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.

How far into the UV can birds see?
I'm quite intrigued because UV has enough energy to break a number of chemical bonds, so anything that is not near the visible light region would blind the viewer.

Now that I don't know, but I'm sure you can find papers on it. :) Let me know if you do look for it.
