Here is the posing list I used. Some of them were must have, some maybe and some a few times. Adapt it to fit your style, niche, needs. A lot of them can be shot in portrait or landscape. They can be shot with the model facing the camera, side on and back on in some cases. Plus there are as many variations as the shooter can image. He doesn't have to shoot them all, but as you can see there's no excuse for sets with the same pose shot over and over again with little variation.
Use your imagination before you tell me it can't be done.

A lot of these positions can be used for shooting solo video. The need for movement with video is less important than still. But still a girl needs to move around a bit.
Will start on a 2 girl posing list soon.
