Cameras and exposure meters can take readings of the light levels in a number of ways, from basic to advanced methods. The most basic is Centre-weighted (CW) or average metering that takes a measurement from most of the image area.

Exposure Meters
An exposure meter is a device that determines how much light the film should receive to make a correctly exposed print that is neither too dark nor too light.
Exposure Meter
An Exposure Meter is a photo-sensitive device that measures the relative light source on a given subject by quantifying it in specific photographic expressions (foot candles, f-stops, etc.)

Exposure Meter An instrument with a light-sensitive cell that measures the light reflected from or falling on a subject, used as an aid for selecting the exposure setting. The same as a light meter.
Exposure meter (light meter). An instrument that measures the amount of light and provides aperture and shutter speed combinations for correct exposures. Exposure meters may be built into the camera or they may be separate instruments.
Exposure Meter A device that measures light to determine the combination of shutter speed and f/stop needed to make an optimum exposure. Exposure The total amount of light falling on the film or image sensor.
Exposure meter - device which measures the quantity of light reflected from or onto a subject [Just about all cameras have an exposure meter built into the camera...even a cell phone.
Exposure meter
Exposure meter is used measuring the amount of light coming in or reflecting by a subject.
EXPOSURE METER - An instrument containing a light-sensitive cell used to measure the amount of light reflected from or falling on a subject.
Exposure Metering Patterns: Many SLRs today have very sophisticated metering systems that analyze a scene and make calculations based on algorithms that have been pre-programmed into the camera.
Exposure Meter (Light Meter) A light-sensitive device that measures the light reflected from or falling on a subject, which is used as a reference for selecting the exposure setting.
Exposure meter
An instrument for measuring the amount of light (available or flash) falling on or being reflected by a subject, and converting this measurement into usable information: shutter speed and f stop.
Exposure meters and light readings
The precise level of available light is best measured by using a light meter. This can be either a hand held meter or one built into the camera.

exposure meter
an instrument that measures the intensity of light that is reflected from a subject or light that reaches the lens, indicating practical exposure recommendations and f-stop.
Exposure meter. Instrument that measures light intensities falling on, or reflected off, the subject, and indicates or sets corresponding camera settings (shutter and aperture).

Exposure meter
An instrument for measuring the intensity of light so as to determine the shutter and aperture setting necessary to obtain correct exposure. Exposure meters may be built into the camera or be completely separate units.
[edit] Exposure metering
Almost any scene of photographic interest contains elements of different luminance; consequently, the 'exposure' actually is many different exposures.

If built-in exposure meters are as sophisticated as camera manufacturers claim, why do people still get poorly exposed pictures? The truth is that while most built-in meters are fabulously accurate, they can be fooled.
Advanced camera exposure metering system. Nikons with this metering mode use a multi segment sensor a computer and an extensive scene data bank. A great method to insure a high success probability to correct exposure under most lighting situations.

Automatic Camera: A camera with a built-in exposure meter that automatically does the work of adjusting the aperture, shutter speed, or both for proper exposure.
Your camera or external exposure meter will want to set exposures that will render what it is seeing as about 18% middle gray. So, unless you want gray snow or gray colored black subjects you will need to override your meter for some subjects.
Matrix Metering system : An advanced exposure metering system using a multi-segment sensor and computer.
Again, rightly so because this would fool your camera's exposure meter into believing there is way too much light, resulting in an underexposed shot.
A typical handheld exposure meter actually provides you with two ways to meter. First, there’s reflected-light, or reflectance, measurement. That largely works the way the camera’s metering system works.
Every photographer is familiar with ISO speeds, those numbers we dial into our exposure meters and cameras so they can lead us-albeit, sometimes somewhat circuitously-to properly exposed images.
Creating one exposure metered for the highlights and another metered for the rest of the image is one simple way to gather the raw material to create a single "high dynamic range" scene by blending the two images in Photoshop.

As long as everything in the scene you are trying to photograph is average, the automatic exposure meter in your camera will take care of the exposure.
When attempting these three looks, use your exposure meter as a guide. Try to keep your mark in the center, right where your camera says it should be.
Had I been using an exposure meter, I would have taken an incident meter reading with the reflector in place, pointing the meter towards the camera. As it was, all I had to to was to do a test shot on my D30 and go from there.
Two types are used in exposure meters. A selenium cell generates electricity in proportion to the amount of light falling upon its surface. A cadmium sulfide cell offers a resistance to a small electric charge when light falls upon it.
Remember, your camera's exposure meter wants everything to be an even grey. To combat this, bracket a few exposures to see what works best for your particular lighting instance and then set your exposure compensation accordingly.
When a modern camera with a multi-segment exposure meter (Matrix) is used with a dedicated flashgun the correct exposure can be obtained for both the subject and background using 'Automatic Balanced Fill Flash'.
For total exposure control, especially in tricky lighting situations that can fool a camera's exposure meter, choose the Manual Exposure mode.
Because P&S cameras tend to have less well developed exposure meters and less manual control it is far more preferable to use print film rather than slide through them as any exposure variations can be ‘ ...
The snow covered mountains or landscapes will invariably fool the exposure meter built in your camera because snow adds to the overall brightness in the scene.
On the other hand, it is worth mentioning that flowers can often fool a camera's exposure meter. For instance, a white flower can fool the camera into thinking that there is more light than there really is -- resulting in an underexposed image.
But to exposure meters, which are biased toward the middle tones, clouds appear gray. To correctly photograph a cloud, you need to increase the meter's recommendation by ½ to 1 ½ stops.
Once you have the light just right, lock it in place. Exposure metering is critical. Underexposing a little bit is actually desired, because it tends to bring out richer colors and helps achieve a darker background.
Flash metering is done for the foreground subject, and the background is metered by the camera's regular exposure metering system. This can lead to the background being underexposed and dark if ambient light conditions are low.
Exposure meters measure the overall amount of reflected light from the subject. This level of light is then rendered as 18% gray in the picture. It will give a perfectly exposed image for scenes that contain mainly average gray tones.
If your camera does not have Shutter Priority Mode, you can use the exposure compensation feature if you have it. Normally identified by a plus/minus symbol, this feature allows you to "nudge" the camera's exposure meter.

As you can see colour negative film is very forgiving of exposure errors and will compensate for short comings in your exposure metering technique.
