Rapid, reliable and meaningful estimates of forest canopies are essential to the characterization of forest ecosystems. The aim of the research was to conduct a thorough technical appraisal of existing available digital photographic methods for forest canopy estimation. The more traditionally used digital hemispherical photography (DHP), which measures the gap fraction at multiple zenith angles, was compared with methods that measure the gap fraction at a single zenith angle, namely 57° photography and cover photography (DCP). DCP is a more recent canopy photographic method, which measures gap fraction at the zenith (0°). These methods were applied in deciduous forests of beech, chestnut and Turkey oak. All photographic methods provided goo...
