oh, I am sure that everything can be matched
just with an effort that professionals will not afford.

Unless, of course, things have moved very much since I was a more active photoshop wizz.

years back my hobby was into composite photography, combining 20+ elements from different photos into realistic composites resulting in 10GB+ files. Pure fun and frustration.

I tried to move to Linux and failed miserably, Gimp just was just not there. But - to all fairness - I am out of the loop. After all this time Photoshop just fits like a glove and every effort to go back to trying Gimp sounds like climbing a mountain.

You might have just prompted me to try again.
