Hello, all.  I've been working in both Painter and Photoshop for a a little while.  I really like some aspects of both.  However, I was wondering if there was a way to create brushes that mimic some of my favorites in Painter.  For example, I would like to get a "loaded pallette knife" and a "dry brush" effect.  Is this possible in Photoshop, whether through adjusting default brushes, or downloading some?

Thanks for your help
