This may have been discussed before, but I have bought some 400 Rollei I/R b/w film to try. My last experience years ago was with some Kodak product. What do you suggest I rate the film for exposure given that I will be using an I/R filter (an IR 76). Any advice will be appreciated.

I've been using this film with an Heliopan RG 715 filter. With this filter (light under 715 nanometer will be blocked) I get excellent results.
Very good Wood effect with clear white leaves.

For IR exposure series are recommended, because the IR intensity varies during the day.

The best Wood effect you get if you have an angle of 90° from your shooting axis to the sun.
In that case and with the 715 filter I expose the Rollei IR (you can also use the much cheaper Retro 400S and Superpan 200 and get absolutely identical results) at ISO 5 - 6.

These films can also be developed as slide films in the Agfa Scala process with outstanding results (some labs in Europe offer that service, I can recommend Photostudio 13).
BW IR as slide on a lighttable or projected on a screen is breathtaking and looks much much more impressive and brillant than IR as a normal print.
The Wood effect really shines in a BW slide.

Cheers, Jan

P.S. Just forgotten: As you are located in downunder, afaik the "lighthouse lab" in Australia offers the Scala process, too

Yes, a 715nm filter works the best (#88A). Depending on the IR circumstances in the atmosphere iso 6-12.

I have tried the Retro 400S under the same conditions and you can get simmilar results.

Best regards,

I've used a Hoya R72 and bracketed from 6-25 for landscapes. Comes out great. Results do very by the conditions of the atmosphere. It's winter up north now. I have a ton of the stuff in the freezer. This spring I will try and create an exposure index against my M8 using this film. This way I can avoid all the bracketing and make better use of the film.
 
Has anyone tried the Rollei IR 400 film with a 003 red filter?I'm dying to try this film,but don't want to waste it if this doesn't work at all!Any experience with this would be appreciated.
Thanks,Peter

I suppose you mean a Cokin 003 Red filter?

With a Red filter you won't see any wood effect. For the Rollei IR-400(S) you need at least a 89B (695nm) or better the 88A (715nm) filter. Hoya 72R (720nm) is also ok.
 
Save your film for the summer, when there is more IR light, and when the foliage is full and green. I like to shoot IR400 at ISO 12, shooting between noon and 2pm. I use a Hoya R72 filter.

I just bought some IR400 in 120 format to shoot in my Rolleiflex, I hope to get some good shots in Kyoto this summer.
 
Thanks everyone for your replies,now I'm off to find one of the proper filters.
Regards,Peter
