toodee Posted November 29, 2020 Share Posted November 29, 2020 Hi, I found already some similar questions related to this topic but not a simple answer. For this demonstration I use the ACEScg colorchart from here:https://github.com/colour-science/colour-nuke/blob/master/colour_nuke/resources/images/ColorChecker2014/ACEScg_ColorChecker2014.exr I use a tool like Nuke NON-Commercial, read in the file above (assuming all colorspace settings are correct in Nuke and Affinity Photo) and use a sRGB view transform. Then I use the Digital Color Meter from MacOS and read the marked grey patch value "on" the screen. Next I export a JPG and review the file in Preview and read again the value of the same patch. These are images 01 and 02. The I repeat the same steps in Affinity Photo and don't get the same result. These are the images 03 and 04. In my expectations both tools should end up with the same result. Why the the exported chart in 04 on the right side so much brighter? Do I have a wrong setting somewhere in Affinity Photo or is this a bug? Best regards Daniel www.toodee.de Quote Link to comment Share on other sites More sharing options...
