KipperTie’s IR Spectrum filter for RED is ‘Night-shot Mode’ for your DSMC2 system. Unlike its Full Spectrum sister, this filter passes only near infra-red beyond 720nm.
Developed over two years for our adventurous and high-profile natural history cinematography clients, this filter provides the ultimate in IR imagery with outstanding sharpness. The filter has anti-reflective and protective coatings and comes housed in a genuine RED swappable mount.
Version 2 of the IR spectrum filter improves anti-reflection by up to three stops, improves NIR transmission by around 10%, and has a more robust surface finish for easier handling.
Applications include:
Your Dragon will require the latest ‘swappable OLPF’ upgrade to have been installed. We recommend choosing the IR calibration in conjunction with this filter. Earlier firmware users, please use the LLO cal. Expect to see monochromatic colour and to work the image hard in Redcine-X to develop your look, including heavy curves.
With original DSMC cameras this filter has no ‘low-pass’ function. The image will be as sharp as your lens and sensor can resolve in combination. On a standard colour Dragon, you may see aliasing in extremely high frequency detail. Monochrome Dragon is immune to this in almost all situations.
Near-IR focus will be different according to the wavelength of the source, potentially resulting in split or haloed focus. For best results you must either filter at the front of the lens with IR glass to choose the part of the spectrum you want to work in, or control the wavelength of your IR sources carefully. Mixed sources of light can also show up the same focus issue.
Not all lenses perform equally in IR. Some will exhibit hotspots, some will have internal reflection and flare issues, and some very modern lenses may appear darker than expected in IR due to their sophisticated coatings.
