Taken may 29, 2015, from underneath Meadowlily bridge, which is the dividing line between the Meadowlily Woods ESA operated by the city of London and the land owned by the Thames Talbot Land Trust. Taken with specially modified camera that shoots only black & white infrared light. Light visible to the human eye goes roughly from 400nm (violet) to 700nm (deep red). The spectrum of this photo is from 780 to 850 nm, far beyond the range of human vision. In this light, all healthy green plants appear white as they reflect IR light. Unhealthy plants will not appear white, which is why IR photography can sometimes to be used to identify sick plants and trees (fungus, disease, insects, etc) before the problem becomes visible to the human eye. enjoy
