Well, I put up some links, and I'm perfectly happy with them.

For myself, I suggest that ISO and Kodak trumps 'Cambridge in Colour' and Adobe. Another bit from the Kodak Sensitometry workbook, in the glossary they give, for people that are unfamiliar with the terms:

From when ISO was not a parameter that could be set in-camera, but was set by the film type (and adjustable by alternative processing.

Yet when they started producing digital cameras:

"Setting ISO Speed

The ISO setting controls the camera's sensitivity to light. Use a lower ISO setting in brightly lit scenes; use a higher ISO setting for low-light scenes.

NOTE:ISO settings are available in Auto, Landscape, and Close-up modes (unless Long Time Exposure is set). Higher ISO speeds may create a picture that is "noisier" than a picture taken at lower ISO speeds."

The definition of exposure hasn't changed since digital became a thing. And ISO says that ISO isn't a component of exposure. If ISO isn't what ISO says it is, what is it?

Your continued arguing against the facts is pointless. It seems that you just can't bear to admit that you got it wrong.

ISO is a component of exposure.

Or you can propose another term for "exposure settings" other than "exposure settings".

The facts, of course, are clear; there are numerous sources that describe the exposure triangle and exposure settings.

When you look at an image on DPR, they display focal length, shutter speed, aperture, ISO, and exposure compensation.  Focal length is not an exposure setting, but the rest of them are.

Your insistence to the contrary; there is little value in your definition because it is insufficient.
