E-6 COLOUR PROCESSING (Part 2)
FIRST DEVELOPER
This is basically a kind of a black and white developer, if you were to fix at this stage you would have a B& W negative.
COLOUR DEVELOPER
This couples in the dye layers of each colour with in the film. Think of colour film as a sandwich of different layers of colour through which the light passes through, when
placed into the colour developer it binds all the colours together in the final image. Also incorporated is a chemical reversal which changes the film from a negative to a positive image.
BLEACH /FIXER
This does exactly what its name suggest it removes the unwanted dyes and unexposed silver particles in the film and reveals the coloured image in the slide. If the film was viewed before this stage it would look very much an unattractive strip
of brown tape.
To begin processing, first mix the required amount of chemicals and place them into the water bath and bring up to the processing temperature of 38°C (the water bath should be set at two degrees higher than this). Load your film into the developing tank in the usual way and then prepare a two gallon bucket of hot water at 42°C this will be used as a preheat bath and serve for rinses between each chemical . Other items you will require is some wetting agent to be added to the final rinse
as a conditioner and a few cloths to wipe any drops water as you lift chemical containers out of their water bath.
The first step is to bring the tank up to the processing temperature. you can do this by placing it in the bucket of water for 5 minutes or pour in clean water at 42°C and leave for minute, this will bring the tank and its contents up to processing temperature. On pouring out the water you may note that it is coloured this is normal.
Pour in the FIRST DEVELOPER and agitate immediately
for 10 seconds then at intervals of every 30 seconds for 6 ½ minutes. Pour the developer back into its container and save. Wash the film with clean hot water for 3 minutes making sure that you change the water several times during this stage.
Pour in the COLOUR DEVELOPER and agitate as above for 6 minutes, pour out and save. Wash the film again for 1 ½ minutes with several changes.
Pour in the BLEACH/FIX and agitate for 1 minute then every 30 seconds for 10 minutes, pour out and save.
Wash the film for 4 minutes with several changes of water, on the final rinse a few drops of wetting agent can be added. And leave for 1 minute. take out the film and hang up to dry.
CONGRATULATIONS YOU HAVE NOW PROCESSED YOUR FIRST SLIDE FILM.
