Brightness is ignored when exporting from AffPhoto to .png file

[aymanzone 10]

Hi,

Anyone noticing Brightness of image getting ignored when exporting from AffPhoto to .png file? Perhaps it's not only brightness, but this is what I am changing right now.

The color/brightness doesn't take affect. I've posted screenshot of this here https://imgur.com/I0ySBFY and I even cranked up the brightness to 70% and saved the file.

Also, when I resize the Windows 10 image viewer, I can see the .png colors flicker. Proof https://imgur.com/IAsFhhB

I've saved all the changes and use standard way to export to .png https://imgur.com/HcYqgvh

I've exported tons of files from Affinity Photo and Affinity Publisher and never seen this before.

Anyone seen this behaviour before?

Thanks

Is it possible that your .afphoto file is CMYK?

PNG only supports RGB, and exporting a CMYK document to PNG would show a color change like that.

hi @walt.farrell I discovered I have same problem with open source software, Gimp 2.10 software.

The source file is a .png and it's GIMP built-in Linear sRGB. When I convert it to sRGBA ICE61966-2.1 it seems to have solved it. (edit). I don't think I would have tried this if not for your comment. Thanks.

Thanks

You're welcome.

I wouldn't have expected that effect, but it's good that you found a solution
