Film Processing
When using conventional films, you must process the film according to the manufacturer’s
instructions. Process the film under safelight conditions manually or using an automatic processor.
If you use an automatic processor, see the processor’s manual. Check that the processor
maintenance is performed regularly.
If you process the film manually, follow precisely the manufacturer’s recommendations for solution
preparation, processing time, and solution temperature for both the developer and the fixer baths.
Any deviation from the manufacturer’s recommendations (such as a solution that would be too
concentrated or diluted, too hot or cold, or if the film processing duration is incorrect) will impact
the final radiography quality.
Before archiving, do not forget to wash the film correctly and to dry it in a clean place.
