Single Strobe Lighting (Preparation)

A great way to learn how to light with off camera strobes is to study the catchlights in the eyes of other images. If the light hits the eyes in anyway then it will reflect off the eyes into the camera. Once you get the idea of where the light sources are coming from you then study the face and see the results of the lighting. Once you get good at reverse engineering the lighting you can tell just by looking at the face where the main lights are coming from.
