See the picnic table example also.
This example is underexposed by ~2 stops. But it is also at ISO 100. When I shoot my Nikon bodies, I trust that ISO 100 will yield robust, clean files that I can use for severe adjustments if necessary; I often shoot on the edge of light handheld.
Shown below is the scene as shot at ISO 100, 1/3000 second @ f/1.2. Aperture f/1.2 was chosen intentionally for a well-blurred background, to help reveal pattern noise. This is not artificial for real images; smooth tones such as sky, water, etc all have a propensity to show pattern noise. Or perhaps one just likes wide aperture landscapes.
There are three processing variations representing a reasonable RAW conversion for this scene:

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.
