Examples — Variety

Unless otherwise noted, examples are processed straight from DPP with little or no post-processing, in order to show the image quality as produced from the camera.

This was taken in window light, with white balance set to Cloudy. At ISO 400, noise is remarkably high in this very demanding color medley. A hot pixel is seen at right (see crops). The red tomatoes have a chunky and coarse-looking noise. With strong colors like this (pure reds), noise is pronounced, something to be aware of. But even the light purpose on the spray bottle at left has visible noise.

I rate the noise here as barely acceptable for ISO 400, especially when the color areas are considered. It is a bit surprising, but that’s the nature of noise: it shows up in ways that are often not understood by simple by-the-numbers approaches.

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.
