Examples in Infrared (Nikon D800, 715nm)
These examples on a modified Nikon D800. Conversion by MaxMax.com of Nikon D800 for infrared use.
- 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.
Spectral transmission
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 DAP is DSLR-oriented, but also contains workflow and other topics. Much of the focus is on Canon and Nikon but also Pentax and Pentax medium format.
Special emphasis is placed on lens evaluation, focusing on Canon and Nikon and Sigma lenses, but with a few others like Rokinon/Samyang.
- Make better images by learning how to get the best results right away.
- Save money by choosing the right lens for your needs the first time, particularly some of the new Sigma Art lenses vs Nikon and Canon.
- Workflow discusses image organization, raw conversion and post processing. Many examples show processing parameters for direct insight into how the image was converted.
- Jaw-dropping image quality found nowhere else utilizing Retina-grade images up to full camera resolution, plus large crops [past 2 years or so].
- Real world examples with insights found nowhere else. Make sharper images just by understanding lens behavior you won’t read about elsewhere.
- Aperture series from wide open through stopped down, showing the full range of lens performance and bokeh.
- Optical quality analysis of field curvature, focus shift, sharpness, flare, distortion, and performance in the field.
