I’ve had Paint Tool Sai sitting on my computer for a while but I never really tried it out because I do not react well to change.
The main difference between Sai and Photoshop (besides Sai’s circa 1997 style interface) is that Sai has a line stabilizer which Ps6 doesn’t.
Get yourselves together, Adobe people. You’d think Photoshop would have a line stabilizer.
Another nice feature is that it doesn’t run up the CPU very much. (Looking at you, Adobe.)
Anyway, I drew a quickish thing to see if I could use it without getting very very angry and it worked! Coloring it was a bit weird seeing as clicking Multiply didn’t seem to do anything, but I guess it’ll take some figuring out.
