Description
The Datacolor LightColor Meter is an incident meter. This means that it will measure the light falling on the subject or take general ambient measurements. To take a measurement, the LightColor Meter is best used placed near your subject to measure the light where your subject is located. For instance, if you are photographing a person, place the dome of the meter facing away from their face to measure the light.
The dome on the LightColor Meter has two positions, down and up. Use the dome in the up position to take a measurement from a wider angle. Press the dome down to take a measurement from a narrower angle.
For instance, if you want to take a measurement of the general ambient light you can use the dome in the up position for the widest area. If you want to measure the light falling on a person, press the dome into the meter.
The Datacolor LightColor Meter is not a spot meter. A spot meter can be used to measure the light that reflects off a subject. With a spot meter, you will point it where you want to measure and receive a measurement.
A camera's light meter is a spot meter, you use it to measure the scene or object you compose in the viewfinder. The LightColor Meter is an incident meter which you use to measure the light from the subject's perspective, not the camera's perspective.
