ICC/Color profile question

[morpheuskibbe]

I had a weird issue with PSD files and color profiles

Someone sent me a PSD that looked all kinds of wrong when I opened it.  Affinity also popped up a message that said that it assigned the sRGB profile to this "unprofiled" document.  I tried to 'Assign ICC profile' to it and, basically, I guessed what the profile should have been a bunch.  The color looked different each time but never looked correct.

Eventually I fixed it by getting the file open in photoshop (where it looked correct) and did 'convert to profile' and changed it to an sRGB.  THEN when I opened it in affinity it looked normal.

Apparently, it was in something called "U.S. Web Coated (SWOP) v2" at least according to the photoshop dialogue (see attached) and Affinity was incapable of recognizing that fact.

How come Affinity doesn't support SWOP (it's not in the profile list) and how would I have overcome this issue if I had not had photoshop to convert it for me?

EDIT: Didn't notice right away, but it lost layer data and converting isn't working anymore... now I'm just scratching my head.

Hi @morpheuskibbe,
Welcome to Affinity Forums
Do you mind attaching the PSD file in question please? I can provide an upload link if you wish to keep the file private - just let me know.

I included a "correct" JPG which is what it looks like in photoshop, and an "Wrong" jpg which is what it looks like in affinity

 

Note its a BIT NSFW.  Its not porn or anything. but may be seen as borderline.

Hi @morpheuskibbe,
It's not the colour profile. It's an issue with layers with Blend mode set to Color Dodge.

So in the mean time is there a setting I can twiddle to fix it?  in either program?  switching to something other than "color dodge" (i honestly don't know what that means) will likely not work, though not because of bugs, just different settings.

Hi @morpheuskibbe,
This file has an advanced blending option that was disabled - "Transparency Shapes Layer" and that we do not support. If you open the File in Photoshop, select the layer 27 (same for layer 17), double-click the two squares in front of  those layers, select Blending options (should be selected when you open the dialog), tick "Transparency Shapes Layer" to enable it (which is the default), you will see that Photoshop renders the image exactly as Affinity Photo.

Ya it does.  So I guess I'll just have to use photoshop for this file then?

Yes, I'm afraid there's no way around it.
