Understanding Exposure and The Exposure Triangle


Exposure

Exposure is the amount of light that is recorded on your image sensor or film. There are three things that affect your exposure when you're taking an image - your aperture, shutter speed and ISO. These three things all affect the amount of light that your sensor capture, but they also have secondary effects.

Aperture controls depth of field.
Shutter speed controls motion blur.
ISO controls sensor sensitivity and noise in images.

Balancing these three things is the key to making good images.
