How to Use Light Meters in Photography

In Photography, light meters are used to measure the amount of light between a subject and camera. But since not all light meters are the same, some readings will be different, depending which type of light meter. By following some tips you can use your own light meters, either spot or in-camera, to create the perfect picture.

In-camera:

1. Select the right film speed. You can do this by using the film speed dial that is on the top of your camera. Remember that some in-camera meters will read the speed automatically.


2. Set up the meter to either of three settings: aperture, shutter speed, or automatic. Know that in the aperture setting, the light meter sets itself.  For the apeture setting you need to set the speed, and the automatic one sets both up for you.


3. Press the shutter button half-way down. This helps you take a reading and locks onto the subject. Remember not to push the button all the way down. If you hear a click then it means that you have taken a picture.


4. Use the meter readings to set either your shutter speed or aperture. You cannot do this with an automatic camera.

Spot Meters:

1. Adjust film speed or dial that is on top of the meter to the speed of the film that you are using.


2. Measure the light between the camera and subject. You can do this by pressing the button on top of the light meter. This will give you aperture and shutter speed.


3. Take a second reading from the subject back to the camera. 


4. Average the two readings, and then set the shutter speed and aperture on your camera.
