I have a backdrop (not really a back drop its an old projecter screen) and I'm thinking of having some friends model for me, maybe some here and then going down to the park to take some more as it gets a little darker.

Does anyone have any good tips for shooting with a model, indoors, outdoors, poses etc any one got some examples of their own?
