Rollei R3 at 6400 or ??

[Michael W]

Has anyone tried the Rollei R3 at 6400? I'm interested in 120.

Alternatively ... I'm looking for a film to use in my Pentax 67 for shooting night interiors. I've been doing OK in 35mm with Neopan 1600 developed in Diafine. Exposures are f/4 at 1/30 down to f/2 at 1/15 in some places that just have a couple of fluoro tubes.

If Neopan 1600 was available in medium format I would be all over it. Because it isn't I'm considering the following. Useability in Diafine would be a bonus.

Rollei R3 at 1600, 3200, 6400
Is it good at these speeds or does it look very underexposed. Anyone tried it in Diafine?

Neopan 400 pushed to ...

Delta 3200 at 1600 in 120

Tr-X 400 at 1600 in Diafine

I'm not expecting people to solve my problem for me. I will most likely buy all these films & try them out. Just interested to hear from anyone who has already been down this path. The Neopan 1600 gives me good shadow detail.

R3 is a 3-layer film with emulsions from iso 50-150 and 500. Iso 1600 is almost a push +2F for this film.
Diafine is not succesfull with R3. You have to try a depth developer.

I don't have experience with the R3, but I did play with some films in low light at fast speeds last year. So, I can say, that from my [limited] experience ...

Neopan 400 pushes, but not well. I've gotten it to EI 3200-ish, but the shadows are completely gone much past 1000 or so if you're shooting dark scenes.

Delta 3200 is great [IMO, best] at 1600. I think that 3200 is a little high for this film if you want to retain shadow detail. I've had acceptable to good results with D-76 and great results in Microphen. It's grainy, which can be an issue in 35mm, but since you're shooting 120, you'll be fine.

Tri-X 400 is, IMO, great for pushing. I've had it as far as EI 6400 (in TMax RS) with surprising results. It works well in almost all situations at 1600. I would use something other than Diafine for it, though. D-76 (or ID-11) works very well for Tri-X at 1600, and is easy and inexpensive to obtain.

I'd reccomend the Delta 3200 @ EI 1600 or Tri-X at EI 1600. I wouldn't bother with the Neopan 400.

First, excuse me for my english, i hope than you understand my answer.

I shot one 120 at 6400 iso. I developed with Rolley RHS with one minute of pre-wash before the developer. The end result is not bad, but is obvios than the limit of this film is exceed. I invite you to try and see the results, perhaps it likes you.

The best range of this film is between 50 and 200 iso. 400 i don´t like very much, but 800 is better for me than rolley retro 400 shot at 800iso.
The developed advised are rolley rhs and rls it depend the iso to use. But there is a great art-developed called Isopleno of Gago Products. The times are smaller and the results better, and you don´t need two developers and don´t need pre-wash.

I hope help you in spite of the fact my english is very bad, best regards,

Ruben

Going a bit more in detail for this special 3-layer film:

Depth developers suitable for Rollei R3:

R.H.S./AM74 (Amaloco) 1+7 or 1+9
R.L.S./CG512 (Udo Raffay) 1+4 (on 24 degrees C !)
Rodinal 1+20 or 1+25
Xtol stock

best preformance of this film: iso 50-200 with R.L.S./CG512
nice preformance: iso 200-iso1600 with R.H.S./AM74
nice overall preformance: for Rodinal and Xtol iso 200-400.

R3 is comparible with Tri-X (400) in the middle and high iso range. Tri-X will preforme better on iso 1600. R3 is better in the low iso range (50-200).
The pre-soak for this film is important and should be at least 1 minute, preferable a bit longer.

R3 is made on clear PET layer with an excellent non-curling layer. 35mm cartridges you have to load in subdue light due to the 'light piping' effect of this clear layer film. R3 is also very suitable for scanning and reverse processing. The film has an extended red sensitivity just over 700nm.

ROLLEI R3

Has anyone tried the Rollei R3 at 6400? I'm interested in 120.

I'm not expecting people to solve my problem for me. I will most likely buy all these films & try them out. Just interested to hear from anyone who has already been down this path. The Neopan 1600 gives me good shadow detail.

The ROLLEI R3 was introduced for the first time in 2004. Since then it is very popular in many countries. Particularly, as sheet film, which is available in all possible film formats (Freestyle).

However,....the processing of this film is not completely unproblematic.
I recommend to download the R3 data sheet from the rolleifilm.de webpage.

Very important is: The film must be pre-soaked to reach the max. sensitivity. I the range between 25 and 200 ISO, developers like ILFORD Perceptol or ROLLEI RLS are compelling recommended. In the ISO range around 200/400 ISO, practically each normal developer is applicable. Starting from 800 ISO the processing becomes fastidious. It actually concerns thereby not only the developer, but also the special processing.

As I have heard from ROLLEI-FILM, that a new developer "Made in USA" is in the pipeline in January 2008, perfectly co-ordinated for the use of the ROLLEI R3 with higher ISO values.
