How do you measure incident light?

Incident light is the light that falls from the source onto the subject. It is usually measured with a hand-held instrument (often digital, these days) called an incident-light meter. Readings are usually taken from the subject's position, with the receptor-cell of the meter facing back toward the camera. Some incident-light meters are dedicated to that function. Others can measure "reflected" light (light that is reflected from the subject) and have a module for measuring incident light as well.
