The 3 camera settings that comprise the Exposure Triangle are shutter speed, aperture, and ISO.

On the back monitor of our Canon DSLR cameras, the aperture setting is displayed with “F” followed by a number.

The shutter speed settings are shown on the top left on the back monitor.

Examples of Shutter speeds are 1”, ⅛”, ½, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, 1/2000,1/4000
