The 3 Basics of Exposure

Exposure is the action of letting a certain amount of light into the camera through the lens for a certain amount of time. The light then hits the camera sensor and the image is captured.

There are three basic elements to Exposure:
ISO - The Camera's sensitivity to light
Shutter Speed - The time (in seconds) that light is allowed into the camera
Aperture - How much light is allowed into the camera

We will learn about each of these elements of Exposure over the next few weeks.
