The 3 camera settings that comprise the Exposure Triangle are shutter speed, ISO and aperture

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/22, f/116, f/11, f/8, f/5.6, f/4, f/2.8

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

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 change the shutter speed, aperture or the ISO.

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.
