So far my holidays allowing a test with the new Foma film: Retropan 320 Soft:

OK, let us try something with that Rollei Supergrain 1+9 developer on E.I. 640.

HC110 dilution ??? B is certainly most common, but they do not specify which dilution they used.

No problem to test the film in HC-110 either.
The time is indeed for HC-110 dilution B (1+31), a small mistake from the flyer delivered with the film.

A first test strip is hanging to dry. I am already sure that I have to adapt the Supergrain 1+9 developing time a bit longer then the recommended 11 minutes (20C) on the flyer of the film.
I will make a Split Grade test print maybe tomorrow.

Testing is much appreciated.
I have seen a number of results which have not impressed me but I have no great faith in the testers. Grain and blown highlights have featured but who knows how well they are scanned?

Just interpolated some data for E.I. 640 and E.I. 320. The given data for Supergrain 1+9 is way off so I have to start the measurements from blanc data.
Here a first result, Zorki-6 and I-50 with Retropan 320 E.I. 320 in Supergrain 1+9, 8:00 minutes (20,0C) and still for zone V 0,54 logD only (should be 0,72 logD). Hence consequences for especially the high lights. Split Grade print on gradation 4,3. (Around 2,5 would be correct).
First impression:
1. This is a real grainy film, even a bit more then Foma Fomapan 400 film.
2. The film is drying absolute flat.
3. Effective film speed around iso 320-400, a push development is possible but not much higher then iso 640-800.
4. There are no markers or index on the film strip. It is completely blanc. This is from a bulk 30,5m/100ft film.
5. This emulsion looks like the in 2001 discontinued Fomapan T800 film. I have to dig up that data from 1997-2001 but at that time I had no densitometer.
Mr. "Stip" which means "Dot" in Dutch language. He is really grainy ....

Next developer: HC-110 dilution B (1+31). Retropan exposed on E.I. 320 again.
A new test strip is hanging to dry. I took 8:30 minutes (20C) because I am printing in Split Grade with a combination of a diffusion box and a condensor enlarging system (Dunco II 67 120 Pro). In optimum preformance the highlights are around 1,25 logD with the densitometer.
Control strip on zone V. Should be around 0,72 logD.
Just for a practical impression of the wet strip: Pretty good now.
Another interesting thing is the very fast Clear time of this film. In a regular Acid type fixer (RXA) 1+4 less then 30 seconds. So the minimum recommended fix time of 3 minutes is possible without any problem.

Well I just measured the negatives:
Highlights: 1,05 logD; the Grey card (zone V) 0,62 logD (should be 0,72 logD) so for my enlarger I still can go up for the developing time.
For a quick working type developer HC-110 in 1+31 you can see now this is a really low contrast type film.
Suitable for a good scan now, less suitable for my Dunco II 67 enlarger system.
Pictures will follow later ....

A test of 4x5" Foma Retropan Soft here:
https://www.flickr.com/photos/jshillaw/20202203638/
Looks very promising. I wonder when the stocks of 9x12cm will appear?

Split Grade print from Retropan 320 Soft E.I. 320 in HC-110 (B) for 8:30 minutes (20C). Zorki-6 with I-50 (F/3,5-50mm). Well insiders know how I get all these nice F.S.U. RF cameras.
In HC-110 it is really a grainy film, from the 50's. Retro style. Well my wife, from Ukraine is also from the 50's .......
Another example in HC-110 (B):

OK, next film, E.I. 640 in a speed enhancing type developer. Let us look what this Retropan 320 Soft can do in a push +1 development.

Retropan 320 Soft E.I. 640 in Diafine 2-bath. You can only "hope" for a speed enhancing effect of 2/3F stop with this combo. Summer in Holland is also a bit warmer now: 25,5C film development. In fact not a problem for Diafine which should be in the range of 21-28C.
Unfortunately not a good combination. There is hardly any speed increase, so the end result is an underexposed negative and loosing 3 zones in the highlights.
Measurement in the test chart and densitometer are only confirming this. NOT recommended!
A pity for my last original Diafine BKA 2x950ml/1 Quart.
I have to try something else for more speed for this Retropan 320 soft Foma film.

Developed in Microphen 1+0 during 12:00 minutes (20C). The maximum density in the negative 1,05 logD and easy to print. E.I. 640 and still a lower type contrast and now you have really grain.
Kiev-4AM + Jupiter-8M, Gossen Lunasix-3 exposure.

A few shots with the test chart, from F/2,0 and F/4,0 with my Leica M7 + Summicron 50mm. Retropan 320 E.I. 320 in HC-110 (B) 1+31 (9:00 minutes at 20C).
F/2,0
F/4,0
Printed in Split Grade, grade 4. This film is looking like the old Tri-X 400 but then with a lower contrast. Zone V (Grey chart) = 0,62 logD.

I got this info from Foma in regards on how to process sheets in w27 (XTOL) 1+1:
[FONT="]Let us recommend you to use the developing time of 7 minutes (El 320), eventually 9:20 minutes (El 640) corresponding to the temperature of 24 °C.[/FONT]
Didn't try it out yet, but will probably next week, when I have some exposed sheets.

I will be interested to see these. I am preparing to buy 300 sheets in 9x12cm for my uses.
