"Shutter Speed"

The 3 camera settings that comprise the Exposure Triangle are the Shutter Speed, Aperture and ISO

ISO 200 49mm F5.6 1/400 sec : Water container SPLASH

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/4.0, f/4.5, f/5.0, f/5.6, f/6.3, f/7.1, f/8.0, f/9.0, f/10, f/11, f/13, f/14, f/16, f/18, f/20, f/22, f/25.

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 30" seconds and the longest or slowest shutter speed is 1/4000 of a seconds.

Examples of Shutter speeds are , 1”, ½, ⅛”.1/30, 1/60/ 1/125, 1/250, 1/500,1/1000,1/2000, 1/4000.

ISO 1600 42 mm F/8.0 1/60 sec : Spinning with Thor

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 shutter speed or the F-Stop (Aperture).
