Kite-Lofted Camera Image (Image 5)

June 30, 2010
Kite-Lofted Camera Image (Image 5) This close shot from 15 feet above the ground captures the surface textures of an old salt work in the Warm Springs area of San Francisco Bay. The orange color is caused by halophiles living in residual brine that forms in depressions left by crude earth moving. The salt ponds in San Francisco Bay are remarkable for the halophiles that flourish at various salinities with true colors ranging from vibrant green to vermillion. Each color maps the microorganisms that live in the pond, largely as a function of its salinity. The area is managed by a variety of agencies, including the U.S. Fish and Wildlife Service, whose local authority, the Don Edwards San Francisco Bay National Wildlife Refuge, has granted a research permit for this aerial photography. This image was taken by Charles Crisp Benton, a professor of architecture at the University of California, Berkeley, using a kite-lofted camera. The camera is contained in a radio-controlled cradle suspended from the kite line approximately 50 meters below the kite. The suspension techniques, developed 100 years ago, provide an aerial photography stable and inexpensive platform that is particularly useful for low altitude remote sensing.
