A portable folding reflector positioned to "bounce" sunlight onto a model. Reflectors vary enormously in size, colour, reflectivity and portability. In tabletop still life photography, small mirrors and card stock are used extensively, both to reduce lighting contrast and create highlights on reflective subjects such as glassware and jewelry.

Nonimaging optics (also called anidolic optics) [1] [2] [3] is a branch of optics that is concerned with the optimal transfer of light radiation between a source and a target. . Unlike traditional imaging optics, the techniques involved do not attempt to form an image of the source; instead an optimized optical system for optimal radiative transfer from a source to a target is desi
