Hi,

I'm getting lighter blacks in Affinity Photo's canvas than in actuality. So the exported image has darker blacks than what I'm seeing on the canvas. Why is that? Please check the screenshots below. My Photo version is 2.5.7.

@Alex_M I see the difference, but your screenshots don't really provide enough information to answer exactly why. Maybe it's "Paint" that is inaccurate, or your export settings.

Suggest you upload your original AP file, your exported file, and a screenshot showing all your export settings for a clearer picture.

Hi @Alex_M,

I believe the difference you're seeing is because the Affinity apps are colour-managed, Microsoft Paint isn't...

The image is darker also in XnView which should be color managed.
Attached below are the source file, the exported PNG, and the export settings.

@Alex_M The afphoto and png files are identical. I overlayed the PNG on top of the afphoto file, set it to Difference layer blend mode, and the preview is totally black (even in the Info panel). Both files open as RGB/8 with an sRGB profile. I'm not sure if the forum software modified your PNG image or not when uploading. 

The two files look and measure the same on my Mac in both AP v2.5.7 and XnViewMP v1.8.3. I used Apple's Digital Color Meter and the sRGB readouts are the same in the locations I checked. Tonality sometimes "looks" perceptually different if I relocate the images to different locations on the monitor, due to background lighting, reflections, etc, which can sometimes fool my eyes. But based on the above two tests, the files appear to be identical tonally.

Perhaps it has something to do with your color management settings? People on the forum sometimes recommend setting the System Monitor Profile to sRGB if there are anomalies or colors are off (which never made a lot of sense to me, but seems to work). I've never had that issue with my Macs, but apparently some people do. Or perhaps it is a Windows issue. I've read that Windows recently changed their color management, which hasn't been perfect. Being a Mac guy, I can't comment on that. Perhaps a Windows user can help. I'd include your Windows version and a screenshot of your system color management settings so they can have more info.

Thanks so much for the help

You're welcome. I hope some Windows expert steps up to give you some guidance. I'm out of my element in a PC.

That fixed it. Thanks! I didn't have the sRGB profile loaded. Now colors appear correct in Affinity Photo.
