Ethan, Yes…I have posted in this as well. She probably saw my post.

She suggested looking at the thread: https://affinity.serif.com/forum/index.php?/topic/4712-color-management-wei… <https://affinity.serif.com/forum/index.php?/topic/4712-color-management-wei…> The problems she saw derived from AP not using the correct monitor profile. Good luck! Ethan

You might also need to contact Affinity's tech support when all is said and done.... b& Tech support is insulated from the public. The blog, or whatever it is called take questions and distributes answers. Tutorials are the same. Nothing really addresses color management. d

Ben, it is ProPhoto RGB. D > I will have an image file, ProPhoto RGB, 16-bit tiff in a working folder. Reopen this image file in PS CS5 (or) LR 6.4 and the image file looks the same. This very same image file, not manipulated in Affinity Photo, and opened in Affinity Photo, does not look like the image file opened in the other two applications. > > What should I be doing? In Affinity Photo, View menu => Studio => Info. Make sure it says that the profile is ProPhoto. If not, Document menu => Assign ICC Profile and set it to ProPhoto. If that doesn't work, something else is going on.... Cheers, b&

Is there still value in a display that is "tailor-made" for my very unique color matching functions, in your opinion? / Roger -----Original Message----- From: Max Derhak [mailto:Max.Derhak@onyxgfx.com] Sent: 28 mars 2016 12:45 To: Roger Breton <graxx(a)videotron.ca>; ''colorsync-users?lists. apple. com' List' <colorsync-users(a)lists.apple.com> Subject: RE: Quantum Dot Tech - cheap wide gamut but is it ready for mainstream? Using narrow primaries to discover color matching functions for an individual is different than using them to perform color reproduction with the intent that the observed appearance by multiple observers is the same. The Guild and Wright experiments resulted in multiple individualized color matching functions that were then averaged together to establish the "standard" observer. Thus the standard observer doesn't necessarily predict the color matches of individual observers - especially when narrow primaries are used. Things are much better when broad primaries are used since the slight shifts in matching functions aren’t as critical. A study of observer variability relative to narrow primaries was performed by Asano with results that can be found at (http://www.cis.rit.edu/~yxa8513/Publications/Paper_CIC2014.pdf) Max Derhak (PhD) Principal Scientist -----Original Message----- From: Roger Breton [mailto:graxx@videotron.ca] Sent: Monday, March 28, 2016 12:11 PM To: Max Derhak; ''colorsync-users?lists. apple. com' List' Subject: RE: Quantum Dot Tech - cheap wide gamut but is it ready for mainstream? Please excuse my ignorance, Max, but what's the difference between this type of display narrow primaries and the original 1920's Guild and Wright RGB colorimetry experiments where narrow primaries were also used, as far as observer metamerism is concerned? / Roger -----Original Message----- From: colorsync-users-bounces+graxx=videotron.ca(a)lists.apple.com [mailto:colorsync-users-bounces+graxx=videotron.ca@lists.apple.com] On Behalf Of Max Derhak Sent: 28 mars 2016 09:56 To: 'colorsync-users?lists. apple. com' List <colorsync-users(a)lists.apple.com> Subject: RE: Quantum Dot Tech - cheap wide gamut but is it ready for mainstream? One of my concerns with displays having really narrow primaries is that they are subject to much greater observer metamerism (among color normal observers). The problem of measuring for calibration is compounded with the problem of getting observer agreement on appearance. Max Derhak (PhD) Principal Scientist Onyx Graphics Inc.

Rather inexpensive for a large gamut monitor. Intriguing color formation.

Charles, How would reading the emitted colors from this type of display be any more difficult for a spectral device than any other kinds of displays? / Roger -----Original Message----- From: colorsync-users-bounces+graxx=videotron.ca(a)lists.apple.com [mailto:colorsync-users-bounces+graxx=videotron.ca@lists.apple.com] On Behalf Of Charles D Tobie Sent: 25 mars 2016 10:59 To: 'colorsync-users?lists. apple. com' List <colorsync-users(a)lists.apple.com> Subject: Re: Quantum Dot Tech - cheap wide gamut but is it ready for mainstream? I’ve been waiting with interest to see Quantum Dot technology reach the market. However, after Apple bypassed Quantum Dot due to ecological issues, my enthusiasm has been somewhat curbed. There are other issues here; starting with this being a low resolution display for this day and age. I would also wonder about uniformity in a screen of this price range. And, for color management, there is the issue of being able to turn off the SmartContrast features. Finally, there is the question of what devices can effectively read, calibrate, and profile the display, given its new and unique screen type. I’ll be interested to hear answers to these issues from those on this list. C.
