ABSTRACT:
A photographic color printer includes a color video camera for making specialty prints. A memory is provided to store different color compositions for printing light including an initial color composition and additional color compositions which surround the initial color composition. The memory also stores camera adjustment parameters for each additional color composition so that, when the color composition of the printing light is shifted away from the initial color composition, the camera can be adjusted to the new color composition. The camera is adjusted to the initial color composition by exposing the camera to light of this composition. Following such exposure, the camera is sequentially exposed to light of the various additional color compositions. The camera is adjusted to each additional color composition in order to obtain the camera adjustment parameters which are to be stored in the memory.
