The EI will be determined by the developer it's processed in. You mention overexposure, but I wonder if the processed film exhibited high contrast too. In any case, if the film was processed correctly, and the only flaw was that it was overexposed, I'd ask the lab what they suggest the film be exposed at. Or, by extrapolation, you could use EI 50 if the film is going to be processed by the same lab. I would suggest that you process the film yourself, but I don't know if that is possible. It's a simple matter, and you then have full control. Allan Simon Lamb wrote: > I just had a roll developed by a lab and I > exposed it at ASA25.
