Some time ago, I made comparisons between different types of art software available. I compared Krita and Gimp, then I compared Krita and PaintToolSAI. Now it’s time to look at what the pros use. I’ll begin with procedure, explain the gaps in free software, and then discuss how ClipStudio Paint fills in those gaps. Finally, I’ll throw in alittle bit about what I think of Toon Boon Harmony.
