Canon 5D S R
Sigma 24mm f/1.4 DG HSM A

Examples: Mt Conness Watershed (Canon 5DS R)

Examples from the Hoover Wilderness east of Yosemite.

Burned tree trunks amid young trees

Considerable contrast control used to convert this image and yet no contrast was added. ACR settings, Camera Profile = Adobe Standard, color fringing corrected.

This shot f/13 was dulled somewhat by diffraction, but diffraction-mitigating sharpening perked up the micro contrast. The lighting was extremely contrasty due to the bright sky and nearly black tree trunks, and yet the 11-24/4L delivers exceptional contrast with no sign of flare or veiling haze. Image quality of the 5DS R held up very well here in spite of the push and raising the shadows, due to a near-perfect ETTR exposure (could have taken ~1/2 stop more exposure).

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.
