Well, not very happy with the results on paper. Wet printed from the D96 negs, stuff shot at ISO 80 and 50, run with reduced agitation in an attempt to minimize highlights blocking up and hold shadow detail. Still needed to print on grade 1 or 0, and not terribly good tonality. I suppose this is just not a film I'm going to bother with.
My goodness, use to shooting sheet film, but happily dug out the old 35, last week and shot some B&W, and developed it to be sure all was well with the camera.
So loaded it up yesterday with p30. Sure not use to shooting so many shots in a day. My of my, .ah ha... 18 yesterday and 18 shots today. Phew...Lot of,work.
Now for the question:
We usually do a quick inversion for B&W with some agitation for 5sec, so want to verify the agitation process for this film.
We have two developers available. D-76 and Hc-110. Do not have any D-96, but on Film Ferrania, (Dead Link Removed) there is a note, (formula to make your own D-96 here) But, alas that's a "Page Not Found"
So tomorrow going to try the first development in HC-110, and it states:
"Small tank, continuous inversions first minute, 10 second inversion each minute - or - Jobo, rotation"
Reading we have found that most feel that agitation with P30 should be gentle, believe we read somewhere here, if we remember correctly, that one person suggested that they would slowly and gently, with one hand do an inversion, set down the tank, and then with the other hand, gently do another inversion.
So for a ten second inversion each minute, how does this sound? Or perhaps some other suggestions?
Excited to see how it looks in our bright southwest, and most likely the adjustments will have to make in shooting and developing.
Thanks fer yer help...
Don’t mean to disregard your tests, but I exposed one roll as EI 50 and developed for the recommended time in D-96 stock/tank with continuous agitation — slow inversions, maybe a little faster than yours — and got blocked highlights. I still didn’t try to print or scan these negatives, so I still can’t say anything about the shadows and midtones.
How has everyone been finding the edge numbers exposure?
You did notice that I used the D-96 at 1:1 dilution? And, developed for only 6 mins, not the recommended 8 mins?
The actual film speed--at least, with my camera and external meter--is EI40 (this speed obtained developing for 8 mins in D-96 @ 68F with continuous agitation.)
How has everyone been finding the edge numbers exposure? They seem pretty thin to me.
@fdonadio, I determined film speed through my normal testing procedure of exposing a black card, in open shade, to various EI settings, and then measuring with a densitometer to find .10 above fb+f. Following the Best Practices document produced way over-developed negs for me. YMMV, of course.

A black card has no definite brightness level. I bet it can range over 5+ stops, depending on the nature of the "black", e.g. lustre with some specular reflection thrown in or a high-perf engineered black (https://en.wikipedia.org/wiki/Super_black), or even better a physicist's "blackbody": a small hole into a black felt-lined box.@fdonadio, I determined film speed through my normal testing procedure of exposing a black card, in open shade, to various EI settings, and then measuring with a densitometer to find .10 above fb+f.

It actually says ASA 80, and somewhere Dave Bias stated that they did not repeat (yet?) speed testing but accepted the legacy value. Curves and some more science would be appreciated, but again Dave stated it is not a priority so it will not be done (a shame, imho).-) This film has got the ISO 80 designation on its box.

Zone 0 is a properly metered gray, under-exposed by 5 stops.
