ABSTRACT:
A system produces a standardized image of an object from an intermediate object recorded on film. An image of a spectrum of the light source illuminating the object is recorded on the film together with the image of the object. The image of the spectrum on the film is recorded by a film scanner and compared with the spectrum of a standatd illuminant. Color correction data is generated from the comparison. The color correction data may be used to control a photographic printer to produce a color corrected print. The color correction data may also be used to correct a digital image of the object produced by scanning the image of the object on film.
