Infrared Photography
Infrared Photography shows an invisible world. It's a special type of photography that shows what cannot be seen by the human eye: the full spectrum of light. Trees and grass, that have chlorophyll, reflect IR light that it's invisible.
Recently, Lomography introduced the Lomochrome Purple. This film is very simillar to Kodak's Aerochrome (a discontinued Infrared color film) but without its infrared-sensitivity, making it a false infrared, but still produces breathtaking results.
