infrared film

Definition: Light-sensitive material sensitised for near-infra red radiation. * May need to be used with filter to cut out shorter wavelengths (blues and greens) if it retains sensisitivity to these. * For colour reproduction, reds and infra-red are reproduced as red, green colours are reproduced blue and blue colours are reproduced green (but note green leaves reflect infra-red efficiently, so often come out red).
