So we got BetterLight at 11 stops of brightness
A Good Digital camera at 8 stops
A cheap digital camera at 6 stops
How many stops can a B&W negative hold? (At rated ASA)
How many stops (max) can one print out with chemical
development of a print? (glossy? matte?)
Probably 5, glossy
How many stops can a Color negative hold? (At rate ASA)
People were taught 10 or so.
How many stops of brightness can a slide hold?
Maybe 7.
(These numbers were "common knowledge" 30 years ago, which means they
may be nonsense.)
