I'm fascinated by the subject. I don't work for anyone pertaining to this subject. It's important to me as an amateur. In a nutshell, you can create XYZLUT profiles using DisplayCal on MacOS and the OS will let you select them in the Displays > Color panel without complaint then various Apple-supplied programs will just render your graphics completely wrong. Adobe works. Complaining to Apple is unproductive, and Florian had to put a caveat into the DisplayCal UI to tell users to avoid that style of profile on Mac. I suggested he take it up over here at the "Apple Colorsync Mailing List" though he was doubtful, noting that this list is mostly talk about prepress. As I was looking more into the matter, my experience is that depending on the profile I use on my up-to-date Mac, I get subtly different renderings depending on which software I use to work with graphics, even when all are supposed to be color-managed! I wrote these concerns up (not very well) and submitted them on this forum a few months ago, but no one here cares about Colorsync anymore. You guys all use Windows, OMG. Who knows why Apple even keeps this list around any more> Maybe because this place used to be a hotbed of well-informed and adventurous discussion, back when good 'ol Bruce Fraser was writing clear tracts about how to make color management work in the "real world". (The Epson Inkjet list was also a great forum, back in the day), So, having watched this stuff evolve for decades, I'm dumbfounded that for most users, color-management still is a complete mystery of behaviors, and more complex than ever. Kind of like the American commonwealth. I've no axe to grind re platforms. I work with Mac, Windows and Linux (I lived through the Unix Wars and done systems programming for novel super-computer architectures on Unix. And I've done tons of IT for these platforms. My personal systems are Apple (and VMs for the others), because I found Mac most elegant around time of Centris 650 when I bought my first home system, a long time ago in a galaxy far, far away. And the desktop publishing revolution belonged to Mac. I hate Microsoft as a general rule. Now everyone hates Apple. I see history sort of repeating i(it never really does) with iOS and Android. It pleases me that Microsoft (Balmer) thought phones were stupid in 2007 and a market not worth pursuing, and when they discovered how wrong Balmer was tried to re-invent Windows the mobile wworld just rejected them. Meanwhile Mac had gone Darwin. Saying yes to Android is saying please hijack my mobile and dox me for ransom, unless it's Android straight from Google. But I'm not invested in seeing any platform succeed or fail. My heart really lives with Richard Stallman's philosophy and work. Industry always thought he was a villain because he advocated that ordinary people should take interest in and ownership of tech that's crucial to their futures. So I returned to this list because I found DisplayCal, thought it's completely awesome, find the people working on it a super intelligent and well-informed, and when they said they ran into a problem that affects my platform of choice, I figured I should at least come over here and make a stab at seeing whether there's any traction with Apple to get it fixed. Along way, over at DisplayCal forums, I'm socratically learning about new trends in color and trying to connect these to old interests. Two of my favorite topics are Charles Poyton's wonderful expositions on the importance of understanding gamma—I can remember a guy named Timo who called out problems with non-unity gamma-encoded working spaces and RGB blending in Photoshop and how everyone thought he was a crank because he advocated high-bit linear light editing. A long time later, Adobe added a "Blending Mode Gamma" option to Photoshop. Good work Timo! There was a guy named Dan M. who taught photoshop CMYK by the numbers and he went through a phase where he taught all these prepress guys to "Move to Lab" in Photoshop under an 8-bit regime. Completely unaware that Lab coding efficiency is about %35 percent. Dan was a stickler for quality, but he had no problem that a single editing move could throw have of the information away. And there was endless struggling with platform-dependent color-rendering differences, especially re Epson. Andrew Rodney will no doubt recall this sort of stuff. My current peeve is the denigration of sRGB. It's a color-space that makes so much sense. And I'm super excited about new wide-gamut displays, and more color. At same time I see how these have been such a can of worms for so many early adopters. There's an amateur GIMP aficionado—I can't recall her name at moment—who has some great web write-ups on about how when you say sRGB, it's not even clear what you're talking about because there are numerous profiles circulating define it differently. Holy cow! And she has this great tract about how you can have a wide-gamut display that can claim Adobe RGB coverage, but actually significantly not cover sRGB. I thrive on these sorts of contentions, where when you study a matter and talk it through, community understanding evolves. (If I were better at math, I would've been all over the quantum mechanics revolution and the conundrum of the two-slit experiment, and quantum computing!) And what's a "quantum dot"(R)(TM) OLED technology? Etc. Anyway I have fun think about this stuff and never mind bones of contention. I love the feeling of when I think I understand something and I'm wrong! And also Of course, I'm sometimes just stupidly wrong, like everybody. BTW—I liked your graph of the 2D coverage for the new NEC, P3, Adobe and NTSC. Thanks for taking the time. And happy to see you over at DisplayCal forum. That SW is super great and it's a lively spot.

