Rite software version number. Checking for updates doesn’t always work, and the new 1.2.1 Mac version is well worth the trouble to install.

Black Ink Type

Black ink type and black ink switching when moving from matte to luster and gloss papers – here’s my thoughts on this, initially triggered by Franks’ reply to my previous article HERE.

And I quote:

Another great and instructive article Andy. I have the r3000 but get slightly annoyed with the black ink changes from one to the other. Some further guidance on the use of these re paper ‘types’ would be appreciated by moi ~ please ♡

Look, he’s even put a heart in there – bless you Frank, that’s more than I’ve got out of ‘her indoors’ for years!

Now the basic school of thought over this switching of black ink type is this:

  • PK, or Photo Black ink type supposedly produces a smooth, highly glossy black.
  • MK or Matte Black ink type produces a dull, flat black.
  • Using a matte finish paper requires the MATTE black ink type.
  • Using Luster or Gloss paper requires the Photo black ink type.

The PK black ink type really only produces a HIGH GLOSS finish when chucked onto HIGH GLOSS media.  Its’ got a rather less glossy and more ‘egg shell’ finish when used on a more luster finish paper. There does come a “tipping point” though where it will look a little shinier than the finish of the paper – and it’s this tipping point where theory, clever-dicks and user-guides tell you there’s a need to switch to the matte black ink type.

The Matte black ink type does exactly what point two says it does.

The third point – replace the word “requires” with the phrase “can cope with” and we’d be about right.

The forth point is absolutely true; get this wrong by printing with the MK black ink type on high gloss paper and you’ll just waste consumables and potentially end up with the type of clean up operation normally the preserve of Exon & BP. Dot gain on steroids!

There’s also an argument that the MK black ink type produces a deeper black on matte finish paper than the PK black ink type – this is also true:

4800 PermMus MKvsPK 900x692 Black Ink Type

Permajet canned profiles for Museum paper on the Epson 4800 printer using PK and MK black ink types.

As we can clearly see, the Matte black ink type does indeed accommodate a deeper black point than its counterpart Photo black ink type.

Adopting the Common Sense Approach

There are a few things we need to think about here, and the first one is my constant mantra that the choice of paper is governed by the “overall look, feel and atmosphere of the finished image” when it’s sitting there on your monitor.

Paper choice IS the final part of the creative process; for all the reasons I’ve mentioned in past blog posts.

You will also know by now that in my world there is little room for high gloss paper – it’s a total pain the bum because of its highly reflective surface; but that same surface can allow you to print the very finest of details.

But here’s common sense point number 1 – the majority of people reading this blog, attending my workshops and coming to me for 1to1 tuition CAN NOT produce images with detail fine enough to warrant this single benefit of high gloss paper.

That’s not because they’re daft or rubbish at processing either – it’s simply due to the fact that they shoot 35mm format dSLR, not £30K medium format.  The sensors we commonly use can’t record enough ultra fine detail.  There’s a really good comparison between the Nikon D800 and an IQ160 here, it’s well worth having a look – then you’ll see what I’m on about.

The point I’m trying to make is this; print on gloss from 35mm if you like; but you are saddling yourself with its problems but not truthfully getting any of the benefit – but you can kid yourself if you like!

I Lust After Luster Papers But How Lusty Is That Luster?

As I mentioned in the previous post, Calumet Brilliant Museum Satin Matte Natural is NOT a matte finish paper.

True matte papers never really hold much appeal for me if I’m honest, because they are very dull, flat and relatively lifeless.  Yes, a 12×12 inch monochromatic image might look stunning, especially hanging in an area where reflections might prove difficult for any other print surface.

But that same image printed 8 foot square might well “kill’ any room you hang it in, just because it’s so dull and so damned BIG.

True matte papers do have their uses that’s for sure, but in the main you need to discriminate between matte and what I call matte “effect”.

Permajet Fine Art Museum 310, Matte Plus and Portrait 300 are papers that spring to mind as falling into this matte effect category – and wouldn’t you know it, there are canned profiles for these papers for both PK and MK black ink type ink sets, as you can see from the image earlier in the post.

So, with regard to black ink type switching you have to ask yourself:

  • Am I using a paper the ACTUALLY NEEDS the MK black ink type?  Chances are you’re probably not!
  • If I am, do I really want to – how big a print am I doing?

In my own print portfolio I only have two images that benefit from being printed on a “dead” media surface, and they are both printed to Permajet Museum using the PK black ink type.

I had another one that looked “nearly there” but the heavy texture of the paper detracted from the image, so it was re-proofed and printed to Matt Plus, again using PK ink. It looked just the same from a colour/luminance stand point, but worse from a ‘style’ point because of the zero texture.

Along comes Calumet Museum Satin Matte Natural!

