Infrared photography refers to photographing subjects in the range of the infrared light spectrum. The human eye perceives light between a wavelength of 380 and 780 nanometers. The light that lies between 700 and 900 nanometers is called infrared.
With the help of infrared filters, which block the visible part of the light and let only light in the infrared range through, it is possible to do infrared photography with current digital cameras.
Filter im Bereich von 590 nm bis 830 nm rufen Farbverfälschungen hervor, welche ebenfalls zur Bildgestaltung eingesetzt werde.
