Optimizing forest canopy structure retrieval from smartphone‐based hemispherical photography
Methods in Ecology and Evolution, 2023 Hemispherical photography (HP) is a long‐standing tool for forest canopy characterization. Currently, there are low‐cost fisheye lenses to convert smartphones into highly portable HP equipment (smartphone‐based HP, hereafter SHP).

Standardizing the protocol for hemispherical photographs: accuracy assessment of binarization algorithms. [PDF]
PLoS ONE, 2014 Hemispherical photography is a well-established method to optically assess ecological parameters related to plant canopies; e.g. ground-level light regimes and the distribution of foliage within the crown space.
