Slovenian cave salamander-based photography medium

Use olms to take photos
  [vote for,

Olms are white cave salamanders which live in the Balkans. On exposure to light, they gradually turn black. I suspect, though, that they turn completely black and wouldn't respond to individual patches of light.

So, i suggest that olms be collected and placed in fairly small chambers, though not so small as to constitute cruelty, then a lens be placed to focus on an array of fibreoptic apertures. The object to be photographed is then very brightly illuminated over a period of several weeks, and light shines into the different chambers to different degrees. The olms then become differentially tanned and can be observed through peepholes illuminated by infrared lamps, linked together once again by fibreoptics into a grid. Result: a relatively cruelty-free photograph and a reason to Save The Olm.

       Sorry, i didn't express it very clearly. Thanks, [FT]. Actually, that's slightly different than what i meant but would work better.

       well, I was thinking of posting an alternative motion/stereo sensor, had it all worked out then realized it was insect-eyes, so that' s where my brain was at.   

       I take it your "film" is a wall of pigeonholes, each occupied by a lizard, and a multi-planed lens on the aperture to focus one pixel onto each lizard.
FlyingToaster, Oct 21 2009

       Yes. I think to guarantee animal welfare, some research would have to be done on how much space olms are comfortable with. Maybe monitor adrenalin or other stress indicator according to how much room they have. The trouble with that is that maybe light automatically stresses them.   

       By the way, note the pedantic links.

       Yes, deeply groovy animals and an obsession of mine during my childhood. Incidentally, there's a black race which would not be useful for this purpose.

       So the image is depicted on the olm? I think there are other more common animals one could pilot this scheme with , for example octopuses. Or the white and untanned belly of a halfbaker, once adequately washed and shorn of hair.

       No, they aren't big, but there's a local folktale that they're the larvae of dragons. Twenty to thirty centimetres. [Bungston], each olm is a pixel. However, it could work with us lot to an extent, depending on our ethnicities.
