During my free time over the past month or so, I’ve been working on custom Photoshop brushes preparatory to one of the classes I will be taking next quarter. I drew various brush tips out in ballpoint and scanned them, applying various presets to them. For the most part they came out fairly painterly, as opposed to photo realistic, which is fine for my purposes. below are examples of a few of my favorites:
Virtually all of them have pen-based controls of some type, so they do require a tablet, but they can probably be easily modified to work on a mouse.
