    Color Infared

    I know there is EIR and Aerochrome, but surely there has, in the past, been other companies that do it? Has there ever been a Color IR c-41 film? Because that would have been amazing. Why are all the color infared films I've heard about chromes?

    I've always understood that the Kodak Color IR was designed for specialist military/aerial/scientific work, where the "false color" rendering enabled sources of infra-red and objects/plant diseases, etc., to be more easily identified. The packaging as 35mm for amateur and pictorial use was maybe something of a sideline?

    I wonder if a C-41 IR film would have enable this object identification, etc., to show up more clearly....if not, there would not seem to have been an obvious use for it? But maybe there was such a film for specialist use and it was not packaged for general sale? Or perhaps the B&W IR negative covered what was needed?

    Of all the false-colour IR films there was none designed for C-41. Though there have been negative films.

    EIR cross processed gives amazing results. Sometimes the tone scale is reversed but the colors are normal and other times the tone scale is normal but the colors are reversed.

    Kodak Aero Ektachrome was used in forrestery to identify if trees were alive or dead, and for military aerial recon. to see through camoflage.

    Ben,

    It was rather intended at distinguishing between camouflage and real plants, not to see through camouflage.

    Well, actually, modern IR films could see a hot truck through some camoflage or could see places in parking areas where hot trucks were parked. You are both right depending on situation.

    But you would need a lot of darkness and a lot of patience too...

    (But there are electronic sensors which can do so under practical circumstances.)

    I would think that the reason it was never made as a negative is that because it is "false color", there would be absolutely no way to calibrate the print color. You couldn't shoot a Macbeth color chart with it and then compare the print against the Macbeth.

    Kodak still makes Aerochrome which is color infrared E-6 film. They only make it in large sizes, but there is a guy selling it rolled up into 120 on ebay and on his website.
