Special wide-angle photographs are used to describe a point on the ground in terms of the vegetation and topography surrounding it. Dot grid counts can be used to describe areal extent and distribution of the canopy in relation to the photo point. With the aid of sun path overlays, the photos provide a means for interpreting canopy effects on direct solar radiation, and a method is described for interpreting this canopy-insolation relationship in terms of "sunlight factor." Secondary applications of canopy photographs are also described, including species identification and measurements of distance, height, slope, aspect, and basal area stocking.
