Taken at relatively close range in a shaded mountain canyon under bluish light. The color has intentionally been left cold (bluish) by conversion using Daylight color temperature.
Adobe Camera Raw 8.2(94): 5000° K, Tint = 0, Camera Profile = Embedded
Green Aspen trunk
This example shows several useful things about the optical performance.
Observe that wide open sharpness is already excellent, though somewhat low in contrast. It is even sharper than one might expect. There is a reason: lenses are nearly always corrected optimally for green light (best MTF for green). With the green aspen trunk, green transmission dominates, thus minimizing the hazy effect caused by violet fringing (secondary color). The sensor is also at its best resolution for green, a happy marriage.

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.
