When nudes are shot, the images are taken with the subject taken from the front or slightly from the side. Profile shots are much less common. As I am just learning and exploring the genre, I will usually get the model to pose in profile. This tends to confuse them a bit because they are rarely asked to pose this way.
Here are two profile shots that I took last week when I shot Stephanie.
1. Head and torso
2. Three-Quarter shot
