Bob, et al,
I'll toss in my two cents worth here. It was explained to me that the low
temperature didn't actually increase the sensitivity of the film, but rather
reduced the effects of reciprocity failure. Kinda the same thing in a way
if you gotta use looooooooong exposures. But that would mean that the
effect would not be as dramatic with films such as TMY and TMX 'cuz their
reciprocity doesn't fail quite so badly.

A cold Camera lowers the temperature of the film. This seems to increase
sensitivity. Also, a search through any of the popular astronomy magazines
will turn up a number of companies offering hyper sensitized films.
