Shutter Speed Blog Post

The 3 camera settings that comprise the Exposure Triangle are Apeture, Shutter 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

1/4000 at f5.6 iso 1600 for popped balloon

to largest openings) are typically numbers f/16, f/11, f/8, f/5.6, f/4, f/2.8, f/2

1/4000 f5.6 Iso 1600 for Popping Water Balloon

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 seconds and the longest or slowest shutter speed is 30 seconds.

The third setting ISO controls the camera’s sensitivity to light.  1/40 f22 ISO 400 for motion blur

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
