Abstract
Apparatus for exposing photographic materials, for example, film or paper, for testing its response to various wavelengths of light at various intensities. The apparatus include an elongate housing divided by baffles into a plurality of compartments. One compartment contains a source of light of constant intensity and color temperature. Remotely disposed in the housing are means for mounting the film for exposure and includes a step wedge. Other compartments include filters for modifying the intensity and color of the light passing from the source to the film through apertures in the baffles; a strobe as an alternative source of light; a shutter for controlling flow of light from the source; and a spectroradiometer for analyzing the light and maintaining its intensity and color temperature constant.
