The Exposure Triangle

The Exposure Triangle is at the foundation of photography. More than just a representation of aperture, shutter speed, and ISO, it is a concept, the understanding of how your camera captures light. An exposure triangle is also a tool, a usable chart showing you how to adjust your exposure to capture the image you desire.

Exposure in photography is all about light and how your camera captures the light. Every exposure is a relationship between aperture, shutter speed, and ISO, and there are many ‘correct exposures’ available to you by varying this relationship. Introduction to the Exposure Triangle will be the gateway that allows you to go from snapping pictures to creating images. Learn how to take more control of your camera.
