Frequently Asked Question
Why is there a time listed for one film size (eg. 35mm), but not another?
Last Updated 4 years ago
Some manufacturers publish different data for different formats, others don't. User submissions are always specific to the film size, and don't usually cover all sizes. In every instance, if no time is listed for the format you are using, then use the time listed for another size as your starting point. In practice, the vast majority of film can be developed for the same time regardless of the format.
