Light meters measure the amount of light. Then, for a given film speed, (ISO) they calculate what settings the camera needs to be on to create a perfectly exposed photo.Light meters are designed to measure for middle gray.
This means that the camera after choosing a middle gray will create highlights and shadows based on the where the middle gray lies.
Most digital cameras now days have built in light meters, that are activated when pressing the shutter 
half way down. (at the same time you are focusing, you are reading the lighting)
•In regular lighting the camera does a pretty good job of metering correctly.

However, sometimes lighting plays tricks on the camera.
This is often found when there is a really bright background.
The camera meters for the sky, leaving the subject dark.
We used our camera meter to purposely meter for the computer screen, and then for the light on our partners skin. As you can see, when the camera rereads the light on our partners skin, they become visible to us, even though the room was dark.
It is not always necessary to meter, but when the situation arises, it can make all the difference.
