Anyone try D-76 at 1+2?

[Horatio]

Seems the recommended ratios for D-76 are stock, 1:1 and 1:3, the latter for higher acutance. Is there no value at a 1:2 ratio? Seems the potential acutance would be greater than stock or 1:1, with less grain.

Just curious.

I have, it's fine, it's slightly sharper than stock, or 1+1, but also slightly coarser grained. Not hugely different from 1+1 though. Saves a bit on developer and gets a bit cheaper.

I’ve used this dilution exactly once, when I didn’t have enough developer left to get 1:1. I was developing a single roll of FP4+ and, as I recall, the results were as Anon Ymous describes: not significantly different than 1:1.

I use ID-11 1+2 occasionally and I haven't scrutinised the negs hard enough to tell the difference between it and 1+1 or 1+3. Nothing jumps out, change-wise, anyway. I kid myself I'm saving a bit of time over 1+3 but it's academic, really. It's only typically 5 minutes!

I mentioned it in an e-mail to Ilford technical department and was told that the only reaon it wasn't mentioned was that there wasn't room to publish every dilution and yes - quite a valid option and this is borne out.

Thanks for the responses. Looking at the data sheet linked in another thread, am I correct that a gallon of D-76 is good for only four rolls of film, unless replenished? Seems one poster here indicated he got 10 rolls by extending development time.

EDIT: Nevermind. I see now it's four rolls per quart, or 16 per gallon.

1+2 works well, the sharpest 35mm negatives I've processed for anyone were take with an Exacta Varex 1000 and CZJ lenses, FP4, and ID-11 at the photographers reques at 1+2, actually replenished D76/ID-11 gives very similar results.
