A little more explanation: I was compositing scanned aerial photographs and enhancing them. No one here had ever done that. To be able to composite the photos, I had to make the colors match, and the easiest way to do that was to dodge and burn on the RGB color separations individually. Photopaint wouldn't let me do that, Photoshop did it in a walk. I also needed precise geometric control at the pixel level, and Photoshop was a clear winner in that area. There wasn't any art to that, strictly technical imaging. Gromit
