This page demonstrates the potential for making color images from a monochrome camera.

It is far from optimal to have to screw/unscrew filters (slight movement of camera no matter how locked down plus subject/lighting change) and shoot while there is wind, but that is what I did. Specifically, I shot three frames, one frame each with: B+W Blue KB15, B+W Green 061, B+W Red 090, refocusing for each filter (in retrospect a mistake, since the lens breathes just a little which in outer zones puts things a fractional pixel out of registration).
The filtration allows for unusual separation of red/green blue that is distinctly different from a Bayer matrix color camera, whose R/G/B pixels have strongly overlapping wavelength sensitivity. It would also be possible to use other filters and also to create quad-channel color images.

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.
