The only place I use shortstop now is immediately after the Color Developer and before Bleach-Fix in color printing. Developer holdover - even after a water wash, is simply too great for me in RA-4 printing.

Check Ilford. Last I knew, they were NOT recommending the use of an acid shortstop in black and white film developing (due to the danger for pinholes), substituting a water wash instead.

I've heard those who complain about the odor of acetic acid. Possibly a more dilute mix than the standard - 16ml per liter of water would be less offensive.

Come to think of it ... I once used common white vinegar diluted 1:4 to 1:10 instead of the expensive photographic stuff.
