Nice job. Have you tried the faster films? I have not myself, just wondering if you did and compared them side by side.
Ilford P3200 is still available, according to their website, and it would probably be the best choice at EI 1600 or 3200. Unfortunately, Kodak TMax P3200 has been discontinued, although there may still be some frozen stocks left...
Ilford Delta 3200, T-Max 3200 (both ISO 1000, per their respective manufacturer's data sheets), and Neopan 1600 are your only "true" b/w options in that range. Neopan 1600's ISO film speed is not published in it data sheet, but it is probably similar to Kodak's and Ilford's, and definitely not 1600. Most I have heard on the Internet claim it is 640, give or take. However, most people who do individualized speed testing on the Internet don't do it using the same ISO standards as the film manufacturers, so that is only really a useful number when performing tonal placement (e.g. with a spot meter).
These are the films that will have "normal" or "near-normal" exposure and contrast when shot from EIs 800 to 1600, assuming that the composition itself contains a "normal" brightness range. Any of the 400 or slower films will have higher-than normal contrast if shot in that same brightness range, if you shoot them at 800 to 1600 and push development. Pushing helps improve the poor results you'd get without pushing, due to the underexposure that occurs when you rate it this way.
The only b/w films that will truly give you correct or near-correct exposures at 800 - 1600 (i.e. without underexposure) are the three I mentioned. This does not mean that films slower than these don't make for great results when uprated and pushed, however.
I have Tom. The are basically the same.
P3200 is NOT discontinued. In March/April of this year, it was out of stock everywhere. I called Kodak and they said they were out of it, and it was scheduled to be recoated at the end of April or early May (I forget which). Sure enough, around mid-May, it reappeared on the shelves.
One could estimate the real speed of Neopan 1600 by looking at the characteristic curve. In D76 it looks like somewhere in the neighborhood of ISO 500 to me. This is somewhat complicated by the fact that I don't think Fuji actually shows the characteristic curve for any of their recommended dev times for EI 1600. To be honest, other than a more pronounced shoulder, the curves are barely different from the Neopan 400 ones.
Where did you learn of TMZ's discontinuance? It's still listed on Kodak's web site. I've seen no notice of it's discontinuance, and I've seen it on the shelves at B&H and Adorama. Ilford's Delta 3200 is available in 35 mm and 120 formats, wile Kodak's TMZ is available only in 35 mm stocks.
