Incident Light meter Readings

Incident light meters measure the light falling on the subject instead of the light reflected from the subject and the exposure is calculated from this reading. An incident meter is held as close as possible with its inva cone aimed toward the camera.It receives light from the same direction and at the same intensity as the subject does. This is translated into an average 'middle grey' exposure setting. The main advantage of the incident meter reading is that it cannot be fooled by subject tones. Its main disadvantage is that it cannot read them.
