This document provides information on three studio lighting techniques: Rembrandt, butterfly, and edge lighting. It describes the basic setup for each technique, including the placement of the key light relative to the subject and camera. Rembrandt lighting uses a 45 degree key light and optional fill light to create triangular shading under one eye. Butterfly lighting shoots a key light down from high above at a 70-80 degree angle. Edge lighting separates one side of the face from the other with a 90 degree parallel key light. Students are assigned to capture portrait images using each technique with variations and reflect on their studio setup and any technical errors.
