Examples: Nikon D200–IR

I used a D200-IR briefly. It was first converted by removing the factory-installed sensor glass. This made the camera a “full spectrum” camera, sensitive to ultraviolet, visible light and infrared.

With the sensor glass removed, it is no longer possible to focus to infinity. Though I didn’t try all my autofocus Nikkors, none of the several I tried could autofocus accurately with either conversion (no sensor glass or replacement sensor glass). A few lenses, like the 85mm f/2.8D PC-Micro-Nikkor did focus reasonably close, but with a touch of backfocus. Manual focus would be required for most subjects where a specific plane of focus is required; little slop is available on a high-resolution camera like the D200, even at f/8 and certainly not at f/2 or f/2.8.

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.

View an overview of infrared as well as filter spectral transmission plus examples from an optimal lens.
