How to Use Light Meters

With the use of a camera comes one common challenge; how to get the right photo exposure. This challenge is mainly caused by the improper setting of the light meter this resulting in poor quality pictures. A light meter measures the light intensity of a photo. It uses a digital or analog electric circuit to determine the appropriate shutter speed and f- number for optimal exposure.

Light Meter Types How to Use Light Meters

Light meters come in two namely incident and reflected light meters. The incident light meter uses an integrated sphere to measure the amount of light falling on a subject. The reflected Light meter, on the other hand, is calibrated devices that measure the intensity of light reflected by the camera subject/ scene.

Tips on Using Light Meters

  1. First set you Camera: Assuming that you already have your camera at hand, the first thing to do is to set your camera on manual mode. This you can do through locating the camera settings. Once this is complete, set your camera ISO and Aperture. Be careful with this as the ISO settings affect your cameras reception to light.


ISO Settings: A high ISO will make your camera too sensitive to light, while a Lower ISO will do just the opposite. This means the lower the ISO the clearer the resulting pictures. This doesn’t mean that you cannot use a high ISO. Most of the time, High ISO is used when shooting motion pictures.

Aperture: the Aperture determines how much light enters into the camera lens including photo depth and shutter speed.

  1. Input ISO number: After setting the ISO, put the ISO number into the light meter; the same should happen with your aperture. fashion photographer
