10 is a lot!

I tried doing separate bleach+fix on RA4 using the Kodak chemicals and the bleach didn't work. It seems to need a buffering agent or something (acetic acid?) from the fix part to change the pH in order to bleach properly. If you bleach then fix, you will get retained silver, low saturation and high contrast. It's a nice look for some things, e.g. if you have a flat scene with lots of texture. Damn near impossible to get a flattering portrait from it though!
