Aperture Series: Collapsed Ranch House at Sunset (Nikon D810)

This scene examines a typical scene for a 24mm whose structure includes a immediate foreground substantial detail at mid range, and receding contextual details at a greater distance.

Choice of focus

There is no way to make such a “deep 3D” scene sharp near to far without stopping down quite a bit, and invariably a judgment call has to be made on which area (distance) of the subject to favor.

Knowing that there is a forward field curvature at the periphery and that there is also a goodly amount of foreground, focus for this scene was placed on the leading edge of the building—counting on stopping down to deliver sharpness over the whole building as well as the foreground which benefits from the forward field curvature. The far distance at the periphery can be expected to require stopping well down, but because it serves mainly as context, it is not a consideration for choice of focus distance.

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.
