inframisc.
Some recent experiments with "color infrared". Which involves taking a regular IR photo in a color mode rather than the usual monochrome, which gives you an all-red photo, not that interesting at this point. Step 2 is to have GIMP try to auto-correct exposure and white balance, which leads to the lilac-colored trees and orange sky you see here. The fact that the colors are consistently this way suggests there's some physical basis behind the color differences (although not the colors themselves, obviously), but I have no idea what that might be. Step 3 is additional tweaking to exposure, color saturation, etc., as needed, until it looks nice. Or at least until you feel you've had some manual input into the process, I guess.
