The more you learn about digital painting, the more you'll begin to find tool synthesis.  These are techniques that require the overlap of two or more simple tools.  The combo described in this video is one of my favorite: hard and soft.   

The Ctrl+Paint Library is full of videos that explain individual tools.  If any of the concepts in this demonstration are unfamiliar to you, make sure to check out the free videos linked to the right.
