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/16, f/2.8, f/4, f/5.6, f/8, f/11, f/16

ISO 100 1/30 f 5.6

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

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

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

This setting goes from 100,200,400,800, ,1000,6500, on our cameras.
