Shutter Speed

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.  

ISO 1600 f/5.6 1/4000”

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

ISO 200/ f/22 / 1/30"

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 seconds.

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

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.

For this photo I made sure to balance my meter so it was center. I made my ISO 400 and f/22 so that the photos wouldn’t be to dark I made it 2 seconds on shutter speed so I could get the blurry ghost effect.
