Sharpening Leica DNG and RAW Images

This discussion applies in general to Leica M, Leica S DNG files, but also any other RAW files such as Sony NEX ARW files.

Unlike film, which is an analog medium with built-in acutance (edge sharpness) enhancment, all digital capture sensors inherently blur edge sharpness by the discrete sampling of the image. For example, a sharply defined black/white edge falling over two photosites is rendered as gray on those two photosites— averaged from black or white to gray on both photosites.

To restore the natural acutance with a digital image, some level of sharpening is required. Any presentation of images with no sharpening is an unrealistic representation of sharpness which has not accounted for the sensor characteristics.

Diglloyd Guide to LEICA contains in-depth coverage of Leica M system cameras and lenses, with additional coverage of Leica M Monochrom, Leica Q.

Special emphasis is placed on Leica M lenses and certain Zeiss ZM lenses.

  • 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 the Summilux/Summicron/Elmarit choice and/or Zeiss ZM.
  • Make better images, a sort of “cheat sheet” saving yourself months or years of ad-hoc learning. Processing parameters are discussed and shown.
  • 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.
