I recently acquired some glass plates, and the developing instructions with them are a bit scarce. They advise 5 min in HC-110 dil. B "or equivalent." I used straight D76 for 5 1/2 minutes. Looking at some of my favorite emulsions, the times seems comparable. I think I exposed the plate fairly well(metered, but 4s at f/22 under an overcast sky and EI 2), but it's still quite thin. So, with that in mind, I'm wondering if anyone can advise any guidelines on how to get things at least in the ballpark for developing these. Alternatively, I'm guessing that I should just buckle down and buy some HC-110. I'd have picked some up if the local camera store carried it... Also, for reference, I also have Rodinal, TMAX, and Dektol on hand. I'd appreciate any advice if any of those would be more suitable.
