Proportional Modeling System

The modeling system aids the photographer in the composition of a shot by providing a continuously burning light source that imitates (models) the flash illumination. In order to be defined as proportional, the modeling light must imitate the flash in two important respects. First, it must provide the same pattern with various modifiers (reflectors, softboxes, barndoors). Secondly, it must accurately track the flashpower in order to show lighting ratios when two or more lights are used in a setup.
