ABSTRACT:
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.
