Thanks for the detail. I said that idea is surprising because if one believes that ascorbates are pretty inactive in low pH environment then we would not expect the behavior of D-23 to change by adding s.a. But John Hicks reported faster process and finer grain... I'm more curious about the general potential of D-23 with s.a. than particular application to d3200, so maybe I'll try it with HP5+ or something.(posted 8327 days ago)Pat Gainer also suggested to replace hydroquinone in D-76 with s.a. It's more like a vitamin enriched D-76H (let's name it something like D-76HC) or D-23C with borax. It may be interesting to change the base while the reductants (2g metol + 4g s.a. in 1 liter) are held fixed and see what happens. Well, too many things to think about for now.
