Infrared photography Wikipedia

In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as nearinfrared to distinguish it from farinfrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm. Film is usually sensitive to visible light too, so an infraredpassing filter is used; this lets ...
