These are the two main graphics editing programs that I know about. If there are others, feel free to tell me or post them in replies.
Personally, I prefer GIMP for many reasons. First, it is a free program, which, at 14, is very necessary. Although I did have an illegal version of photoshop, I removed it because I knew it was wrong, and I really didn't use it anyways. GIMP is the better program in my mind anyways. Although the open time is very long, especially if you have brushes (more especially if you got bored and downloaded over 2000 brushes from Devianart,) GIMP is more accessible. Not only is it quick and easy to get used to, there are dozens of available tutorials.
Please, post here if you would like more information, or just to pick one over the other, but please include reasons to refrain from being a spam post.
JaGgEdGe, do you get your brushes from a single source or just wherever you can find them? Same with the tutorials- I'm going to say that the interface is not that user-friendly so it does take some getting used to.
I use OpenCanvas- which is mainly a tablet-based watercolors emulator. It's much more simplistic and focused as it's not an image editor like the GIMP or PS, but rather a painting program like Paint.NET, only...not Paint.NET :P
I'm also looking for lightbox programs- right now I'm using a free version of Plastic Animated Paper (PAP), but I don't know if I wanna fork out 90E for the home edition. Anybody got some decent alternatives for doing frame-by-frames?
I prefer Photoshop. Just because I think that it is easier to use. Because I tried GIMP, and I couldn't get used to it. And there are also a lot of online tutorials for Photoshop. And I think Coral Paintshop Pro is another imaging software. Also Cinema 4 is another one I think.
Well, the it being illegal, and also lagging up my PC. I figured I'd mention the feeling bad to not look as bad for doing it, but yeah, you're mostly right. It was only CS2 anyways, so yeah =/. By the way, I can't get on JaGgEdGe, so this is my new permanent account.
I find that GIMP is much better for graphics creation, and photoshop is better for graphics editing. A copy of Adobe Photoshop 7 came with the software bundle on my computer, so I didn't have to pay $700 for it, but I still prefer GIMP when creating artwork. I mostly used it for making sprites for a game called The Battle for Wesnoth.
