Image or reality? Leaf research needs photos and lab analysis

Every picture tells a story, but the story digital photos tell about how forests respond to climate change could be incomplete, according to new research.A new study shows that the peak in forest greenness as captured by digital pictures does not necessarily correspond to direct measures of peak chlorophyll content in leaves, which is an indicator of photosynthesis. The research has significant implications for how scientists use digital photos to study forest canopies.
