I'm sorry, but the human eye and photographic processes ARE NOT

You're correct that a sensor can only detect what is being thrown
at it; however for a given scene if a given amount of light falls
on it, an incident reading of that light indicates what will be
detected by the recording sensor (at that setting). Some objects
may reflect an amount of light that falls below (or above) the
latitude of the sensor, and they will be unrecorded or burned
out... but that's an issue with film (sensor) not the meter.


Incident metering wouldn't detect the light that will be detected by the
recording sensor UNLESS
the recording sensor is located at the subject pointed toward the camera
position. Correct? And
locating your camera at the subject and pointing away from it would be quite
a different picture.


Cheers,
Alan.
