What Is Exposure In Photography? (A Beginner's Guide)

Exposure in photography is the amount of light that reaches the camera sensor when taking a photo. A correctly exposed image has captured the range of light in a scene correctly. An underexposed photo is too dark, with information not recorded in the shadows. An overexposed image is too light, with information not recorded in the highlights.

The exposure can be changed by changing the aperture, shutter and ISO. The relationship between the aperture, shutter and ISO is called the exposure triangle.

Photographers must understand exposure to ensure we know how to take photos correctly. You should get the right exposure every time you take a photo.
