Hi All, I have a question with regards to using a stop bath for RA-4 print developing. Are there any issues with using a stop bath normally used for B&W prints (e.g. Kodak Stop Bath with Indicator) for RA-4 prints? In other words can I use the stop bath for B&W and colour or should I mix a separate batch for each type of print. I'm worried about amassing different chemicals and the effect it may have on the final print. You input would be appreciated.
