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 are typically numbers f/22, f/16, f/11, f/8, f/5.6, f/4, f/2.8

1/4000 at f5.6 ISO 800 for bursting water balloon

1/40 f111 ISO 400 for motion blur

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  seconds and the longest or slowest shutter speed is 1/xxxx seconds.

Examples of Shutter speeds (not in order) are 1/4000, 1/2000, 1/1500, 1/1000, 1/500, 1/250, 1/125, 1/60, 1/30, ⅛, ½, 1” 

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