The subtle texture gets me where I wanted to be on that score, and that ever-so-soft luster just makes the colours come to life that tiny bit more, giving me a print variation that I love and hadn’t even envisaged at the time I did the original print.

Ink Type Switching

I have to say at the outset that I do NOT own an R3000 printer – I use wide format Epson printers and so have no commercial need for the 3000 DT format.  But I always advise people looking for a printer to buy one – it’s a stunning machine that punches well above it’s weight based on price point.

My Epson wide format does not hold both black ink types.  Switching entails a rather tedious and highly wasteful process; which I have neither desire or need to embark upon.

But if you have any brand of printer that carries both types on board then I’d highly recommend you to set the black ink type to PK, and turn any auto-switching OFF – that is, set switching to manual.

Right, now the super-pessimist in me shines through!

I’m not a fan of Epson papers on the whole, and there’s a lot more choice and far better quality available from third party suppliers ranging from Photospeed to Hahnemuhle, Canson, Red River and all points in between.

Now third party suppliers in the main will tell you to use one black ink type or the other – or either, and give you the correct media settings (Brilliant – are you reading this??).

But, if you have auto switching enabled, and use Epson paper, the print head sees the paper surface and automatically switches the ink to the ‘supposed’ correct type.  This switching process requires the printer to purge the black ink line and refill it with the ‘correct’ black ink type before printing commences.

Now these figures are the stats quoted from Epson:

Black ink conversion times:

  • Matte to Photo Black approx. 3 min. 30 sec
  • Photo to Matte Black approx. 2 min. sec

Ink used during conversion:

  • Matte to Photo Black approx. 3 ml
  • Photo to Matte Black approx. 1 ml

Now why the times and volumes aren’t the same in both directions is a bit of a mystery to me and doesn’t make sense.  But what is killer is that the carts are only 26 (25.9)ml and around £24 each, so 6 changes of black ink type is going to burn through as good as £25 of ink – and that’s without doing any bloody printing!!!

When ever I demo this printer at a workshop I never use Epson paper, auto switching is OFF and I never get a head sensor warning to tell me to switch ink even if I load Permajet Museum – the head sensor doesn’t warn me about the fact that I’m using PK ink.

Yes the printer could be up the spout, but using a canned PK profile the resulting print would tend to indicate otherwise.

Or something slightly more dark and sinister might be happening – or rather NOT, because I’m not using OEM paper………...What was that I heard you say?  Good gracious me…you might think that but I couldn’t possibly comment!

One thing to bare in mind is this.  For the most part, the majority of print media will work exceptionally well with the PK black ink type – BUT NOT THE OTHER WAY AROUND – you’ve been warned.  If you want to know how the captain of the Exon Valdez felt and be up to your ass in black stuff then go ahead and give it a try, but don’t send the cleaning bills to me!

I did it once years ago with an HP printer – I can still see matte black ink tide marks on the skirting board in my office……it wasn’t pretty! And it screwed the printer up totally.

Using PK on matte media will only effect the D-max and lower the overall contrast a wee bit; unless it’s a very low key image with vast areas of blackish tones in it then for the most part you’d perhaps struggle to notice it.  Sometimes you might even find that the drop in contrast even works to your advantage.

But don’t forget, you might not be using a matte media at all, even though it visually looks like it and says the word matte in the paper name.  If the paper manufacturer supplies a PK and an MK profile for the same paper then save yourself time and money and use the PK profile to soft-proof to AND to control the printer colour management.

Did that answer your question Frank – FRANK – can you hear me Frank??!!

Brilliant Papers from Calumet

Brilliant Papers from Calumet

My thoughts on two papers from the Calumet Brilliant Papers range.

museum Brilliant Papers from Calumet

Brilliant Museum Printing Papers from Calumet

As I CONSTANTLY demonstrate to individuals and groups during workshops and 1to1 tuition days, printing is so damned easy it’s ridiculous.  Provided you get all your “ducks in a row” – and that’s not the hardest thing in the world to do, considering you’ve only got 3 bloody ducks!

How hard can it be???

Notwithstanding the necessity for an accurate monitor profile (duck number 1), the paper and its profile, or colour space if you like, form the back-bone of both “soft-proof” and the final print that spews forth from your printer – they’re ducks 2 and 3 respectively.

When getting someone on the “straight and narrow path to print righteousness” I always find it best practice to make them stick to one paper until they are super-familiar with the process, and begin to appreciate the fact that paper choice is the final step in the creative process.

I never want to confuse folk with custom profiles either – if I can get them onto a paper that comes supplied with a reliable OEM profile which includes the relevant MEDIA SETTINGS for the printer (these are crucial) then my work is done.

One paper with a very accurate OEM profile that has media settings as part of the profile name is Permajet Oyster 271.  A cracking paper for general purpose printing, it’s finish suits most images, and it’s still my go-to paper for prints of general wildlife and natural history subjects.

