The effects of light on a subject depends upon the the positions of the subject, the camera, and the light source. I am fond of strong back lighting, which depends upon getting subject, camera, and light source carefully aligned. Set up correctly, back lighting has the potential of giving subjects the drama they deserve. Subjects like scrambled eggs or sorbet, for example. With a lightweight pocket camera and a small subject, the camera can be held in one hand and the subject in the other to very quickly get the lighting aligned.
