"I'd recommend using a stop bath with this developer, since it tends to carry on working quite strongly in a plain water rinse. Maybe this isn't quite so noticeable at 1+14 dilution." (Pete Andrews)(posted 8180 days ago)What about stopping the development half a minute or maybe a minute earlier?
I tend to avoid acid stop bath unless I fear undesirable staining (unlikely with Ilfosol-S). Ilfosol-S uses carbonate, another reason I shy away from acid stop.
