Aperture – a hole within a lens, through which light travels into the camera body. The larger the hole, the more light passes to the camera sensor. Aperture also controls the depth of field, which is the portion of a scene that appears to be sharp. If the aperture is very small, the opening is large and the depth of field is short, while if the aperture is large, the opening is small and the depth of field is long. In photography, aperture is typically expressed in “f” numbers (also known as “focal ratio”, since the f-number is the ratio of the diameter of the lens aperture to the length of the lens). Examples of f-numbers are: f/1.4, f/2.0, f/2.8, f/4.0, f/5.6, f/8.0.

You will need to take:

3 photos of a Portrait - using a high, medium and low Aperture setting

3 photos of a Landscape - using a high, medium and low Aperture setting

3 photos of an Object - using a high, medium and low Aperture setting

Remember, something needs to be in the foreground in order for the aperture to work. Be creative with your subjects. Take more than required and choose the best!

Good Luck.

Turn your camera to "A" aperture priority mode

The Aperture is the center circle on your cameras display. Shown here is an aperture of f3.5, this means the hole of the lens is large, letting in lots of light and focusing only on those objects that are closest to you

Spin the dial by your thumb to change the f-stop. You will notice that the shutter speed and iso change automatically to compensate for the amount of light coming through the lens.

Here we see the same picture taken at f-stop 3.5, 8, and 22

To turn in photos, have all apertures of one subject in a single image. To do this:
