Oldlugger Posted November 10, 2009 Share #1 Posted November 10, 2009 Advertisement (gone after registration) Can anyone suggest a suitable 39mm filter to create good infrared effects in black and white range finder photography? The Hoya R72 is probably the best for larger lens sizes but I can't find anything similar for smaller RF lenses. I will be using a Leica M4-P and the Voigtländer 35mm f2.5 Colour Skopar lens, and Ilford SFX 200 film, or one of the true IR films currently available. I've done a lot of B+W infrared in the past with very good results, but this was using a Nikon F4s and Nikkor lenses, plus the now obsolete Kodak HIE film. I used a No.25 and polarising filters at this time, both producing excellent results. Any suggestions (and where to purchase - preferably in Europe because of import taxes) would be much appreciated!

richam Posted November 10, 2009 Share #2 Posted November 10, 2009 I have the B+W 39mm 092 (deep red) and 093 (opaque) filters, and use them for infrared. With SFX 200 and some other films, the 092 will work. Naturally, the IR effect is greater with the 093, but the 093 has a cutoff that makes most IR films difficult to use without a tripod and very long exposures. I have used the 093 successfully with Kodak HIE and with some IR sensitive digital cameras. I got mine in the US, but they should be available from many dealers in Europe. Here's the B+W site with technical info: B+W 39mm Screw-In for Infrared - Schneider Optics Link to post Share on other sites More sharing options...
stunsworth Posted November 10, 2009 Share #3 Posted November 10, 2009 I've also used a 093 filter with success - however I've used it on an M8 rather than with film, so I can't comment on the film side of what you are doing or what exposure to use etc. If you think an example would be relevant let me know and I'll post a couple.

Oldlugger Posted November 10, 2009 Author Share #4 Posted November 10, 2009 Many thanks for your replies richam and stunsworth (good user name this!). Most helpful. If you were able to post an example photo or two stunsworth, that would be very interesting - to see what a digital camera can achieve in IR (without post processing I take it?).

stunsworth Posted November 10, 2009 Share #5 Posted November 10, 2009 Simon, here are a couple of examples. IR shots on the M8 have a purple colour, but other than desaturating the image the only other post processing is applying a curves adjustment. Welcome, dear visitor!

tgray Posted November 10, 2009 Share #6 Posted November 10, 2009 I'd either use the R72 and a step up ring or a B+W 092. The R72 has a cutoff wavelength (I think 50% transmission?) of 720nm, while the 092 has it at 695nm. Pretty close. The 092 will let in a bit more red, which isn't a big deal with films like HIE, but you won't get as strong as an effect with SFX200 as you would with the R72. However, you might like the results more. B+W has the specs for RG715 glass in there spec pdf, but I don't think they make a filter with that glass in it. That would be very close to an R72. I think an 093 will be too extreme for SFX200 since the cutoff is at 830nm. It might just be ok with some of the other IR films like Efke, but I'm not sure. So, if you have a bigger R72 filter lying around, pick up a step up ring for $10. Otherwise, just buy the 092 and be happy. This should give you similar results to what you got with HIE and a 25, though it will be slower. Link to post Share on other sites More sharing options...
Oldlugger Posted November 12, 2009 Author Share #7 Posted November 12, 2009 Advertisement (gone after registration) Great pictures stunsworth! I particularly liked the last one. Any more? Cheers for your info tgray - very helpful. Simon Link to post Share on other sites More sharing options...
richam Posted November 12, 2009 Share #8 Posted November 12, 2009 One caution about using IR filters. There are some lenses that produce hot spots at small apertures. I posted an example here: Hot Spots You can also play around with color IR. Not really my bag, but tried it by swapping the red and blue channels in PS instead of grayscale conversion: Color IR Link to post Share on other sites More sharing options...
stunsworth Posted November 12, 2009 Share #9 Posted November 12, 2009 Great pictures stunsworth! I particularly liked the last one. Any more? Here are a couple more taken this summer. All the IR photographs I've shown were taken using a Voigtlander 25mm lens. Welcome, dear visitor!
