The first and very important step in modeling regime of solar radiation below forest canopies is acquisition of proper canopy picture. This review is focused on factors influencing quality of hemispherical photographs applied for modeling of light conditions under canopy. Although numerous cameras and lenses are presently offered on the market, only few types may be considered useful for this purpose. The quality of picture depends not only on quality of camera lenses and sensor, but on proper exposure as well. The overexposure (2-3 EV) based on open sky light measurements is suggested to achieve proper quality photographs with high contrast between sky and forest canopy elements.
