I ran a test roll of the film to see about speeds, etc. I rated it at iso 6, which is as low as my meter goes, and shot a roll at 1/4 sec, f32, 22, 16, 11, 8, 5.6, 3.5
and developed in Rodinal 1/25 for 10 min at 67f.
The only decent negs were at f32 and 22. This equates to three stops below iso
6.
Since I plan to shoot landscapes, and use at least f 11, perhaps f 32, I am concerned about reciprocity.
Oh, and I used an IR filter, R72. the meter read Ev 10.5 which I put on zone II. the subject was trees and bushes in my back yard, high reading was 15.
the efke site does not speak to reciprocity, near as I could see. The massive dev chart says 9min in 1/25 Rodinal, so I am reluctant to get rough with the developer.
Any thoughts on this?
