A buddy of mine bought a stereo camera that was made from 1955-1959 and it's got an exposure chart on it based on Kodachrome K335 stereo film and he's not having much luck coming up with what the speed of that film was so he can use the exposure chart. I was hoping someone might know what it was.
The 335 Kodak film was 135 with the designation to tell Kodak to cut and mount as stereo pairs. Some sources say the leader is also trimmed a little differently. It is my understanding also that it was ASA 10, thus the red detents are pretty useless and with slide film one really should use a meter anyway. I have the first roll of Velvia loaded in mine.
