National Geographic : 2005 May
FROM OUR ARCHIVES Flashback CORAL REEF COLOR ABit Too Flashy The world's earliest underwater color photography began with a bang. Ichthyologist W. H. Longley and GEOGRAPHIC photographer Charles Martin spent months coordinating divers and dory boats off Flor ida's Dry Tortugas to take the first ever underwater Autochromes of sea life (including the hogfish, above) for the January 1927 issue. To light the sub marine world, pontoon-borne pans of magnesium powder explosives (right) were "discharged by the submerged photographer at the exact moment of his finny subjects' best posings." The resulting "blinding and deafening detona tion" had drawbacks. "On one occasion," the article notes, "Dr. Longley was seriously burned and inca pacitated for six days by a premature explosion of an ounce of powder." -Margaret G.
