ISO Series

Images were taken in lossless compressed 14-bit mode. Not that it is probably pointless to use 14-bit and lossless format for higher ISO value, given that the noise overwhelms the precision. However, ISO 50 and 100 and perhaps ISO 200 can likely benefit from 14-bit lossless files. ISO 50 in particular seems exceptionally “clean”.

The sample crop chosen was not necessarily optimally sharp as it was well behind the focus point, but it is reasonably sharp for our purposes of evaluating loss of detail with higher ISO.

In-camera long exposure noise reduction was used (this applies beyond exposures of a few seconds); the D3x uses a form of dark-frame subtraction as do all the DSLRs.

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.
