Black and White Film Processing
DURATION - 2 HOUR
12 STUDENTS MAX
ROOM - 3B17
NO food or drink to be taken into the film processing room.
Keep tidy: put bags and coats under the table so you can’t trip over them in the dark.
The chemicals are harsh irritants: if you ingest them or get them in your eyes, speak to a member of staff as you may need medical attention.
There are disposable aprons and gloves to wear for your protection. Wash your hands after you come into contact with the chemicals.
Keep wet items away from the dry bench.
Equipment you will need:
A film retriever (if the film leader is not visible).
A metal spiral for each roll of film and a metal cage. Check these are both completely dry.
Things to check before you start to process your film:
Use the film chart to see how long to process your film if the developer is at 20C.
Measure the temperature of the developer.
Use the chart to adjust the time of development by the actual temperature of the developer.
Wind the clock (2 winders) and set the minutes.
To process your film:
If the film leader is not visible, use a film retriever to pull it out.
Cut the leader off.
You can start to load the film onto the spiral in the light.
Turn off the light, load the rest of the film and then put the loaded spiral into the cage.
Developer time: depends on developer temperature and film type.
Agitate constantly for first 30 secs. Stop for 30 secs then agitate for 10 secs.
Wait for 30 secs then agitate for 10 secs. Continue this cycle until the end of the dev time.
Stop time: 30 secs, agitating constantly.
Fix time: 5 minutes. Agitate for the first 2 minutes.
Wash: 20 mins.
Wetting agent: 30 secs, do not agitate.
Hang the film in the drying cabinet. It will take 1-2 hours to dry. Please remove the film from the drying cabinet as soon as it is dry, to make way for other people’s film.
Please rinse the cage and spiral in the wash when you have finished processing, so you don’t contaminate the developer.
Fill in how many rolls of film you have processed on the chart in the processing room.
When your film is dry, cut into strips of 6 frames and keep, ready for printing, in a negative bag.
