This appeared to do a very good job of taming the highlights. I've been experimenting with T-Max and Delta films in XTOL between 1+2 and 1+4, and D-23 1+2 with a second bath along the lines suggested by Anchel and Troop: a modest amount of alkali, some sulphite as a preservative for the carried-over developing agent and 30 g/litre salt to reduce swelling. A&T, along with others, suggest that sulphite should be kept below 35 g/litre for tab grain films. To keep the grain from going mushy in the second bath I use much less sulphite than that - about 5 to 10 g/litre. For alkali I use about 5 to 6 g/litre sodium metaborate (kodalk). The first bath is used one-shot, the second is re-used. Despite these, and other, dallyings, and DiXactol Wonderbrew, I still like APX400 in Rodinal and have this little voice that always says: 'just stick to APX400 in Rodinal and keep going'.
