      Fred, the only films that can even come close to today's sensors is Tech
      Pan and Kodachrome, With K a distant second to Tech Pan.




I know, Larry, but if the temperature is too low to allow a digital camera and its batteries to function, a Nikon FM2 (or any other fully mechanical camera) with an 8mm full circle fisheye attached would romp the project in (even if one had to open the shutter in a warm place first and control the actual exposure with a lenscap should the lubricants freeze and seize the shutter).

I wasn't suggesting that this should be what we regress to, merely responding to Ann's observation of noise occurring in very lengthy exposures in digital cameras. I haven't yet tried an exposure running to hours to confirm that this indeed will happen with a D3, only commenting on that supposition as put.
