Chroma noise (color speckling) can be reduced effectively while preserving image detail.

Adobe Photoshop CC 2015, Adobe Camera Raw 9.1 (441).
ACR settings, Camera Profile = Camera Portrait.
The crops here are from the ISO 12800 image on the noise comparison page, but using Adobe Camera Raw with Camera Profile = Camera Portrait, which provides a much more accurate rendition than Camera Profile = Adobe Standard, due to the ACR Adobe Standard bug.

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.
