Ready to shoot Rollei Infrared in 120, a few questions

[brian steinberger]

I just bought a roll of 120 Rollei Infrared 400 for fun. I've always wanted to try infared. A few questions before starting.

1. I'm sure the true ISO is not 400, but I've read that it could be as low as 32? What's a good starting point to rate this film?

2. I have a #29 red filter. Are you supposed to use it for every shot? What about filter factor? Still 3 stops?

3. Can I meter using the zone system, just as I would with traditional B&W?

4. Any starting development times using ID-11 (D-76) or Pyrocat HD?

Any other advice also welcome! Thanks!

I just read something about filters for infrared. Doesn't look like my #29 is going to cut it. B&W also has an 89B which is one of the filters that Rollei recommends with their film. And the fact that this filter is accounts for 5 or 6 stops brings the effective ISO down to around 12. I'm starting to answer my own questions.

I'd like to see other thoughts on filters. Thanks

This is the advice I got on another thread regarding this film...
"Rollei IR 820/400 is suitable for use with a SFX filter, 695nm, 715nm, Hoya 72 (720nm) or Cokin IR filter (720nm). With a red filter you will have no wood effect."

Before I was told this, I used a #25 filter and I didn't like the results. I have yet to try one of these filters but keithwms has some nice examples of it in his gallery.

Hello Brian!

Your #29 red filter will not work. You should use an #89B or #88A black filter, and set the light meter to ISO 25 (!). Don't measure the light through the filter. For more detailed information send an E-mail to: photo@mahn.net , there you will get more detailed information, how to use this IR film properly.

Cheers

I use a 695 filter, set the meter of my Bessa-L to 320, and meter through the filter. Works just great. Of course, a different meter might give different results.

Wow, find my own words back

Here some Rollei IR-820/400 examples. Filters used: SFX, Heliopan RG715nm.
I will upload some examples of my Horizon 202 panorama camera. Equipped with a self cut and made Cokin 007 (720nm) polymer I.R. filter

Next try will be the new Maco IR820C film. It's an extended APX100 820nm - 850nm based I.R. film. But iso 100 only which will be effective E.I. 3-6 with a filter. This film will probably work with a dark red filter to get some 'wood' effect.

The Rollei I.R.-820/400 will end somewhere between iso 12-25 with the Heliopan RG715nm filter. Pretty easy infra red film in handling.

Best regards,

Robert

I recently shot a few rolls of the Rollei 820 with an 89B filter, but I used ISO 3 and 6 (3's better). I souped it in Xtol 1:1 for 12.5 minutes. good negs.

rollei infrared

Just purchased 10 rolls of Rollei infrared and a Hoya 720 nm filter to experiment with . Looking for the best iso setting to begin with . Have read several photographers postings on the web , info is all over the place . Is there anyone that has tried several things and found the best combo ? I shoot most my film in hot tropical light . Robin

There are too many variables IMO to recommend an ISO with any certainty. I suggest you use your first film as a test to establish the best rating for you.

The most frustrating thing for me is the various manufacturer's filter numbers and names. too bad there wasn't some sort of standard method of labeling. Well, there probably is, but it isn't apparent.

There are a couple of Rollei IR films on the market. The old IR 820 was made by Efke, and it's still made under that brand. (Efke).
The new Rollei infrared emulsion is....rather optimistically marketed. It's very good film, just not very good for IR. You'll need a very deep red filter like the Hoya R72 to get a quasi infrared effect. I tested it extensively this summer. I was able to get some decent foliage effects when exposed at ISO 25 via handheld meter. But I cannot tell if it was because of the wood effect or overexposed highlights. Forget the zone system when shooting infrared, unless you mean the twilight zone system!
You can see some examples here:

Hello,

I have tried this film with a B+W 092 (ISO 12-25), Heliopan 715 (ISO 6-12) and Hoya R72 (ISO 3-6). The Hoya R72 provides the stronger IR effect, with the B+W 092 the IR effect is barelly visible, and the Heliopan stays somewhere in the middle.

As for developers, I've used Xtol and the Recomended Rollei High Speed developer with similar results.

Regards,
