This example confirms and supplements the Macbeth color checker card example.
UPDATE 13 May 2016: This is what I heard from Adobe: “Known issue. It is fixed in the next ACR update. High ISO dngs shots with super resolution”. That sounds good, but both my examples are at ISO 100, the lowest available ISO.
SuperRes pixel shift mode (“SR-PSM”) merges 4 exposures into one raw file. The raw converter must then take those 4 exposures and (somehow) create an RGB pixel for each pixel in the image.

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.
