Overexposing film.

I just read that it may be desirable in older film cameras to set a lower ASA/ISO than actually being used.
As it is easier to work with (develop)overexposed film than the opposite.
The reason given that light meters may not be perfect.
Any thoughts.
Thanks.

The best way to know is to shoot a test roll with the given camera. Take identical shots of a subject both witht he "correct" exposure as indictaed by the meter and one deliberately underexposed. Pick a variety of subjects, light and dark. Then see what you get. Otherwise, it's just a guess.

He's thinking of overexposing, not underexposing, though the test would be similar.

I think this works a lot better for film, which compresses the highlights.

If in doubt, overexpose negatives, underexpose transparencies.

True to an extent, but not for the reason given, and only for print film.
Slide film doesn't stand much exposure error, and really doesn't like being over exposed at all.

you 'over-expose' negative film to capture shadow detail. You develop your film so as not to 'blow out' the highlights. This is the basis of the 'zone system'. There are some tests (film speed test & normal development test) to determine your personal EI for a film and 'normal' development time. Film speeds are determined using a test in lab, not the real world. Although the zone system is more relevant to sheet film, determining your film speed and development is still a good idea for roll film users as you'll end up with negatives that are easiler to print (and scan if that's what your doing). After all, if it's not on the negative, you won't get it onto your print!
