DescriptionThe canopy camera is a device of new design that takes wide-angle, overhead photographs of vegetation canopies, cloud cover, topographic horizons, and similar subjects. Since the entire hemisphere is photographed in a single exposure, the resulting photograph is circular, with the horizon forming the perimeter and the zenith the center. Photographs of this type provide a means of studying the relationships between canopy coverage and such things as precipitation interception, wind, evaporation, radiation, temperature, tree growth, and forage production. Coverage and distribution of the canopy are put in quantitative terms with the help of grids, which are placed over the photos.
