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

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

Apertures (from smallest openings to largest openings) are typically numbers f/29,f/25, f/22, f/16, f/11, f/5.6, f/4.5.

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

Expressed as fractions of a second, highest shutter speed on our cameras are 1/4000second and the slowest shutter speed is 30.

The third setting ISO controls the camera’s sensitivity to light.

To center the meter on our cameras, we can either  change the  aperture , shutter speed or the Iso
