what does c 41 Bleach starter do
I need some help clarifying an issue I have.
I know some C41 bleach products are available pre mixed and ready to use (kodak Bleach NR) and some (Kodak Bleach III) require a starter added to a replenisher to make a tank solution.
I acquired some bleach that is similar to the latter Bleach III that requires starter) that is made by Silver Pixel and the limited info I can find says a starter is required.
What is in the starter and is it necessary? Even the Kodak bleach starter is hard to source and I'm hoping I can get by with just a replenisher solution.
What does the starter add/do that facilitates correct bleaching in C41 process that would be absent in just the replenisher?
As always, thank you in advance for any help you may be able to supply.