DXDIAG (DirectX)

In my everlasting quest for all things color management, I stumbled on a report which showed in text format, my monitor "primaries", on Windows. I bet the same information is available somewhere on MacOS? Here's a partial listing of the DirectX report, in response to the 'dxdiag.exe' entered on the command line (an amazing wealth of information) : ------------------ System Information ------------------ Time of this report: 12/27/2019, 10:06:58 Machine name: XPS8930 Machine Id: {DD9A4370-91B8-4345-89FA-C479EE2FB635} Operating System: Windows 10 Home 64-bit (10.0, Build 18362) (18362.19h1_release.190318-1202) Language: English (Regional Setting: English) ..

Snip .. It's interesting that the reported 'Primaries' chromaticities correspond to the 'Native gamut' - and not the current values, why? Yet, the White Point information is correct. Best / Roger

RE: i1Pro and monitors

So, from the arguments presented, anything that "breaks" the incoming spectra into small bins is bound to receive "less photons", in all, in each bin? Whereas colorimeters are usually designed with "large collecting areas", which allow them to collect "more'" photons ", more rapidly or, at least, to collect whatever available photons more rapidly? / Roger -----Original Message----- From: colorsync-users <colorsync-users-bounces+graxx=videotron.ca(a)lists.apple.com> On Behalf Of Pat Herold via colorsync-users Sent: December 10, 2019 3:33 PM To: colorsync-users(a)lists.apple.com Subject: Re: i1Pro and monitors I would not choose to use the term “less reliable,” but I think I understand what they are trying to say.

Good article - never obsolete. Thanks Mr. Rodney. There's a point, on page 3, in the middle of the first paragraph, where he writes: "If the sample is dark we may need to spend an entire second on each step to get an accurate reading. That's over 5 min to take one measurement!". That's indeed a long time. I recently got my hands on a good instrument and I'm finding - the hard way - how long it can take to measure down to RGB = 0,0,0. I'm still not clear on the creation of "XYZ filters", though? . / Roger From: Andrew Rodney <andrew(a)digitaldog.net> Sent: December 9, 2019 10:56 AM To: <graxx(a)videotron.ca> <graxx(a)videotron.ca> Subject: Re: i1Pro and monitors Yes, see: http://lumita.com/site_media/work/whitepapers/files/xrite-wp-3a.pdf Andrew Rodney http://www.digitaldog.net/ On Dec 9, 2019, at 5:33 AM, Roger Breton via colorsync-users <colorsync-users(a)lists.apple.com <mailto:colorsync-users@lists.apple.com> > wrote: I was up on some popular UK web site dealing with monitors galore (tftcentral) and I stumbled on this comment, which made me pause : "An X-rite i1 Display Pro colorimeter was also used to verify the black point and contrast ratio since the i1 Pro 2 spectrophotometer is less reliable at the darker end.".

Thanks Jeff. I am looking at the specs of the ProArt PA27AC and I can’t help notice the “Factory precalibrated” claim? Meaning, in essence, that a user could simply “select” some “gamut” and the panel chromaticities are controlled tight enough at the factory that there is no need to measure the display?
