Shutter Speed blog post

The 3 camera settings that comprise the Exposure Triangle are F/5.6, 1/4000 sec and ISO 3200.

On the back monitor of our Canon DSLR cameras, the aperture setting is displayed with “F” followed by a number.  

1/4000 at f5.6 ISO 800 for bursting water balloon

Apertures (from smallest openings to largest openings) are typically numbers f/25, f/22, f/20, f/18, f/16, f/14, f/13, f/11, f/10, f/9.0, f/8.0, f/7.1, f/6.3, f/5.6, f/5.0,f/4.5,f/4.0

ISO 1600 1/1000 f5.6

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.

The third setting ISO controls the camera’s sensitivity to light.  1/30 f11 ISO 200 for motion blur

This setting goes from 100,200,400,800,1600,3200, on our cameras.

To center the meter on our cameras, we can change the aperture , ISO 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.
