Processing Black And White Photos
1. Hanging Clips, Squeegee, Goggles Thermometer, Tongs, Trays, Paper, Safelight, Liquid Measurement tools, Film processing tank, Clock/Timer and Devices
2. Developer, Stop Bath, Fixer, Wetting Agent
3. Process:
- Prepare Equipment:
- Turn the light off.
- Load film onto reel and assemble tank.
- Turn the light back on.
- Prepare chemicals.
- Pour in developer, start timer and agitate for 30 seconds.
- Check temperature and calculate development time.
- Agitate 2 or 3 times every 30 seconds until end of development.
- Pour out developer and run tank under water for 30 seconds.
- Pour in fixer and agitate for 30 seconds.
- Check film is fixed after 3 minutes (clear=OK, milky=more fixing needed)
- Pour fixer back into bottle when fixing is complete.
- Wash film for 15 minutes, emptying tank every 5 minutes.
- Dip film into wetting agent for 30 seconds and hang to dry.
- Cut up and sleeve film for printing.
Define:
- Contact sheet-a photographic image produced from film: sometimes from a film negative; sometimes from a film positive.
- Agitation-
- Enlarger- a specialized transparency projector used to produce photographic prints from film or glass negatives using the gelatin-silver process, or transparencies.
- Developer- a chemical, often a mixture of metol and hydroquinone, which converts the latent silver halide image in the exposed photograph material into reduced, opaque, black silver metal
- · Stop Bath- a chemical bath usually used in processing traditional black-and-white photographic films, plates, and paper used after the material has finished developing.
- · Fixer -a chemical that removes unexposed silver salts from photographic media and renders them insensitive to light.
