- Well, all stop bath does is neutralize developer, whereas a water bath
- simply attempts to leach developer from the print. The fix is an acid
- as well, and can likely neutralize any developer that remains after the
- water bath. Another plus to a water bath between dev. and fix. is that
- there's one less chemical to wash out of the print.
- And unless you're using that special paper (can't remember the
- name of it) that will keep developing until it's black, there's no
- real need to have development stopped instantly.
