Was the question regarding people using PP or not?
I thought it was regarding whether people used
Adobe apps for PP or whether they used something else.
Personally I use some Adobe apps (Photoshop CS2, Lightroom [a bit], and InDesign CS2 [for book layouts]) combined with non-Adobe software (e.g. iView MediaPro for file/image management). But that's because I've found a workflow that works for me. It's efficient, allows me to cope with thousands of images per shoot if necessary, and provides a consistent quality I'm happy with.
That's not to say that non-Adobe won't do a good job: before I moved to the Apple platform, GIMP and ImageMagick were my workhorses on my
BSD machines.
