It was also very sensitive to visible light and had to be loaded and unloaded from the camera in total darkness. This didn’t just add a colour caste but changed all the colours (since the infrared is invisible) and stacking filters changed all the colors in strange and mysterious ways.īlack and white infrared film was simply much more sensitive to infrared light. You could also change the colour combinations by putting colour filters on the end of the lens. Since infrared light is not visible, arbitrary colours were associated to the layers, so it was also called false-colour film. Infrared colour film had layers of infrared, red and green, and missed out the blue. Infrared light comes in below the red frequencies and ultraviolet is above blue, though ultraviolet is not relevant here. Normal photographic colour film has layers of red, green and blue. Colour infrared film seems all but unavailable now whereas there are a few avenues for B&W IR film. In ancient days of yore, decades ago, we had both colour and black & white infrared film.
The IR explanation may be of general interest to photographers and others may just be interested in the images (there’s lots of text but also lots of images further down). I have upgraded my IR camera and am selling the old one so one purpose of this post is to provide information to a buyer who may not well understand IR photography. I’ve just finished posting on Istanbul/ Constantinople and next I will post on the Acropolis in Athens. (Some images have no corresponding posts, so no link).Ĭlick on any image to see it larger (If you are on a PC at least).
These are likely to be IR or Mono posts with little detail but there may be detailed information in a preceding normal-colour post.
