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

f/60 at f/9.0 ISO 1600

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 seconds and the longest or slowest shutter speed is 30 seconds.

Examples of Shutter speeds (not in order) are1/1000 , 1”, ⅛”. 1/60/ 1/500, 1/4000, 1/125, ½, 1/30,1/2000,1/250, (arrange these in order when you put them in your blog post)
