Aperture Series @ 180mm: Rush Creek Waterfall (Nikon D810)

This extreme distance places a premium on field flatness (minimal field curvature), gives us a good look at corner performance, and also shows off any propensity to color fringing.

This scene is a difficult challenge for any lens due to bluish atmospheric haze; a polarizer was used at maximal effect to cut the haze down. I usually don’t like the dulled look that comes from using a polarizer but it was all but mandatory here.

The Sony FE 70-200/2.8 GM OSS failed miserably on this scene (not shown here)—with grossly inferior results.

Rush Creek Waterfall @ 180mm

The waterfall is Rush Creek grossly overflowing its usual course. A steady stream of helicopters flew up to the dam just out of sight in the valley—apparently at risk from extreme flows—and it wasn’t even a hot day.

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 28 megapixels filling up to 5K display, 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.
