Has anyone
ever tried them for flim photograhpy?
I saw white LEDs used as lighting for macro
photography. Though with digital cameras. Most white LEDs are weak on the red
side of the
spectrum. Sometimes this gets mitigated by adding extra red LEDs.
I would have thought the problem with doing that is that the red LED
output is a very narrow band of wavelengths. It may not compensate that
well on colour film
I guess the thing to do is to try it. OK, sometime when I've got some
spare time I will pay around with various LEDs, a camera and a grey card.
