In reality, concerns about noise are generally much ado about nothing, with digital trouncing conventional photographic film, at least with digital SLRs. Conventional film with its inherent graininess was long accepted, and there wasn’t a thousandth as much concern about it—it just was a fact of life. There are two factors which are likely responsible for the hubbub about digital image noise:
- The increase in the number of megapixels in consumer digicams, together with increasingly tiny sensors, both of which contribute to higher levels of noise per pixel due to ever tinier photosites;
- The steady improvement with digital SLR sensors, staying the same size or growing larger, not smaller. Improvements make people expect more.
Infrared is somewhat more forgiving of noise, especially if the image is converted to grayscale, where color noise turns into a film-grain-like noise. In fact, noise can be appealing and add to the mood of the image.

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.
