I'm going to a funeral this Friday and thought I'd try to make a few semi-formal portraits of friends and family. I suspect that most of the opportunities will be indoors and, out of respect, I am opting for no flash. I've got a fridge full of Tri-x and a couple of un-opened cans of Acufine...so, thought I'd give that combination a go. Here's the thing. I've never used Acufine before and I don't think I'll get much chance to do any testing before departure so, I'm looking for reassurance that this is a good choice and perhaps some advice with respect to dev times & c. The label on the can says I can rate Tri-X 400 at EI-1000 and dev for 5 minutes at 70 degrees F. Does that sound reasonable?
