For those of you processing RA-4, I'm curious, do you use the blix one shot or do you reuse it (with or without replenishment)? The Kodak docs and other resources suggest using all chemicals one shot. But then I've seen threads here suggesting that one benefit of using an intermediate stop/wash with RA-4 is that it makes the blix last longer -- which suggests reuse. For my 8x10 paper processing, I can use 60ml of solution one shot, or mix a half liter and use it for eight or nine prints. I'm using a drum on a motor base. I hadn't really considered an approach that involves replenishment, but I'm open to ideas. Curious to hear what others are doing...
