The metering mode button is normally located on the top of DSLR cameras.
While digital and film cameras are different in many ways, they all share one similar item: a light meter. Light meters in cameras will meter light in a couple of different patterns. They can meter a very small point of a scene -- called spot metering -- or they can meter across the entire scene and come up with an average exposure. This type of metering is referred to as average metering or evaluative metering.
Instructions
1. Turn your digital camera on and press the metering button. Select "Average" or "Evaluative" metering mode. Depending on the make and model of the camera you are using, this button is usually located on the top of most DSLR cameras. Consult the owner's manual for your specific model.
2. Hold the camera to your eye and compose the scene either by adjusting the zoom function of your lens or by adjusting the camera's shooting position until you are satisfied with the picture.
3. Press the shutter release half way down to activate the camera's metering system. The built-in meter will read the amount of reflective light that is transferred through the lens and will calculate an exposure that should properly expose the entire scene.
4. Press the shutter release the rest of the way down to take the picture.
