I used to have this problem with scope photos. The shops would always
leave the machine on automatic, which 'ac couples' the exposure level
to a uniform average; all the shots would come out grey. I had to tell
them MAKE PRINTS DARKER THREE STOPS to see anything.
Now I use a digital camera and I'm much happier.
