I just went back through over 900 liked posts and dug out all the art tutorials so i can keep track of them. I guess this might be helpful to some of you guys, so here you go.
Here we go then!
Freeware
Alchemy - this is a really fun program. You play around making abstract shapes until you start to see something in them, kind of like a Rorschach test. Then you use the shapes as a base to draw it from.
MyPaint - a pretty decent painting program that also has the benefit of working on Unix systems.
openCanvas 1.1 - I haven’t used openCanvas in years but it was a nice program with a pretty unique feel to it.
ArtRage - Only used this a couple of times donkey’s years ago just before I got oC, but I’ve heard good things about it.
The GIMP - In a similar vein to Photoshop, but free. I couldn’t get on with it when I tried it out a few years ago, but it’s pretty popular and is available on Unix systems and Macs.
Sketchbook copic: a bit different program
Not-free-ware
Photoshop - Standard painting fare. Probably the most flexible program (particularly the latest versions) but not designed to act in a “natural” way. If you’ve used it for painting versus something like Painter you know what I mean. Who the fuck pays for it though? Google “Photoshop tumblr masterpost” and take your pick.
Paint Tool Sai - Far more affordable and definitely worth paying for if you can. The brushes are very decent (especially when they’ve been tweaked a little), the gui is simple and intuitive, and I dare you to find a program with which making smooth lineart is easier.
Corel Painter - My program of choice for most things. More tools than you could ever possibly use and pretty cheap on a student license, providing that you can prove you’re a student! It’s got a few bugs but if you want realism or a more natural feel than PS or SAI this is the program for you.
