From: Scotius on 15 Jul 2010 20:48 I know that color infra-red images look really weird (for lack of a better term), but I once read that infra-red light cuts through fog/haze etc better than regular light, which I suppose is why B & W infra-red shots always look better than B & W shots without IR flash. So I'm wondering if there's a program that could accurately predict based on IR color what the colors present should be, and convert them, so it would be possible to do color shots better in haze, etc. Anyone know of anything like this?

Unless you know the precise IR spectral response of every material in nature or man-made, and were certain those exact same materials appeared in your scene, it would be impossible to convert the IR frequencies to known colors in the visible spectrum. Take for a simple example two green paints. One highly reflective of IR, the other highly absorbing of IR. If you shot an IR image of a green-painted object through the obscuring haze from a fire what color would you try to redefine it as? IR works great for shooting through the haze of immense forest-fires. I have quite a few majestic scenes and large panoramas of forest-fires in front of towering mountains and glacier-capped peaks, abnormally hidden from view by the dense forest-fire smoke but clearly revealed in IR. Unless I had similar images taken from the same locations at the same time of day during the same season of the year without the smoke present, I would be in error trying to convert the IR-luminosity spectral response of those hidden portions of those images to their full-color counterparts.

I can't see how it might work. The color information you are looking for is not in the data you have. I would guess it may be possible to make the results look a little less odd, but I doubt that it would help any. It would be something like trying to make a Big Mac taste like cheese cake with cherry topping with out having cheese or cherries or even knowing that what you have to start with is a Big Mac.
