Step by Step Guide
- Pour Collodion onto a glass or tin plate. Cover the whole plate and drain excess into a separate bottle.
- After Collodion has set, place into the silver bath for 3 minutes.
- Remove plate from silver bath and dry the back of the plate. Do this under safelighting (usually red). The plate is now light sensitive.
- Place the plate into the film holder and expose in a large format camera.
- Return to the darkroom and develop the plate for appr. 15 sec. The plate is not sensitive to light anymore.
- Pour water onto the plate to wash off the developer as quickly as possible to stop the developing process. The developer is washed off when the greasy/oily look disappears when you stop pouring water.
- Place the plate into fixer bath until all white spots disappeared.
- Wash the plate intensively in running water.
- Dry overnight.
- Next day collodion side covered with asphaltum.
