Images of an object or geographical area obtained for a plurality of optical bands. The images are transferred to a digital processor which rasterizes and interleaves the images to an output file for printing. The output file is printed in an alignment with a microlens sheet having a plurality of lenses. The lenses refract the printed image such that a viewer sees from a first position relative to the hard copy an image corresponding to the object or geographical area as seen in a first frequency band of the optical spectrum and, from a second viewing position sees an image corresponding to the object or geographical area as seen in a second frequency band of the optical spectrum. At least one of the first and second frequency bands may be a non-visible band. The viewed images may include an indicia of the optical band corresponding to the image.
