Rating it a 1600. Ten years ago it also worked for me at that ASA with my Nikons in Rodinal. (At 16 minutes at 70 degrees agitating once per minute.) Nowadays i run my Leica m's in Xtol! :) As this is the same time as my Delta 400 I throw them both in the same tank. Blown highlights=overexposure and/or development thin shadows=underexposure, indicates you should expose more, lower you asa/iso number. So you have conflicting problems. One should cancel out the other. But they don't. I'd shoot 4 rolls, run it in a one quart tank and contact it and look at it. Mark Rabiner
