Exposure Triangle: Making Sense of Aperture, Shutter Speed & ISO

Exposure is the most critical concept in basic photography. It is a concept you must understand and master in the first few months of the learning process.

In photography, exposure defines how a photo is recorded by a camera and how much light is captured. If you let the camera capture too much light, the picture will be too bright or overexposed. If the camera sensor doesn’t capture enough light, the photo will be too dark or underexposed.

The photographer’s job is to strike a perfect balance by capturing the right amount of light to produce well-balanced images. To control the exposure in photography, you must understand its three main components—aperture, shutter speed and ISO. Together, these form the Exposure Triangle.
