It's completely intuitive to me since I learned about exposure when I was
shooting color slides on an OM-1.
An unexposed (but mounted) frame is black. As you add exposure, the frame gets
lighter. That's intuitive.
If you take the OM-1 to the beach and meter the sand/sky combination, you need
to *ADD* exposure to render the white sands as
lighter than neutral grey.
There's no exposure compensation dial on the OM-1, so you center the needle
with the aperture. When you center the needle with the
aperture ring, you can center the needle exactly since OM lens can be set
between detents (clicks). YOU CAN'T RELIABLY SET SHUTTER
SPEEDS BETWEEN CLICKS.
Then changing the shutter dial to a slower speed (overexposure) by one click
gives you precisely one stop of "overexposure" which
paradoxically is the "correct exposure" for the scene.
The needle will be above the zero space indicating that the scene will be
rendered on transparency film as something LIGHTER than
medium gray.

Now playing in my head: "You've got to get yer mind right, Luke. What we have
here is a failure to communicate."
