His technique from 1891 preceded the first "real" photographic film and is based on a standing wave pattern in the photographic emulsion.

This hologram only works from one viewing angle but it can be reconstructed with white light.

The holograms needed to much integration time to be of practical use. And apparently they are still very colourfull.
