Dear Roger, Based on your gray card NEF: You are in 14-bit mode, maximum is 2^14-1-black level (600) = 15873; average on the card (and the card seems to have some rather strong imperfections) is 1181 (you can check with RawDigger, trial version is enough). That puts the exposure at log2(1181 / 15871) = 3.75 EV below clipping; the camera is calibrated to produce midtone 3.35 EV below clipping, that means the exposure is 0.4 EV below the midtone. Nothing dramatic so far, provided that the card has a lot of wear and tear on it, it isn't shot out of focus, and not at an angle as it should be (see http://www.zonephoto.it/images/pdf/kodak-grey-card1903061.pdf ). The result is mathematically inconclusive - but from my experience I would be expecting something like the numbers above, given how the shot was taken, and would say that metering is calibrated OK. Of course, if you could re-shoot we will be able to come to a more definite conclusion. On Jun 21, 2019, at 6:03 PM, Roger Breton via colorsync-users wrote:

I will get to the Gray Card NEF in a few minutes, Ilah, but I thought I would try turning on Image quality = NEF + JPEG in the camera shooting menu?

And I got very different results? See this link: https://1drv.ms/u/s!AkD78CVR1NBqkLVK68wxOJ6dhvv2nQ

On the left hand side is the JPEG opened in Photoshop as usual, and on the right hand side is the RAW, opened in CameraRAW. The only thing that I could say is the Histograms are very different, this time, extending well into the highlights...

Thanks for you guys patience and help. I'm trying to contact Nikon tech support...

Best / Roger

I just tried with ViewNX2 and it is still too "dark"? So it is not coming from CameraRAW -- good news 😊

ViewNX2 link is here: https://1drv.ms/u/s!AkD78CVR1NBqkLVIL-cOCJBYIX0LuA

CameraRAW link is here: https://1drv.ms/u/s!AkD78CVR1NBqkLVJgBzv-yK7ygFD7g

The histograms are not lying, this is under-exposed.
