*POLL* NOVEMBER PHOTO CONTEST Thread #2

[Major Nikon]

38. Neither is the vast majority of digital cameras

In fact, perhaps less so. B&W digital cameras do exist, but I doubt one was used to take any of these pictures. I suspect every one of these images started out in color and were converted to B&W. My IR camera is only sensitive to red, orange, and to a much lesser extent, yellow by virtue of the filter that's used inside the camera (590nm cutoff). A normal digital camera would be sensitive to the full color spectrum and would reject most IR light. So an IR camera (especially a true IR camera which mine is not) would at least be closer to monochromatic than a regular digital camera because much less of the visible light spectrum is being used. The picture in question was converted to B&W the same as all the others were, which is to say the individual color channels were desaturated to some shade of grey in order to produce a monochromatic image.

Back in the film days, the vast majority of IR photographic images were monochromatic.
