Film & darkroom
A film processing log you can actually use
Connect exposure, chemistry and the finished negative in one record.
A useful log answers a future question: which conditions made this negative? It also helps a laboratory or another photographer understand a problem. Begin the record before the session and keep it with the roll identifier afterward.
Before the tank
Our log begins with roll identifier, film, format, exposure index and capture notes. Add the exact developer, dilution, working volume, recipe source and starting temperature. Record the tank and agitation method. Leave separate spaces for planned times and actual times so a deviation cannot quietly replace the original intention.
During and after processing
Write the stop, fixer, wash and final-rinse details appropriate to the documented process. Note any interrupted stage, uncertain label or temperature drift. After drying, record edge markings and the appearance of the whole roll before judging an automatically adjusted scan. Photograph a representative result without discarding the negative.
Keep the record connected
Name the scan folder with the roll identifier and put the physical sleeve location in the same record. Keep edits and printing decisions as later entries rather than changing the capture or processing history. For our comparison worksheet, vary one planned condition at a time and explain the question the next test is intended to answer.
