The Leica MM Monochrom offers a base ISO is 320, but in the field especially as a journalistic style tool it is often the case that images are made that are underexposed and need a push.
Especially if a lens is shot wide open, optical and natural vignetting can deliver 2-3 stops less light into the corner areas. The Leica MM lens correction presumably adjusts the RAW file for this as does the M9/M9P.
This examination of “push” uses the images from the doll comparison.
The exposure was at as bright a level as possible without blowing out highlights, as per the Leica MM histogram. Furthermore, the aperture chosen for this example is ƒ5.6, so that any vignetting that remains is only natural (unavoidable) vignetting. In short, there could have been no brighter exposure possible for this scene without blowing highlights.

- 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 28 megapixels filling up to 5K display, 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.
