Abstract
Embodiments of the invention relates to cameras and flash photography, and to modulating intensity of light over time and space to subjects in an associated composition. As the composition of a photograph is created, subjects in the composition are metered and flash illumination is determined. A mask is created from an array of filters. The mask is a pattern of opacity of the filters, with the pattern modulating output of the flash. The mask pattern is applied to an associated flash head so that an exposure of the composition is made with the masked flash. Exposure of the subjects in the composition is balanced through a selective illumination of the subjects by the varied intensity created through the mask.
