Beyond the spectrum of light visible to the human eye which is roughly between 400 and 700nm, one finds infrared light, which we can perceive by way of special films, black and white as well as colour, and today, via digital sensors, at least those without anti-IR filters.
In order for these different media to fully record the effect of the inner spectrum of infrared light, one needs a filter that blocks the visible spectrum and lets infrared light pass through. That is precisely what the 007 filter does.
The resulting image will vary considerable depending on the film or sensor used.
Black and White
With infrared black and white film, the image taken will have a characteristic aspect: blue skies will become almost black and vegetation will take on various shades of white, giving it a surreal appearance.
With infrared colour film, the image will present absolutely surrealistic tones, shifting colours.
