Speaking strictly for myself...
When I create a mixed fractal/other program pic, I tend to post it in both galleries. I also like to post the untouched fractal as well, to show where the starting point was. People seem to like to see the before and after pics for comparison and discussion. (Of course it was easier to do this when I could post 3 pics a day...grin)
There are many of us fractal artists who do post-work, and we are usually quite cool about it here. It tends to be a personal decision in the end.
Good question for a round-robin discussion...
