Monochrome Raw files
A monochrome raw file is captured by a monochrome sensor, that is, one without a Bayer matrix sensor. Each pixel of a monochrome raw file has a brightness value which needs no further interpretation (aside from a gamma curve). That is, no demosaicing involved, no false detail, no color aliasing with the result of maximum detail.
Monochrome sensors also are inherently higher sensitivity because there is no color filter over each pixel to absorb some of the light. So at the same shutter speed and aperture, a monochrome camera can be expected to record a significantly brighter image, thus affording a higher shutter speed or smaller aperture potential.

Diglloyd Infrared Photography covers cameras and lenses for infrared photography.
The coverage explains all the issues involved in shooting for monochrome and in infrared. It is not a review of any particular camera or lens, though many examples are included.
- Monochrome vs color cameras.
- Post processing for monochrome.
- 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.
