> Do you have any more info on the vit-C used with Rodinal at 1:50/75 or 100 for us?(posted 8242 days ago)I ran a couple of sheets of TMX and Acros in Rodinal 1:100 with sodium ascorbate added at the rate of 4g per liter working solution.
Frankly I couldn't see any significant difference at 8x or 30x between that and Rodinal 1:100 w/o ascorbate. It _may_ have been slightly finer-grained but otoh that could've simply been wishful seeing.
The only difference of note is that both films were 1/3 stop slower for CIs matching the non-ascorbate Rodinal. Actually I used the same development times; the curves were the same but simply displaced.
A side note; recently I've been fiddling with Delta 3200 in D-23 1:3 for EI 1600. The addition of 4/gL sodium ascorbate gives the same EI and CI with 25% less development time and the graininess is easily visibly finer.
