Someone asked about "ND" filtration for IR-shooting. Yes, normal NDs look more like clear glass.
So, I made a test with the Tiffen Indie set (IRND). I was a while ago a little sad to have spend money at all on them, greenish tint and not really cutting IR. Which brought up the idea, to do a test as they don't work as a real IR cut filter: mix it with a IR pass filter.
(BTW, using the Motion Mount shows, with the IR pass, how well the IR cut of the MM works.)
Both R3Ds in one file 12.4MB:

I hold on the right side a Tiffen 87 (IR pass) and on the left a IRND 2.1 in the other image both overlap.
The IR cut of the IRNDs are so low, that they work as reducer. Even here they tint the image. I haven't tested all seven but the 0.3 is weaker for example.
(As I test each session one lens, and I had 3% left on the media, I thought to make that little test. The lens today was the Canon 24-70mm,L2.8 v1. Not the best lens, but it had IR markings on it, so I was curious.)
OK, without saying it is a good shot, I hope it will allow for some exploration.
P.S.: A quick preview, settings chosen to show the difference. ;o)
