Yep. 3dB down at 720nm. Lets in just a touch more red than the average
"I" filter. Not really visible, but helps the autofocus. A couple of
years ago, this outfit <www.2filter.com> sold me a R72 (Hoya), a.k.a.
89B (Wratten) filter mounted in a 58mm ring for the low, low price of
$38. They've gone up some since.
The weird colors are a result of the different sensitivity of red,
green, and blue *sensors* being bathed in this unusual light starting
from deep red on back to wherever the response fizzles out. That and the
auto white balance in the camera desperately trying to make sense of it
all. Sometimes I just take whatever channel of R, G, B is least noisiest
and print a monochrome image but people say the color versions are trippier.
Now, a local thrashing post-pre-i'm-not-really-sure-punk band wants a
set of band pictures taken with this gear. I'm scouting locations. An
ex-drummer-ex who was in the 1980s-90s ATL-Athens scene emailed me and
said she was a recovering victim of bad band photography. She urged me
not to pose them near delapidated barns with kudzu growing all over them
or other Southern and R.E.M-ish cliches.
But shambling kudzu monsters look really k3wl in IR, like being covered
in albino pythons. This band night actually *like* that.
