IR Photography

[asterroc]

I tried out some IR photography this weekend (after a post on UV photography by txtriffidranch the other day). In the sequences below the cut, I have three images: normal visible light (technically, representative false color), a black and white version of the visible light image, and an IR black and white version. (I used an IR filter which blocked out all but the reddest of visible light and of course didn't block IR. Digicams are sensitive to a bit of the IR spectrum, so it sensed both the red and the IR and that became the image). If you want more explanation of the phenomena, I posted on my science blog about it.

Wow! Really startling changes -- and continuities! The second set, with the trees and sky, is particularly striking. Beautiful pictures!

I exploited CCD sensitivity to near IR at work, to track a 1060nm laser beam whose spot was invisible to the naked eye. It came out purple on the camera's LCD screen and in photographs taken with the camera, for reasons I cannot explain. (This was not using an IR filter, because we also wanted to see the surroundings)

IR photography is fascinating. Of course, light itself is fascinating! :)
