Hello, I'm an internet lurker who specializes in both the visual and written arts. I tend to talk to much to spite not having anything I wish to speak about, so please don't mind me if I start rambling on!
Nevermind, it's now more so to not mind me if I don't talk at all haha!
Programs used:
I use Paint Tool SAI the most, but I do have Photoshop(kindly given to me by my older brother (´ヮ`)), Manga Studio (kindly given to me by a friend (´∀`)), Krita (free), MyPaint (free) and I think I've got Paint.net and GIMP (my arch-nemesis!) floating around somewhere (also both free).
Uses (-SAI and PS):
Krita is a wonderful alternative to PS and MyPaint is very limited (there is legitimately no programming reason not to have a select tool) but fantastic for traditional users who just want the undo button! Paint.net and GIMP are also editing programs and both have their own purpose like opening .dds files.
