What is the most effective portrait lighting setup using 2 lights?

The most effective portrait lighting setup using 2 lights is the classic Rembrandt lighting technique. This involves placing one light at a 45-degree angle to the subject's face and slightly above eye level to create a triangle of light on the cheek opposite the light source. The second light is positioned on the opposite side of the subject to fill in any shadows and provide overall illumination. This setup helps to create depth and dimension in the portrait while highlighting the subject's features.
