- What is the light meter?
- A light meter (a.k.a. exposure meter) is a light-sensing device and is crucial to creating a high-quality photograph.
- Why is the light meter crucial?
- With a light/exposure meter, the photographer can be confident that he or she will consistently achieve good results with accurate exposure, which is fundamental to producing a high-quality photograph.
- There are 2 different types of light meters:
- Hand held light meter
- Light meter built into your camera (to know when you have achieved the proper combination of lens and shutter-speed settings, look at either a needle or diode display in the viewfinder or an LCD display on top of the camera)
- Light meter built into the camera (the type of meter we are using in Basic Film class):
- More specifically, what does it measure?
- It measures the sensitivity of the light compared to the ASA that the photographer has his or her camera set on (this number is whatever speed is indicated on the film box).
How? When metering a scene, the light meter will see a very bright part of the scene (i.e. a bright background behind a subject in shadow), and will incorporate that bright part into the overall scene.
