I played around with my Leica Digilux Zoom (spent all my ducats on an M7 so I have to wait a while for the 'biggie'digital!) and found that by eliminating all but the red channel- that I had a nearly IR photo. I imagine it was pretty close as the CCD is sensitive to IR in that I looked at the IR LED on the VCR flinker, and the otherwise invisible beam shows up as a pale blue in the Digilux viewfinder. I would be interested to know what the full spectral response might be as the IR effect of shooting and keeping only the red information works pretty well. I did try shooting through a Leitz IR filter (looked about the equivaent of an 87C- very deep red- and of course got zip, zilch, nada for my effort. :o( If the future is digital, think of the possibilities of shooting in the UV and Near UV spectrum, and taking IR photos as a regular course--- I am pretty sure that folks like astronomers already do this with the CCD devices they use- The Three College Observatory near here has published some really neat timed exposures (5 minutes!- sharp with no camera shake!) of deep space objects outside the visible spectrum. I guess they are 'false' color, but they are simply beautiful. I can see why amateur astronomy is so popular!
