[Leica] IR photography with M8 and Elamarit-M 24/2.8

[Howard Ritter]

Thanks for the tutorial! I’ll post some results if it’s not too late in the season. Even here in my new home in NC, most of the trees are in pretty sad shape!

The B+W 093 appears to result in good images from what I’ve seen online, but its specifications seem to indicate that it admits only wavelengths longer than where the M8’s filter starts to be really effective. OTOH, the 092 filter appears to pass a good deal of visible red, not what I’m after.

For some reason, the answer to this seemingly simple question has been astoundingly difficult to find by googling.
