A reflectographic apparatus, equipped with an image processor, has been used to obtain a trichromatic image of paintings including both visible and infrared (700-1000 nanometer) regions. The first step has been to reproduce with MIPP (Multispectral image processing of paintings) images similar to those obtained with infrared Kodak color film. A good discrimination of both pigments and overpainting is possible with this technique which operates in a more flexible and powerful way than infrared false color photography. Results are shown relative to a test panel and a tempera painting with extensive overpaint. The possibility of utilizing this technique to correlate a single pigment with its MIPP image is now under investigation.
