Robert Hart Posted July 3, 2022 Posted July 3, 2022 My understanding is that the ASA of old film stock needs to be regarded as one stop slower after ageing and over-exposed by that one stop to be assured of a recoverable image. If anyone has prior experience of successfully using expired 7217 (7277), 7248 and 7291, any advice will be appreciated. some folk who would like to shoot some old film on my older CP16R will likely appreciate it.

Robert Hart Posted July 6, 2022 Author Posted July 6, 2022 Robert Houllahan. Thank you for your response. The present scheme is to overexpose by one stop and request standard processing.