But it doesn’t suit everything, and landscapes, seascapes, and other styles of fine art imagery are the sorts of images that spring to mind.  It’s paper-white is a little on the cool side for starters – so printing a warm tone image to it increases your soft-proof workload for starters.

So I’m always trying different papers so that I can recommend them to my clients,  but no matter how good I find them, I’ll rarely recommend them if the supplied OEM profile is crap.  With the profiling gear I use I could get a workable custom profile for toilet paper if I had to, but telling someone new to printing that they need to:

  • Spend £1500 on the gear
  • Learn how to use what looks like the most scary software GUI on the planet
  • Waste 1 or 2 sheets of paper and ink printing the test charts (it’s not a waste really but that’s how they’d see it).

isn’t a real option.

But now I’m in love with two papers from Calumet and their Brilliant Papers Museum range.  They are:

  • Brilliant Papers Museum Satin Matte Natural
  • 1 Brilliant Papers from Calumet

    Brilliant Papers Museum Inkjet Paper – Satin Matte Natural

  • Brilliant Papers Museum Silver Gloss Natural
  • 2 Brilliant Papers from Calumet

    Brilliant Papers Museum Inkjet Paper – SilverGloss Natural

 

Both these papers, in my opinion, are up there with the very best of them.  And, while they cost – size for size – twice as much as something like Permajet Oyster; they are both far more than twice as beneficial to the easy production of fine art landscapes and other images that require a bit more from the printer paper to add the final touch.

I’ve used both papers on the Epson R3000 with the Epson ink set, and on my Epson 4800 that carries a Lyson ink set, and all I can say is that I’m more than impressed, and have no trouble in recommending you give them a go.

On the Epson R3000 I used the “canned profiles” downloadable from Brilliant Papers website HERE  but you need to understand that Brilliant have not exactly been sensible here and have omitted to give you any indication of correct media settings.

I’ve actually been using media settings of WCRW (water colour radiant white) for the Satin Matte Natural on the R3000 and TFAP (textured fine art paper) on the 4800.

For the Silver Gloss Natural the media settings for both printers have been UPPPL (ultra premium photo paper lustre) and results have been superb.

Just in case you don’t understand why media settings need to be set correctly, different papers require, amongst other things, different inking levels from the print head – too much ink and the print will look dark, too little and it’ll look pale and washed out.  There is also the little matter of what’s called “dot gain”.  Some papers have a hard glossy surface, others a more rough and porous one. A nozzle droplet of a particular size might be fine on a gloss paper, but that same size droplet on a fine art rag paper might well ‘bleed’ and spread out like it was on blotting paper.  This bleeding, or dot gain, leads to a reduction in sharpness of fine detail.

So, media settings are important – they ain’t there for the hell of it you know!

The “canned” profiles plot for the Epson R3000 using MK ink for Satin Matte Natural and PK ink for the Silver Gloss Natural (sRGB included for comparison):

And for the 4800:

I swapped the plot colours around by mistake – my bad!

I always used to like the look of images printed on Permajets Fine Art Museum 310, but 90% of the time I felt the texture somehow visually ‘got in the way’.

The texture of Brilliant Papers Museum Satin Matte Natural is not quite so pronounced which means I like it better!

In practical terms the colour space of the paper, though ever so slightly smaller than the Permajet Museum paper, does give you slightly deeper blacks and that tiny bit of extra shadow detail clarity.  All in all, a very good go-to paper, especially for the more monochromatic image such as:

D4R3875 Edit Edit 599x900 Brilliant Papers from Calumet

“The Portal”

The Brilliant Papers Silver Gloss Natural.  I find it difficult to actually describe the finish as “gloss” – it’s more like a very fine grained lustre to be honest.

And the difference between the two papers?  Well, the Silver Gloss just has that little extra contrast in the medium and darker midtones – it’s a bit like adding 8 or 10 points of clarity to an image inside of the Lightroom Dev module.  I’d definitely consider this a great paper for landscape and fine art imagery that contains just that little bit more in terms of colour variation and saturation:

D4R0016 Edit 21 607x900 Brilliant Papers from Calumet

“Stepping Stones to Oblivion”

All in all two very nice papers from the Brilliant Papers range that will be seeing regular use both in my own work, and in my workshops and tuition days; though not exactly budget-priced papers they’re no where near as pricey as some – plus, don’t you think your images are worth it?

And just in case you were wondering; I too was quite surprised at just how well matched the Brilliant canned profiles for the 4800 worked out on my Lyson ink set! I’ve written custom profiles for both of these papers, and there is generally so little difference between the custom and Brilliant profiles (which are really intended for the Epson ink set) that I can’t tell the difference between the prints I’ve done so far – and I’ve done a few!

Though for my own printing I’ll always use my custom icc profiles.
