LAB-BOX: Colour Film Developing

Picture
Lab-Box and 35mm film spool.

For colour developing I use the CineStll C-41 chemical kit to make 1 litre.
I mix the packets of powder as instructed and store them in 1 litre black opaque bottles to protect them from light and deterioration.

It's important to keep the chemicals quite separate, so I mark each bottle with coloured tape and write the name of the liquid on the tape. Yellow tape for Blix, red tape for Developer. 

As I use the chemicals, I make a note of the date and how many rolls of film.
There are instructions in the C-41 kit, outlining how many rolls of film that the 1L mix is good for.
After that you must discard it and make up another batch.

Film is now light safe.
Remove lid from tank.
Remove film spool side section so you are just left with the tub section.
Run cool water over the film for 3 mins.
Pour out water.

If you have another film roll to process, put completed film spool into a separate jug to run water over. Then you can begin processing the next film in the Lab-Box while the water is still washing the first film.

After washing, cover the spool/film with clean water and add stabiliser (wetting agent).
500ml water + 2 drops wetting agent.
Turn knob 30 secs
Leave to sit 30 secs
Pour off.

Attach hook clip to top end of film and other clip to bottom end and hang up to dry.
