Can a film with a lower ISO handle a louder sound without clipping than
a film with a higher ISO? I ask because I get the feeling that if there
grains are finer, the film can record more levels of amplitude -- just
like a 16-bit audio file can handle 65536 loudness levels while an 8-bit
audio file can handle only 256 loudness levels. I could be very wrong
though. Not sure if this is a good analogy at all.
