Distance to Subject and Relative Size of Light Source

The apparent size of a light source depends on its relative size to the subject and its distance from the subject. The relative size of a light source has a dramatic effect on the shape and brightness of the highlight as well as the softness of shadows cast by the light. A light source that …

Understanding Reflections

Generally, all objects reflect light. How the object reflects light determines its reflectivity. Smooth surfaces reflect light at the same angle that the light falls on them. This is known as the angle of reflectance. Textured or unsmooth surfaces tend to be less predictable in how they reflect light. This becomes important in photography since …

What is an Umbrella?

Photographic umbrellas are constructed similar to a rain umbrella, but made with materials that control light. Most umbrellas are black on the outside with a reflective surface inside.
