That’s a long and winding explanation of … a lightmeter is calibrated to 18% grey …
Reading the article, Leica’s metering system is based on integral measurement.
- In case you want to mimic, set your Nikon D750 in the Custom settings menue → b5 → Center-Weighted Area → to choose from 8, 12, 15, 20 mm circle diameter or the average of the entire frame (check your manual pdf-file p.363 // printversion p.335).
I suggest to make up your mind from things you experienced / observered yourself over the years instead following “… I feel anger when I see cameras like a Nikon D800E with so many features that has nothing to do with light - because the camera then acts as a barrier in front of my eyes and take my attention away from creating the image my eyes saw.”
- Sorry to say so, but that is simply BS. Or do you think the Visoflex (the electronic successor of the mechanical Visoflex II / III) is any different?
