Q2 Monochrom, Histogram and JPEG Contrast

[Mark II]

I have just bought a Q2M, and I notice that the JPEG contrast settings appear affect the histogram. Does anyone know what the optimal JPEG setting is so that the histogram accurately represents exposure in the DNG prior to any processing?

I would like to reply on the histogram for exposure since the Q2M overexposure blinking is not configurable, and quite annoying in use given the black/white flashing. On the M10 you can program the thresholds for under/over exposure and these are shown in colour on the live-view display - something that would works especially well with a monochrome sensor.

Of course the jpg settings affect the histogram. It will never be100% accurate for the DNG, as it is based on the jpg. If you want to avoid blown out highlights avoid a spike in the histogram on the righthand edge. However you have a bit of a safety margin.
It would be difficult to produce coloured flashing as the processing in the camera is monochrome and not a conversion. The LCD can produce colour, though.
