Film test setup

[Steven Ruttenberg]

Thought easier to start new thread. Tmax100 to be developed in Tmax Dev at 1:8 for standard temp of 68F and time of 7:30 (same time as 1:4)

Images are the set up.

The lens is 210 G-Claron.

Card measured 7ev, so for Zone 3 that would be ev 9.

Starting at f11, will stop down 1/3 increments until I get to f/16. This should be simulating iso 50 to iso 100.

Shutter speed is 1/4 sec. I am using my analog Pentax spot meter to determine settings. So if I change meters, I need to make sure it is behaving like my Pentax.

Minor catastrophe. While getting ready the wind kicked in from nowhere blew easel over and like domino's took out camera. Luckily, I think it will be fine. But after tests sending it in for repair.

Test shots done.

Metered dark card final was ev 7 so for z3 would be ev 9. Started at f/11 and went to f/16 in 1/3 stop increments hold exposure time constant. Repeated for white card. Metered ev10.6 for zviii ev is 7.6. Started at f/11 then to f/16 holding time constant at 1 second.

Had to double check everything. Almost screwed it up. Soon as I get my thermometers back from calibrations will develop.
