against a strongly lit background, the background will be totally
whited-out, with buildings and other objects blurred. In this case,
the AUTO KNEE function reproduces the background clearly.

The subject is a person inside a car or building, and you also
want to capture the background visible through a window.
•
The subject is a high-contrast scene.
