Hey Cal, your comment about the non HP finder inspires me, to get and try one of those with my F3HP and Noct.
I didn't shoot the Noct at all the last months, as I have preferred the Leica M bodies and rangefinder focussing, but man, I do miss that Noct!
I am now shooting also a lot more with external meter in the nights, so the mediocre LCD in the F3 might not pose much difficulties, just using it as a meter less body.
My standard film actually is TriX400 @ 3200 in D-76 1:1 - I would be quite interested in your results of push experiments.
I just lost my favorite lab (price raise by 40% !!!), where I had my film pushed in D-76 and finding another with consistent quality @ 3200 seems impossible !@#$%
Looks, like I have to start developing myself again (preferring Kodak TMax dev, to push TriX to 3200).
I just bought a chrome F2 with DE-1 eye level prism to go meterless. I was lucky and only got it for $299.00 at B&H. I'll use my Gossen Luna-Pro as my external meter.
I rigged both my F3's with MD-4's so I could short the illuminator light switch so that whenever the meter is activated the light comes on. The only problem with this mod is that it requires use of the MD-4 for power because battery drain is an issue.
The F2's DE-1 eye-level prism is very much like the DE-2 on my F3 non HP. Less magnification equals a brighter viewfinder with more contrast than a DE-3 HP finder. I find the DE-3 HP finder is best suited for use with long lenses and that is why I have the 105/1.8 AIS permanently mounted.
Anyways long developement times lowers contrast. RanceEric posted and shared with me his development for HP5 at 3200 ISO using Microphen. He gets nice greytones that are acually amazing considering the film speed. His trick is to minimize aggitation where he only performs two gentile inversions per minute, but this requires an extended developement of 25 minutes. Also Rance's images don't have the blown highlights that often come with extreame high ISO. Like in stand developement highlight development is limited.
I also saw a pattern on the Massive Development chart where Tri-X and HP5 use all the same times, but the ISO's are staggered. Tri-X at 800 has the same time as HP5 at 1600; and Tri-X at 1600 has the same time as HP5 at 3200 ISO. I'm hoping that I will be able to shoot Tri-X at 1600 and HP5 at 3200 using RanceEric's process and be able to process HP5 and Tri-X shot at different film speeds all in the same tank.
This would be great because I shoot lots of film and have the capacity to develope 8 reels of 135 at a time. Also even better if I can cross formats and process 135 and 120 in the same tank.
I guess I'm spoiled because I have gotten Diafine to work for me. I'm basically just a clever slacker who wants to get the highest output, yet the highest quality, with minimal effort. Also at the lowest cost.
I will start with a 4 reel batch first restricted to 135.

P.S. Also want to try Acufine, another high energy developer. I use to use a lot of ID-11 at 1:1. I liked it for lowering contrast, but it does not have the pushing abilities of Microphen, especially at the higher ISO's.
