Shutter Speed

ISO: 800 55mm f/5.6 f/2500 sec

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/2.8, f/4_, f/5.6_, f/8_, f/11_, f/16, f/22_

ISO: 100 18mm f/22 1/30 sec

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.

Examples of Shutter speeds (not in order) are ⅛”, ½, 1”,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,_3000_, on our cameras.

To center the meter on our cameras, we can either  change the aperture or the shutter speed.

Finally for the 3rd picture, we learned how to securely fasten a camera to a tripod to take a picture showing a ghost-like image.
