Diafine, though, never used that before, though perhaps I'll pick some up in the city tomorrow. It's a little out of my budget, though, doesn't acufine do the same thing?
The thing to keep in mind with Diafine is that, as a 2-bath developer, you can keep reusing the working solutions as long as there's enough to cover the film and still get the same results. Better, you can replenish it by making up the lost volume in Bath A with fresh solution, and pouring off enough Bath B to add the same amount, and it will literally last decades. Because of this longevity, you can't look at the price quite the same way as you might with developers that get used up.
And yes, Diafine does some of the same things Acufine does -- it gives a significant EI increase and a real speed increase with most films, but because it's two baths and the same time for a broad range of temperatures and all films, you can do stuff like mix Tri-X, Plus-X, and Delta 3200 in the same tank, as well as develop without a thermometer or even a fancy timer -- just look at you watch, since a little extra time won't hurt anything. And when it's 85F out, and you don't have any water in the fridge, Diafine is the best thing you can possibly use; it'll give practically the same development as it would at 65F.
However -- if you shoot Tri-X at EI 400 and develop in Diafine, though still printable (with patience -- exposures will run long), the negatives will be so dense as to be impossible to scan (speaking from experience on a scanner that holds to a rather strong Dmax). Some folks consider the EI 1600 recommended by Diafine's maker as a little high, but EI 1000 is a very good compromise -- and *way* out of the Holga's range in daylight, unless it's deeply cloudy and looks like about to open up a downpour. Plus-X at EI 400 (for Diafine) would be a much better choice, even outdoors, in NYC (IMO).
BTW, don't forget to take along or buy a roll of black tape for the back of the Holga -- without it, the light leaks might make your first rolls more experimental than you want...
