    Colour Infrared

    I’m in the process of re-creating the KIE look in digital.

    I have an Olympus OM-1 that I’ve converted to full-spectrum, with a bunch of in-body clip-in filters (from stcoptics.com) for various frequency cut-offs.

    I bought a “protection filter” in the clip-in format, and am planning to mount various yellow filters on it. I have a 25mm diamond hole saw, which will make the size needed by the clip-in filter holder.

    At that point, I’ll have infrared in the blue channel, and IR+red and IR+green. I’m planning on using ImageMagick to do channel subtraction and re-assignment, so that IR will be magenta, red will be yellow, and green will be cyan.

    Then I won’t have to worry about digging ancient film out of the freezer to get my KIE fix!
