Back in the "old days" . . .

Many a skilled photographer acquired secrets for extending the DR of film. One was pre-soaking the film in a disproportionate developer and then under developing. A real bitch to print, but the info was there. Of course pre-flashing the film before normal exposure was another. The list goes on. AA (and others)spent many years perfecting these techniques. Hence, the Zone System began and continued on to various printing techniques (the REAL problem child).

Generally speaking Tri-X was known for it's incredible DR and long toe. Again, a bitch to print. I am not sure what a film densitometer would measure, but I would guess 11 stops would be about max. My D200 can do that with a 16 bit double conversion.

Now if we were to compare my favorite slide film of old, Velvia 50 or 100, the D200 wins - by about 4 stops!

For four years I developed about 10 rolls a day, 5 days a week (sports and news). And that's not including MF and sheet film. Then I changed jobs and only did 20 rolls a week (glamor and products). Figure 50,000 rolls over a 40 year period! Now you know why I LOVE DIGITAL!!!! :^) Love it, love it, love it. Don't talk to me about film!
