Figure may as well post a thread instead of hassling someone with pm's again.
I wanted to ask something quickly in response to a thread starting hydrogren peroxide will give black slides in a colour reversal process.. is it because it forms colour through silver after the fact?
ie: If you take a colour film, develop it, and fix it, then place it in colour developer with hydrogen peroxide added, colour will continue to form through the silver as a mask upon the rate it forms dye?
I've also seen mentioned use of 3% hydrogen peroxide (supermarket stuff) for added contrast.. and I was wondering if people typically use a whole bottle/couple hundren ml or just a few ml for a noticeable increase in contrast in RA-4 or C-41?
My google-fu doesn't find any results of how much people are actually using to get a result.
