This is weird: I had a bunch of google hits today (thanks linkers!) and one was for '"piece of mine" outkast' which refered to a quote I used to announce Carter's Nobel Peace Prize. Also in the search were two other spontaneous uses of that quote [1] [2] - also for cynical reasons - within a couple of days of my own quote. Weird.
New photo by Heather McLaughlin.
Still taken by the stunning and subtle color of the digital ir photos, I decided to do a little research. I had clues that the Nikon's ccd represented infrared as false colors, so I photographed a spectrum of a light bulb, which is rich in infrared light. That spectrum is the lower of the two in this picture:
To see the spectrum used in the ir photos, I applied the transmission curve for the 89B filter (obtained from the Tiffin Photar Filter Glass Catalog, 1978, Tiffin Mfg. Corp.) to the spectrum of the lamp with Photoshop.
The upper spectrum is the result of masking the transmission of the infrared filter onto the spectrum of 'white' light. To my eyes, these colors do look like the range of colors in the ir photos.
Der Schockwellenreiter points to this readable and well illustrated History of Photography. Very cool.
