A light meter is a device used to measure the amount of light. In photography, a light meter is often used to determine the proper exposure for a photograph. Typically a light meter will include a computer, either digital or analog, which allows the photographer to determine which shutter speed and f-number should be selected for an optimum exposure, given a certain lighting situation and film speed.
Light meters are also used in the fields of cinematography and scenic design, in order to determine the optimum light level for a scene. They are used in the general field of lighting, where they can help to reduce the amount of waste light used in the home, light pollution outdoors, and plant growing to ensure proper light levels.

Famous quotes containing the words light and/or meter:
“If you wish to grow thinner, diminish your dinner,
And take to light claret instead of pale ale;
Look down with an utter contempt upon butter,
And never touch bread till it’s toasted—or stale”
—H.S. (Henry Sambrooke)
“His meter was bitter, and ironic and spectacular and inviting: so was life. There wasn’t much other life during those times than to what his pen paid the tribute of poetic tragic glamour and offered the reconciliation of the familiarities of tragedy.”
—Zelda Fitzgerald (1900–1948)
