Shutter Speed Blog Post

1/1600 at f5.6 ISO 1600

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

ISO 400 2.0 Sec f9.0

ISO 400 f3.5 1/30

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  1/4000 seconds and the longest or slowest shutter speed is 1/30 seconds 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 change the aperture, shutter speed, or the ISO.
