RA-4 all the way: I do the following: with Kodak dev/repl RT (roller transport) I mix as specified, then dilute that 1 + 4. I process paper at ambient (80F) for 2 - 3 minutes. I develop color film (at 105F) from 12 minutes (for ISO 100) to 16 minutes (ISO 800). I store the chems (either diluted or not) in clear, plastic soda/juice bottles) and if filled to the very brim, never expire (despite what admonishment might transpire with that statement). It works for me and will work for anyone. That is the most hassle free way to process color. Everything I do is 'one shot'. Color dev is very capable of such dilution and what 'fails' first is not the exhaustion of the developer but, rather, the presence of bromide that the film gives off. With color development a tiny bit of bromide slows things down tremendously, unlike with the more attenuated effect with BW process.
Also, I do not use or buy the BLIX. I use regular or even more diluted stop bath, then fix, then use a solution of potassium ferricyanide for the film (1 gram per 20ml water). That clears the film nicely in about two minutes and you need only enough to evenly coat the film (just use wetting agent); as this bleaching is a process 'to finality' you do not have to worry about unevenness. (NOTE: if you want slightly more contrast omit the bleach, as the color coupler plus the silver already there will add to the contrast.) Then a brief fix again (same fix) for about 30 seconds, then wash and dry. For paper, similarly, I stop and fix, then into a potassium bromide bath (this time far less potent than for films: only 1 gram potassium ferricyanide in 100ml water. That for about 1 minute, then, again fix (same fix) for about 10 seconds. Wash and dry.
I cannot come up with a more economical way to do this. The ONLY 'color' chemical involved is the dev/repl RT because the potassium ferricyanide is also a BW chemical. I buy from pdisupply.com in Rochester, NY.
