DefinitionLight that immediately bounces off an object as it strikes. There are three types of reflection: diffuse, direct, and glare?.
More InformationMost objects cause some of each type of reflection. The differing proportions account for differences in appearance. The management of reflection is the most critical factor in achieving a well lit photograph.
DefinitionA device that is used to provide fill light by reflecting illumination from the main lighting back onto the subject. Reflectors come in a variety of materials and colors designed to offer a variety of reflective behaviors. A colored background may operate as a reflector and can color the subject.
More InformationA silver reflector will typically provide direct reflection and provide more light than a white ones which provide diffuse reflection. However, the placement of a white reflector is less critical and in some locations may provide more illumination on the subject than a silver card. Gold reflectors will reflect a warmer light onto the subject. Black reflectors are used to block reflected light from unwanted sources.
DefinitionA change in direction of light as a result of a change in its speed as the wave hits a surface.
More InformationRefraction magnifies objects and makes them appear closer. Camera lens design employs refraction.
