Shutter Speed

The 3 camera settings that comprise the Exposure Triangle are Aperture, ISo and Shutter speed

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/1.5, f/2.8, f/5.6, f/8, f/11, f/16, f/22

The shutter speed settings are shown on the top left(left or right?) on the back monitor. 

Iso 200 27 mm f/4.5 1/5 sec

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