The self-contained amphibious underwater Calypso 35mm film camera was conceived by the marine explorer Jacques Cousteau (1910—1997), designed by Jean de Wouters and manufactured by Atoms in France. It was distributed by La Spirotechnique in Paris from 1960. The camera operates down to 200 feet / 60 metres below sea level. The Calypso was sometimes advertised as the “CALYPSO-PHOT”.
