What should I check first on a blank film roll?
Look for the manufacturer edge markings. No edge markings can indicate that development did not occur; normal edge markings with blank frames usually point toward exposure, loading or camera operation.
Are thin negatives always caused by development?
No. Thin negatives can come from underexposure, underdevelopment, weak chemistry, low temperature or an incorrect development time.
Can a scan prove who caused a film problem?
Usually not by itself. The physical negative, camera behaviour, storage history and processing records must be considered together.
