That logic is impossible to question, but it may also depend on what the 
detail is, and who's looking for it. I've seen evidence for both cases.

Some old photos, shot with very slow lenses and even slower film, show an 
incredible amount of detail. Some modern high-contrast films, even when shot 
with the best of lenses, seem to blot out the differences. Are the details 
there? I don't know. I can get them out of "slow" film with a scanner, but 
often not out of "fast" film without a lot more work. My thinking is that 
the detail is *there* but not readily accessible. And probably, sometimes, 
it just isn't there at all.

What's a mother to do? ;-)
