What is the term for lighting your subject from three different sources?

The term for lighting your subject from three different sources is 3-point lighting. This technique is a foundational method used in photography and film to achieve a balanced and flattering illumination.

In a standard setup, 3-point lighting involves the use of three different light sources: the key light, which is the main light that illuminates the subject; the fill light, which softens shadows created by the key light; and the back light (or rim light), which adds depth to the subject by creating separation from the background. This combination allows for dynamic lighting that enhances the three-dimensionality of the subject, making it more visually appealing.

The other options refer to different lighting techniques or styles that do not involve the use of three different light sources in the same way. For example, a single light setup would only use one source and would not create the same depth and dimension, while natural lighting relies on sunlight rather than artificial sources. Soft lighting is a quality of light rather than a specific setup that involves three sources. Therefore, 3-point lighting stands out as the correct term for this multi-source illumination technique.
