Do You Have a Session Fee?

If i feel that if they don't buy any pictures, i've still made enough money for the effort that i've put in. It's never happened that somebody's bought no pictures. But if they did, i would, of course, be disappointed, because it's my ego would be damaged. I didn't manage to satisfy the client. From a purely financial point of view, my costs are covered. So it's not a loss from a business point of view. The afobill is going to take you to to set up and do the shoot right? Right?
