Leica M Monochrom

Shadow Noise and Highlight Detail at ISO 320

At ISO 320, the Leica M Monochrom has very low noise, but the true measure of useable dynamic range (exposure range) is whether detail remains workable when shadow areas are raised in brightness and/or highlights are brought within range.

A Leica MM DNG file that shows as blown-out in Adobe Camera RAW generally has some headroom available, due to built-in bias of the RAW converter. For this reason, the Leica MM histogram on the camera (a true RAW histogram) is a beautiful thing— one can know perfectly well how accurate the exposure is, at least with a little learning.

Camera histograms

Shown below are the histograms for the example image. The exposure was made to preserve most of the highlights while maintaining maximum shadow detail. A small amount of highlight detail was lost on the chair, as the red warning clearly shows (camera was set to 1% and 99% clip values, which control the blue/red warnings— nicely done).
