IMG_2924bin infrared photography, the film or image sensor used is sensitive to infrared light. the part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging.

wavelengths used for photography range are from about 700 nm to about 900 nm. usually an „infrared filter“ is used; this lets infrared (IR) light pass through to the camera, but blocks all or most of the visible light spectrum
