Anderson method for increasing C-41 saturation?

[ChrisBCS]

Hi all, my fiancee has been nudging me to try shooting/printing some color with my MF. I'm obliged to give it a try seeing as I have a fully functional dichroic enlarger. The only color I've ever developed or printed is Velvia/Cibachrome many moons ago. I love love love the saturation of Velvia.

I had heard about a method called the Anderson method but haven't turned up much about it. It apparently involves fixing in B+W fixer, bleach in potassium ferricyanide, then redeveloping in C-41... I'd like to find the original article that explains this photochemistry, or hear anyones' experiences using this method.

Many thanks

It appears this method runs C-41 film through CD, then fixes away undeveloped silver, then rehalogenates the developed silver and runs through CD again. Result is increased contrast and density which may show up as increased saturation.

The bleach for this process must also contain Potassium Bromide, Potassium Ferricyanide alone won't do it.

Chris, is your end goal to produce RA4 prints? If not, it is possible to use a hybrid process by scanning the negative, postprocessing and printing digitally. Can't go into the detail here because the site has a non-digital policy.

if anything, Ektar and current RA4 printing papers have TOO MUCH saturation already. I doubt you would need to do anything to get more.

I have done this with ECN-2 film with good results, but with increased sharpness and grain, as well as increased saturation. It is a good way to get ECN2 to more closely match the contrast characteristics of color printing paper.

This is called rehal processing (rehalogenation) and is used widely in R&D testing and in the trade for higher contrast. Giving it any other name is rather amusing to me as it is so well known.

The OP by his own admission is unfamiliar with color negative processing yet he wants to start with a specialized technique. Frankly this makes no sense -- start with the basic C-41 processing. Later on there will be time to experiment.

I recommend learning to do it correctly first and develop several types of film before you start experimenting. Otherwise we get an endless string of threads with experimenting and asking about what went wrong when the OP does not know how to do it correctly and has no idea of what they did correctly or in the wrong way. It is just a WOMBAT ===> Waste Of Money, Brains And Time. But not so much on the brains side.
