However much fun it is to mourn the old films we have lost,
the the films which replaced them are better. Here are a selection of Kodak MTF and Grain/Granularity charts for your entertainment.
If you aren't comfortable reading an MTF chart, you might look at where the curve crosses the 50% Response line (vertical axis) to see the practical limit of that film's Spatial Frequency. This is a handy snapshot of what the film can give you.
For instance, Tri-X gives you 60 cycles at 50% contrast. It has a Granularity of 17 (fine). TMZ gives you 80 cycles at 50% contrast. The Granularity is 18.
There are two questions one might ask. The common one is, " Kodak doesn't know what it is talking about"; the second is, "Hmm, I wonder what I can do to improve my pictures ?".
Take squint at TMY2 & Verichrome Pan; and if you feel strong, compare TMX to Tech Pan and Panatomic. For that matter, take a long, hard look at TMY2 and Panatomic X.
Have Fun ! :munch:
