BTW DF, glad to see you're visiting APUG again.

Thanks, Jim... Glad to be back to the stinky old darkroom !

Dr. Lowe formulated Edwal 10 as a mid '30s variation on D-76,
suggesting that he approached E-12 as a D-76 variation as well.

Edwal 10

Water 900ml
Metol 5 grams
Sulphite 100 grams
Glycin 5 grams
Borax 10 grams
Water to make 1 liter

Since many of us, myself included, use D-76 to maximize shadow detail while holding the highlights, Edwal 10 might be a good N+1 developer.

The grain structure is very much like D-76 if you use a dilution of 1+5 ~ 1+7. Where D-76 might let brights run to gray, E10 will keep them perking along, like Rodinal.

The biggest difference between 10 and 12 ? Finer grain with 12. If you don't want to mess with PPD, and know D76 pretty well, E10 is worth a try.
