Shutterspeed

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/32, f/22, f/16, f/11, f8, f/5.6, f/4, f/2.8, f/2, f/1.4

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

1/20 f/8 ISO 1600 for motion blur

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.

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