Exposure mode quick guide
Your Canon EOS 70D camera offers the following exposure modes, which you select via the Mode dial on top of the camera. The shooting mode determines how much control you have over exposure, ISO, and aperture. (Modes described as automatic scene modes in the table offer fully automatic photography, but some let you alter color and exposure slightly through the Shoot by Ambience and Shoot by Lighting or Scene Type features.)
