Heri, gimp is free. Photoshop is not. Some use gimp for personal reasons, many it is just money.
I see… I used PSP7 for a long time before I was able to afford Photoshop (and since I don’t like pirated software).
a noise modifier like in max, but working with maps, would be a must for me …
And if you are just so use to the photoshop interface get gimpshop. It puts a photo shop interface on top of theGimp
Because Photoshop isn’t 930 € better for their use?
