That was my point from the very begining: that I was disagreeing with the original choice. I didn’t expect anyone to agree with me. Just expressing dissent. 🙂
Back to business :
I’m using GIMP too, haven’t used Photoshop in ages.
Can’t say I dealt with such issues since I’m adjusting colors/shade/hues/luminance/whatever in GIMP/Krita/paint.net well, whatever is convenient, not in ePic.
Out of the top of my head, I’d hazard that if there’s an issue with GIMP’s PSD that could be because GIMP’s default isn’t PSD, it’s XCF. PSD is Photoshop format. Maybe give Krita or Paint.net a chance ? Just guesses, not promises. 😛 ^_^
