Examples, Focus Stacking: Eastern Sierra (Nikon D850)

These examples look into using the Nikon D850 Focus shift shooting feature to create images impossible to create with an 85mm lens at any aperture. An 85mm lens affords very little depth of field, indeed very little room for focus error even at f/8.

If you don’t see anything highly unusual about these images in a detail sense, then ponder any image of anything remotely approaching the near-to-far-far depth of these examples. The depth of field seen in many of these images is equivalent to something in the f/32 to f/128 range or so—without any diffraction issues.

Focus stacking with an 85mm lens in the field is extremely difficult; it is time consuming and very demanding to get the stepping between frames just right, with a very high error potential. The Nikon D850 Focus shift shooting feature eliminates that problem.

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.
