Leica M10 Monochrome Long Exposures at ISO 160

See also Leica M10-R long exposures.

This page assesses the long exposure performance of the Leica M10 Monochrom at ISO 100.

All frames used long exposure noise reduction (so a 16-minute exposure takes 32 minutes total), but no chroma noise reduction or luminance noise reduction was used for raw conversion.

360 seconds (6 minutes)

Adobe Camera Raw View ACR Settings. The Raw Digger histogram shows an optimal ETTR exposure, so this is a best-case performance. Temperature was also highly favorable to keeping sensor noise low, around freezing.

  • 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.
