Volker Posted February 9, 2015 Share Posted February 9, 2015 I appreciate the profile settings in the preferences for the different color modes (RGB, CMYK, Greyscale, Lab), but i'm at odds with how color magement is implemented. When choosing sRGB, images with ProPhoto profile are rendered with wrong, oversaturated colors whereas sRGB profile images are displayed correctly and vice versa ( undersaturated colors for sRGB images) when choosing ProPhoto as default profile. So color management doesn't seems to work as it should ! AMPI 1 Link to comment Share on other sites More sharing options...
Uli Posted February 9, 2015 Share Posted February 9, 2015 I can confirm this. ColorSync Utilities’ Color Calculator shows that ProPhoto RGB 0-255-0 corresponds to 0-255-0 in my display profile, whereas sRGB 0-255-0 corresponds to 91-255-14 in my display profile. When I open a test TIFF image (16 bit, monochrome green ProPhoto RGB 0-255-0), Affinity Photo correctly says (in the upper left) that the image is “RGBA/16 ProPhoto RGB”. The green color, however, is displayed as 91-255-14 on my display (as DigitalColor Meter reveals). In other words, the color conversion to the display is sRGB → displayColorSpace, not ProPhoto RGB → displayColorSpace, as it should be.

ithepinky Posted February 9, 2015 Share Posted February 9, 2015 I have the same problem. I want to work in ProPhoto, but I'm not able to get accurate colors. Maybe I'm missing something and am just accustomed to using PS for years. I'd assume I'd be able to figure it out though. David4 1 Link to comment Share on other sites More sharing options...
architectNL Posted February 26, 2015 Share Posted February 26, 2015 This is a serious problem for me My working space for RAW files in PhotoshopCC 2014, Lightroom 5.7, Capture One Pro 8, and Iridient Developer is and will be Prophoto RGB (LR uses Mellissa RGB I believe which is close to Prophoto) Opening any one of my RAW files in all programs except Aiffinity gives correct colors on my calibrated monitor. Affinity gives over saturated images with a strong color cast which can only be corrected by assigning either Apple RGB or sRGB neither of which I want to use.

Alan9940 Posted February 27, 2015 Share Posted February 27, 2015 Hmm...not that this is any help and FWIW... I have my working space in AP set to aRGB and I don't use ProPhotoRGB, but 99% of my RAW digital image files from a few different RAW file formats are converted in standalone RAW converters and tagged with a custom color space built specifically for digital cameras. I have compared the view as opened in AP against PhotoLine (my primary editor on Mac) and against the view in a few different RAW converters and I haven't seen any odd and/or over-saturated colors. Oh, and I regularly calibrate my monitor. Best regards, AlanH David4 and csp 2 Link to comment Share on other sites More sharing options...
Jocho Posted June 23, 2015 Share Posted June 23, 2015 Regarding the color management, not so depth about the management instead, but the color chooser and work with different colors become quite hard, i believe this area will be improved with a color dropper more easy to use like another tool... I feel that the color selector it´s not very precise, i missed a info palete that give in real time about colors, position, measures and size of selection.

David4 Posted March 13, 2016 Share Posted March 13, 2016 I emphatically agree with this issue. I have posted too many questions begging for help, and all I am told is either NOTHING OR I ASK TOO MANY QUESTIONS. I did know what color space was being use. All I knew was, and still is, exported tiff images do not appear the same as in the AP window. My color working space is ProPhoto RGB. I use 16 bit files. I don't believe serif pays attention to this. What a waste of our time. Attempting to fix something broken beyond our abilities.

csp Posted March 14, 2016 Share Posted March 14, 2016 like allenH i do not see any color management problems with AP and i use it since the very first beta ! what you describe are very likely user errors. when you export a tiff file from AP make sure embed ICC profil is checked ! the workspace profile has no effect on files with correct icc profiles embedded when opend in AP !

Tekl Posted March 15, 2016 Share Posted March 15, 2016 @csp So you can't confirm the following behaviour? 1. Open a photo in Affinity Photo 2. Take a screenshot 3. Open the screenshot in Affinity Photo 4. If the colours are not identical, the embedded profile is not repsected. Link to comment Share on other sites More sharing options...

