Would potassium metabisulfite be less likely to be oxidized to a sulfate than potassium sulfite? Some extra KOH would be needed, but the combination might be less expensive to the hobbyist who makes relatively small batches. Or, can one of you tell me a source of relatively small amounts of the liquid concentrate?
I have what I believe to be an excellent Metol analog of Rodinal, but have only been able to test the sodium sulfite version. Even so, it seems to be capable of greater SBR and better shadow detail than any of the many Rodinal expedients I have tried.
The attachments are from scans of a 10X print of a 35 mm EDU 400 Ultra neg. That puts the detail at about 30X, enough for a 30"x45" print from the full width of the negative. The viewing distance for such a print for proper perspective would be about 54" (no grain sniffing allowed).
