- The sensor cover glass was removed and replaced with new glass of appropriate thickness that passes infrared and blocks visible light.
- The modified D800 now “sees” only infrared light starting at around 715nm.
- Any and all lenses can be used since the filtration is internal.
Infrared photography properly begins around 715nm, with the range of 715-760nm affording “false color”: the R/G/B photosites respond differently to infrared light (differential transmission). Starting around 760nm, all of the R/G/B photosites go transparent to infrared, thus the image becomes pure monochrome (the photosites all see the same luminance).

Diglloyd Infrared Photography covers cameras and lenses for infrared photography.
The coverage explains all the issues involved in shooting in infrared, which do not change. It is not a review of any particular camera or lens, though many examples are included.
- Guidance on workflow for infrared, including black and white and channel swapping for false-color images.
- How infrared renders, and why certain spectral cutoffs matter: false color vs black and white.
- Image quality issues to be on the lookout for in infrared.
- Numerous lens evaluations in infrared.