If the colours are not identical, the embedded profile is not repsected. you mix things up this is not what i would call an color managed workflow ! most screen shot tools use non or the monitor profile so the images must look different and give different readout values ! to clear things try what is describe here: https://forum.affinity.serif.com/index.php?/topic/18821-i-am-soooo-frustrated-with-this-soft-proofing-and-no-one-helping-sure-i-have-used-soft-proofing/?p=87440 Link to comment Share on other sites More sharing options...
Tekl Posted March 15, 2016 Share Posted March 15, 2016 Right, that's no classical color managed workflow. But when an image has the display profile embedded, the app should show the picture without color shift. I haven't found any other app with this issue. Quick Look, Acorn, Pixelmator or Photoshop work as expected. Here's what I've tested: I have an 5k iMac. When I open a Screenshot in Affinity it shows mit that the Profile "Display" is embedded. Preview shows me "iMac" instead. When I export the color shifted screenshot with embedded profile, it now looks wrong in every app. The embedded profile is "31MU97" from an external display I tested weeks ago. So Affinity seems to ignore the display settings of OS X. I deleted "31MU97" and tried it again. V1.4.1 stucks to 31MU97 (I deleted caches and prefs). In Beta 1.4.2-b3 the color shift is now less extreme, because Affinity now uses a different profile (Acer) which is more close to sRGB. When I delete the Acer profile V1.4.2-b3 switches to a Dell profile, V1.4.1 is stuck to 31MU97, I can't find out where it gets the profile. I can reproduce the behaviour on a second Mac, but there the release version does not stuck to a already deleted profile. Link to comment Share on other sites More sharing options...
csp Posted March 15, 2016 Share Posted March 15, 2016 it really gets difficult to help here what you describe is a mess i can´t understand and it seems you are not interested in taking some time to check if AP works as ist should. i also wonder if your imac is calibrated and profiled or are if just play around with different monitor profiles ? i cannot replicate this behavior with screenshot under 10.11.3 it embeds sRGB and everything works as aspected Link to comment Share on other sites More sharing options...
Tekl Posted March 15, 2016 Share Posted March 15, 2016 How so you take screenshots in sRGB? Every Mac I own takes screenshots with the display profile. I would help me a lot to take sRGB shots. I use the internal commands like ⌘⇧3. Well, the color management of Affinity Photo works well for me except for screenshots. Link to comment Share on other sites More sharing options...
csp Posted March 15, 2016 Share Posted March 15, 2016 i´m on 10.11 when i use the screenshot app i get sRGG files when i use the system shortcut i have the display profile embedded both are displayed without any issue in AP Link to comment Share on other sites More sharing options...
Tekl Posted March 15, 2016 Share Posted March 15, 2016 Cool, I didn't know that the Grab tool takes sRGB shots. But it's not very handy. Maybe you see no difference, as the profile Affinity assumes is near to sRGB. Export it to TIF with embedded profile and compare the profile names in Preview.app. I can reproduce the wrong Profile by assigning "Display" to any of my documents, experting to TIF and opening in Preview. The reason of this bug could be, that Affinity seems to look for the ASCII name of the profile. And the most monitor profiles have "Display" as ASCII name. So AP does use the first and maybe wrong match. Link to comment Share on other sites More sharing options...
csp Posted March 16, 2016 Share Posted March 16, 2016 i don´t think this has anything to do with the internal profile naming or AP. is your imac calibrated and profiled and is this profile active in your monitor pref settings. do you maybe also use a dual monitor setup ? i think the problem is somewhere on the OSX side. i would delete all monitor profiles perform a restart with p ram reset and recalibrate the display. than make sure the new profile is active and used by the system.

Tekl Posted March 16, 2016 Share Posted March 16, 2016 I deleted all profiles, reseted the PRAM and also installed the latest combo update. Nothing changes.

AndrewRodney Posted March 28, 2016 Share Posted March 28, 2016 How so you take screenshots in sRGB? What I do is make the screen capture using SnapzPro. That IS in the display color space (one MUST tag that image with the display profile for proper preview). Then just convert to sRGB! I'm using a wide gamut, PA272W so the screen capture is actually closer to Adobe RGB (1998) but that doesn't matter. It has to be tagged with the display profile (it's untagged from SnapzPro and I'd assume virtually every other such utility). Previews correctly with the right embedded ICC profile. Now convert to sRGB, done. I setup a script in a product called Hazel which automatically tags all screen captures with my display profile from one folder. Then copies that to another folder and automatically converts to sRGB. Easy to do with an Automator script. http://www.digitaldog.net/ Link to comment Share on other sites More sharing options...

All I can say is that AP, Photoshop, Lightroom etc, all match and work with various working spaces as expected. No issues. Could be user error. Could be an issue with the display profile. Does AP engineering know if their product plays nice with ICC V4 display profiles? No reason to build them, but people do, expecting it's better, only to find, it's hosed their previews due to some bug. http://www.digitaldog.net/ Link to comment Share on other sites More sharing options...
csp Posted March 29, 2016 Share Posted March 29, 2016 andrew, the problem with the non color managed second display is not related to the profile version or matrix vs lut it is simply a missing feature or bug. Link to comment Share on other sites More sharing options...
