Just to clarify, I understand how to compensate for bellows extension and how to compensate for reciprocity failure. I'm seeking guidance on how development time needs to be adjusted, if at all, where either or both of these occur. My understanding is that (i) increasing exposure time to counteract reciprocity failure will result in increased image contrast and (ii) reducing development time will offset that increased contrast. I'm trying to understand that relationship.

Ian, thanks for the PM, it was very helpful.
