When I just did a Google search on 'model release form' I got over 50,000,000 hits reported... there's bound to be one or more of releases you're comfortable using in that bunch. [img]/ubbthreads/images/graemlins/blush.gif[/img]
But, from your description of what happened, it doesn't sound as if any other model release would have made a difference - if she didn't wanna sign, she wasn't gonna.
I've found that I can prevent that situation from happening again (yeah, you're not the only one it's happened to) by getting all the paperwork (release, photo of model with her ID, etc.) done BEFORE starting the shoot. Usually, the model has been given a copy of my coop work agreement beforehand, but regardless, if the model is not willing to sign before we start shooting, then we don't shoot. It's that simple.
Disappointing, yeah, but a lot better than spending a whole lot of time for images that, while I might own the copyright, I can't use anywhere.
