Dark Side of the Camera
Are you also the Executive Producer (aka footing the bill) as well? If so, nice job on the costumes and vehicles.
Quick tech question. Do you place the IR filter in front of the Variable ND? Can you post a link to which IR filter you use?
Thanks!
Yeah, I'm producer, director, DP and editor - typical one man show
The filter is called HELIOPAN - Digitalfilter, BLF 1x, LW -0
It also doubles as a UV filter and sits on top of the ND.
This filter has been especially designed for imaging with digital sensors since
they have a significantly higher sensitivity in the IR area then film material it
blocks both disturbing UV and IR light. The result is improved color separation
and sharpness.
The UV protection blocks UV radiation in daylight. In addition colors are
improved especially in the blue and red channels. Since artificial light contains
especially high IR radiation the filter ensures better control of the blue
channel. This dichroic coated specialty filter should not be used with extreme
wide angle lenses.
Here is the only English link I found: http://www.heliopan.de/Heliopan-Filters.pdf
Normal hot mirrors (tru cut) are made for film and are useless on digital video cameras, since they start to cut at 720 nm.
Most sensors already have a filter wit that specs anyway.
What you want is a filter that starts in the "far red" spectrum at 680
