Canon Camera Features: Aperture, Shutter Speed, and ISO

So i thought I'd write a post about three very important features on Canon Cameras; Aperture, Shutter Speed, and ISO. Below I discuss how to use them to take better photo's.

Aperture 

Aperture controls how much light enters the camera through the lens. The more you open your aperture, the less depth of field. The more closed your aperture, the more depth of field.

Example:

Open Aperture - lower f-stop numbers like: f/2.0, f/2.8, f/3.5

Closed Aperture - higher f-stop numbers like: f/11, f/16, f/22

Shutter Speed

Shutter speed controls how long the light entering the aperture exposes  the sensor. The faster the shutter speed the sharper the image. Remember, You can handhold the camera when your shutter speed is 1/focal length. Shooting at slower shutter speeds requires a strong stance, steady hand , and easy breathing. Sometimes even holding your breath.

Example

Slow Shutter Speeds - 1", 1/20, 1/50,

Fast Shutter Speeds: 1/125, 1/500, 1/1000

ISO

ISO numbers measures how sensitive the camera sensor is to light. Higher ISO numbers (800, 1600+) mean the camera sensor is more sensitive to light.
