If you can only get one great picture out of a shoot, that will not be enough for a photo set. A good erotic photo set should include a series of photos and tell a story. Occasionally, for fetish themes including corsets, ballet shoes, hobble skirts and other extremely restrictive clothing, it may be easiest to start out nude and get dressed to create a photo set story. Generally, however, a photo set means the model should start out dressed in a cool and interesting outfit, which expresses his or her personality well. Over the course of a photo set, the model would usually seductively remove her clothing, piece by piece, ending up in more explicit poses by the end of the shoot. On average, a good photo set is usually around 60-120 images, but this will vary depending on how creative you and the photographer get with the poses and how explicit the shoot is.
