Shutter Speed

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 are typically numbers f/32, f/22, f/16, f/11, f/8, f/4, f/2

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, 1/2000, 1/1000, 1/500, 1/250,1/125, 1/60, 1/30, 1, ⅛, ½ seconds and the longest or slowest shutter speed is 1/30 seconds.

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

This setting goes from 100,200,400,800,1600,3200,6400 on our cameras.

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