Shutter Speed Blog

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 are typically numbers f/32, f/22, f/16, f/11, f/8, f/5.6, f/4, f/2.8, f/2, f/1.4. The shutter speed settings are shown on the top right of the back monitor. Expressed as fractions of a second, the shortest shutter speed is 1/4000th seconds while the longest is 1/30 seconds. The third setting ISO controls the camera’s sensitivity to light. This setting goes from 100, 200, 400, 800, 1600, 3200, and 6400 on our cameras. To center the meter, we can either change the Aperture, Shutter Speed, or the ISO

In our first photo with the water balloon popping, we can see I utilized these settings. On this gloomy day I used 4000 ISO, 55mm Focal Length, an Aperture of f/5.6, and a fast Shutter Speed to capture the exact time the water balloon popped at 1/4000th of a second.

In our second photo with the ghosting effect, we can see I utilized these settings. I selected the ISO at 400, Focal Length at 37mm for a crisp result, and used a Aperture of f/10. The only difference with the result is the change of Shutter Speed which allowed me to create this " ghosting " at a slow 2 seconds.

In our third photo with the motioning elephant, we can see I utilized these settings. I selected the ISO at 400 as with my other, a crisp Focal of 22m, and a Aperture of f/3.5. The motioning comes from the change of Shutter Speed at a very slow 1/30th of a second. This allowed for the background to appear as it is motioning.

In our final photo with myself as the motion, we can see I utilized these settings. I first, selected a ISO of 400, Focal of 22mm, Aperture of f/3.5, and changed the Shutter Speed to create the motion background effect. I changed it to another slow 1/30th of a second.
