There has been some chatter about deliberately underexposing the M9 at a lower iso and then pushing the exposure in post to get better noise results, and questions have been asked, since the Monochrom shares the same base sensor as the M9, if that would work with it. The answer is yes and no. It is doable, but (to my eye), there is no appreciable reason to do it. There is a slight (approx. 1/4 stop) gain in the highlight side of the histogram, but the overall noise is the same, and when fully processed, no real differences. It does demonstrate how much detail is available in the Monochrom shadows; a 5 stop push on the underexposed image was just fine. #2171: iso 10000, -.3 stop exposure compensation, no other Lightroom adjustments. #2172: iso 1250, -.3 stop exposure compensation, + 3 stops exposure added in Lightroom. #2171A: Additional post processing in Lightroom to look correct (in my opinion). #2172A: Additional post processing in Lightroom to look correct (in my opinion).
