Hi all!
I was shooting stars recently on a mountain top, with a temperature
of around -20c. And then I wondered...
Does low temperature have any important effect on film sensitivity?
How can I compensate accurately for that?
Funny enough, my OM2000 handled the freezing pretty well
(actually better than my fingers) while my friend's electronic
Minolta got a frost bite and only worked half the time.
I was also wondering... (this might be a stupid question)
Since stars are quite close to true point light source,
could we use them to evaluate the resolution of a lense?
