For digital portraits, I usually charge $250-350 ($250 for friends, but it's always friends).

Film is a bigger risk to you for things not turning out well, much greater time commitment. I would price accordingly.

What I don't do is charge craploads for prints. I will make a nice 13x19 print for $100 or so but I'm happy enough to give the files to the customer and have them make drugstore prints if they want.
