M8.2 occasional strange histogram

[Rob-F]

Usually when I shoot my M8.2, I get the histogram I would expect from this, or any other camera. But sometime the histogram occupies only the lower 1/10 or so of the graph height. Just fairly flat across the bottom. It can happen when shooting a very average outdoor scene that presents no special challenges. I thought it might be the result of shooting a flat scene. but no. I tried shooting a flat gray wall. The histogram showed a full range of brightness values. I tried underexposure, overexposure; I can't make it happen on purpose.

Has anyone else gotten this?

Gnome inside the cameras does it. Remove bottom and shake vigorously until it falls out. Replace bottom ASAP as they are very fast.

Seriously, no. A grey wall should have a spike up the middle.

Does the pic record OK?

talk to Leica techs about it.

why guess ?

Well, I wanted to know if anyone else has noticed this. If so, then I would assume it to be a normal quirk of the breed. Never saw it from my Nikons, but it could be normal for the way Leica processed the data. I'll just let this run for a while and see how others respond. Most of my M8.2 shots are excellent, so I doubt there's anything seriously wrong.

I also notice that while the M8.2 histogram shows a shot to be properly exposed (with DNG selected), Aperture will indicate slight overexposure. Maybe I'll start a separate thread on that.

Aperture does it own tricks with the data off the sensor. The histogram is what the Leica jpeg records, not the Aperture (Lightroom, RawTherapee, RAWNinja, whatever) version.
