This example using the Nikon D800 converted to 715nm infrared.
Converting a camera to infrared that allows false color rendition makes it a flexible tool, because a filter can be applied for “seeing deeper”: cutting off shorter wavelength infrared.
As shown below, the filter on the converted D800 cuts off at 50% at 715nm.
Applying a B+W 093, the cutoff becomes 830 nm, eliminating a big chunk of short wave infrared as well as any lingering deep red. This results in a up to a 2-3 stop increase in exposure time, depending on the scene.

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.
