Processing film

Daylight developing tank 

1. Firstly you have to use a film retriever to extract the film. Then open the top of the film with a pair of scissors inside the double layered change bag.

2.  You need to put the tank body, centre column, light tight funnel lid, plastic cap, film and spiral inside the change bag.

3. Pull all of the film out of the cassette and feed the end of the film on to the spiral. This requires a little patience. Try not to get your finger tips all over the film as it shows up when printing. The spiral has 2 large on the inner side of the plastic and 2 small notches opposite. Align the two larger notches and pass the film just under those notches. Hold the spiral in your left hand and place your first and second fingers on top of the two large notches and turn clockwise and with your right hand twist anti clockwise  very slowly (remember this is in the dark) until all the film is in the spiral.

4.Slide the spiral containing the film on to the centre column and add another loaded or empty spiral on top. The column  must be full before placing the connected spirals into the tank body. If you only have x1 film, make sure the film is on the bottom spiral to ensure it is processed when chemicals are added later.

5. Once the centre column and spirals are positioned within the tank body, secure the funnel lid by twisting and locking in to place. At this stage it is always a good idea to hold the tank by the lid to ensure it doesn't come lose.

6.Your film is now in a light tight container and ready for the chemical process. Do not remove funnel lid until all stages of  development are complete. Any exposure to light will destroy your film. 

               When processing two films you have to use x2 the amount of chemicals.
