Reviewing Concepts of Photogragphy

Aperture

Aperture is how wide the aperture of the camera opens, a wider aperture (as seen on the left) allows for more details of a shot to be shown in full detail while a more narrow aperture (shown on right) restricts the range of the shot that can be focused.

Shutter Speed

Shutter speed is how long the lens of the camera stays open and effects how the camera captures motion with a low shutter speed (right) causing objects in a picture to blur and drag where a high shutter speed captures objects in the split-second the photo was taken.

ISO

ISO is the measure for how sensitive the sensor of the camera is. Photographers use ISO to brighten up pictures without using flash but too high of an ISO (as seen on the left) can cause an image to appear "noisy" and grainy while a low ISO will make a photo come out clean and clear (right).
