Used in a studio setting, rembrandt lighting technique that is used in portrait photography. Many people use it because it can produce images which appear both natural and striking with minimum equipment. It can be achieved by using one light and a reflector, or two lights. One side of the face is lit up from the main light source, whilst the other side of the face which lacks light, stays shadowed. The light creates a triangle effect but should not be longer then the nose and no wider then the eyes.
This form of lighting is when half of the subject’s face is lit, while the other half is left dark, adding a sense of drama to a portrait. The light is evenly divided over the models face. To achieve the split lighting, you put a light source at a 90 degrees to the left or right of your model. Using a reflector can help as well, the lighting can be quite harsh so the reflector adds more light to the shadowed areas.
