Charging bands money to shoot photographs/take video footage of them at shows is fucking stupid. They or a 3rd party (be it a label, PR company, magazine, etc.) will pay you to license your work to be published for an album or dvd, IF THEY LIKE YOUR SHIT, otherwise, they never asked you to be there and they will carry on with the show. If you're only in it for the money, just fucking quit. Just sayin'.
