So I now have 2 oneshot tricolor cameras. And I really would like to use them (at least once to prove it can be done). So I'd like to get a sensible idea about exposure for this.
The camera splits the incoming light in 3 paths going to 3 negatives: each one gets 1/3 of the light so that is (1 + 2/3) stop loss. Correct?
Each negative has a filter (25, 47B and 58) and those have a factor of 2.5-3. Again this gives a loss of (1 + 2/3) stop. Correct?
So as a start I should compensate my measured exposure (3 + 1/3) stop or multiply exposure time by 8 to 9. Correct?
I know this is probably only a very rough approximation but I do not have much film in the size needed, I need to get started somewhere.
