I did a 120 roll of tmax 100 in rodinal 1:50 for 12 min. at 20c last night and the results were noticeably thin. I don't have a densitomiter (unless there is a way of measuring it using a film scanner?) I plan on trying some prints this afternoon but the negatives were well exposed, in fact I usually meter for 64 iso on this film. I've developed it before in tmax developer and they always came out much denser. Is this a normal thing for this film/dev, should I try 1:25 next time, or simply extend the developer time? What times are you folks using in this combination? I mix using appropriate graduated cylinders and the concentrate is stored in a tightly sealed dark glass bottle.
