The Nikon D850 and the Z7II both have the same sized sensor - and supposedly different versions of the same sensor. In comparing Uncompressed 14 bit RAW files from the two cameras, the Z7II file is roughly 13% smaller - averaging 84 MB compared to 97 MB for the D850 image. The pixel dimensions of both cameras are the same. I've verified I am selecting the correct settings in the camera, but that does not mean Uncompressed files are the same. File size for 8-10 sample images varied less than 0.5%. I tested with a range of ISO settings including base ISO 64 for both cameras.

In this experiment, I took at picture of an old photographic Kodak Gray Scale target with my Nikon D810.
I metered the exposure manually on patch M, which is closest to an 18% reflectance middle gray.

Here is RawDigger main window (with the cursor sitting on the M patch) :

Still new to RawDigger and most of the concepts herein...
One of the striking features to me in the Histograms is the presence of an "EV scale".
I understand that EV stands for "Exposure Value", a legacy photographic term and related to scene Luminance.
What strikes me most is this "EV=0" reference?
Page 26 of 85 in the User Guide has a section of the "EV grid" where it is explained that "EV0" is automatically calculated from the image statistics: "Located at 3 stops lower than the maximum pixel value, rounded to the nearest power of 2".

Hi all. This is my first post since buying RawDigger. Could someone please explain to me in very basic language what the numbers mean in the statistics per channel box (see 2) and their relation to the over/under exposed stats (see 6). I'm finding this really confusing. Thanks so much. Paul.

Hello

Is there a way, to open a picture directly from inside Lightroom in RawDigger.

Thank you
