Scientific paper

During World War I, a group of American chemists, physicists and astronomers developed processes for greatly increasing the infrared sensitivity of photographic emulsions, for long-distance reconnaissance from airplanes or the ground. After the war Lick Observatory astronomers, beginning with C.D. Shane and Mary Lea Heger, used long-focal-length astronomical cameras and these hypersensitization methods to photograph the distant Sierra Nevada range, including Yosemite Valley and Half Dome, nearly one hundred miles away across the Central Valley of California. These pictures, widely exhibited and admired, strengthened links between astronomers, the Eastman Kodak Company and the public.
