1926 – The first colour photographs (Autochromes) taken underwater by W.H. Longley and Charles Martin appeared in the January 1927 issue of National Geographic Magazine. The photos were taken in Florida’s Dry Tortugas. Longley and Martin used explosive magnesium flash powder on a raft to light the scene from the surface.
