How to use an exposure meter and the basics

A light meter is a tool that measures brightness. To take beautiful photos with a camera, it is important to know how much light there is. Using a light meter can give you a hint for taking photos with just the right brightness.

<Three important things when taking photos with a camera>

Shutter speed (how fast you can take a photo)

Aperture (F-number) (how much light passes through)

ISO (how strong or weak the camera is against light)

A light meter helps you think about the balance between these three.

It’s easy to use! !
① Turn on the light meter (switch it on!)

② Set the ISO

Set the ISO on the light meter to match your camera (e.g. ISO400).

③ Point it at the place you want to measure

Point the light meter at the place you want to know the brightness of. Usually, you point the white round dome-like part at the light.

④ Press the measuring button.

⑤ Check the numbers

Then the light meter will tell you, “The shutter speed should be 1/125 and the aperture should be F5.6!”
