Answer: shorter/longer developing time.
Explanation:
Ideally, the time to process a radiographic image in the developer is 680 F for 5 minutes. But films may be removed from the fixing solution after 5 minutes (and fixed back) for viewing, only at emergencies like if the temperature of the developing solution is slightly above normal.
If the temperature of the developing solution is slightly above normal, the radiographic images of the required density may be produced by permitting a shorter/longer developing time.
