I use the standard X-ray film at work with green bioluminescence directly
in front of the film. For luminescence I cannot see in the darkroom, this
film can sometimes reveal a signal in less than 10 seconds. In my thinking,
I liken the luminscent bands (they are from electrophoresis gels) to
something faint like Andromeda galaxy. If as you say, it really is not very
sensitive, perhaps it could still be very useful for images of brighter
objects, such as the Sun, Venus, Moon and Jupiter. I will think a bit
further on this and try some test pics.
