David Doubilet (born 1946, New York) began diving at age 8 and photographing underwater at 13. Since his first National Geographic assignment in 1971, he has produced more than 70 stories for the magazine, making him the most published underwater photographer in its history. His work spans coral reefs, shipwrecks, kelp forests, open ocean encounters, and river systems across every ocean on Earth.
Doubilet is perhaps best known for perfecting the over-under or split-level photograph: an image that simultaneously shows above and below the waterline in a single frame. This requires custom dome ports, split neutral density filters or graduated ND gels, and precise exposure management to balance the bright sky against the dimmer underwater world. The result creates a sense of parallel worlds - the aerial and the submarine - that no other technique can replicate. His split-level images of coral reefs with stormy skies above became the defining image type for marine conservation campaigns.
Water absorbs red light within the first few meters of depth, leaving the underwater world in a monochromatic blue-green. Doubilet pioneered the use of large-format underwater strobes to restore full color at depth, often positioning multiple strobes wide to avoid backscatter from suspended particles. His color work reveals the orange, red, and violet hues of coral and sea creatures that the human eye sees only faintly without supplemental light.
Doubilet's work has documented vanishing reef ecosystems - particularly following coral bleaching events driven by ocean warming. His 2016 and 2022 coverage of the Great Barrier Reef bleaching events, shot in collaboration with partner Jennifer Hayes, brought wide public attention to the crisis. The Doubilet Foundation supports ocean conservation and early underwater photography education.

A Look is not a filter. It is a set of stored decisions the pipeline reads before it makes a single frame, so two videos in the same Look actually match.
