Shutter Speed blog post

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/22, f/16, f/11, f/8, f/5.6, f/4, f/2.8, f/2.

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

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

Examples of Shutter speeds (not in order) are 1/4000 seconds 1/2000 seconds 1/1000 seconds 1/500 seconds 1/250 seconds 1/125 seconds 1/60 seconds

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

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

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