A preferred photographic printer (10) includes light filters (52, 54, 56) which can be shifted to selected positions for filtering respective spectral components from selected portions of a light beam (100) in order to vary the spectral make-up of the light beam, and further includes a preferred metal halide lamp (48) which produces a spectral output with substantial portions in the visible band.

System for selectively controlling the spectral make-up of visible light

A computerized video imaging system is provided which includes a target mount for supporting a target photographic transparency. A lamphouse is positioned to pass light through the transparency and includes light sources for a set of primary colors. An image sensor is positioned to receive light passing from the lamphouse through the transparency and generates video signals representing hue and intensity of the light. Image storage means are provided for storing color reference representations of the reference transparency. A color video monitor receives signals related to the reference representations and the target video signals. A computer interfaces with the light source and the image storage to calculate photographic color correction values for the target transparency.
