I'm looking to process some RA-4 paper, both for prints from color negatives and for use with in-camera negatives. A full RA-4 processing kit is quite expensive, so I was looking to put together a "kit" from more chemicals that I have around the house. I'll buy the Color developer, which is not too expensive. I know that standard fixer can be used, though it takes a little longer and gets depleted much faster.; so that's out. I also do not have a need for longevity at this point, as I am just experimenting, so that eliminates the need for stabilizer. For bleach I was thinking about using Iodine, as it seems to work for bleaching silver from standard B&W prints. Would this work at all, or am I completely off base?
