Taking multiple shots from a fixed position allows you to turn one model into many..
Inspired by Brooke Shaden, Sean Mundy and other conceptual fine art photographers, I went through a phase of doing that type of work myself. Once you have a tripod, you can take as many shots as necessary, and clone your subject later in Photoshop. Just be sure to shoot in manual mode and lock off the focus for consistency.
Model: Mollie.
If you're interested in this type of work, I recommend you check out Brooke Shaden who takes the possibilities of working with a tripod to the next level, and usually she is her own model! She has a video training course available on Creative Live too.
