Who Pays Photographers?
Great web site that launched this summer that tracks what photographers are being paid.
A caveat: You need to know what you’re in for before you do a shoot. There are several posts in here where it is clear the photographer didn’t have a contract before hand (or just didn’t read it) and is a little bitter after-the-fact. Everything is negotiable and that includes your ability to say no.
