Since enough people were interested, I made a tutorial about how I paint in photoshop! I hope it's understandable >.< If you have any questions, feel free to ask!
(note: if you don't have a tablet, some of this tutorial may not apply. For instance, the brush preset that I recommend would not work without a tablet)
oook I can't figure out the presets! I'm brand new to photoshop and I must not know where what you are talking about is... I found the brush tab. and first of all, I'm working with CS5, and I cant find the box that says "other dynamics" leading to the jitter stuff. I thought, surely, this must be because I'm on the wrong brush. So I checked all the brushes and none of them had that on it! and none of them are just "round brush" so I'm SUPER confused! please help!
