Setting the aperture on your DSLR camera is an easy function to change.  The video below will take you through the process of how you can dial-up an F-Stop on your camera. We will also explain how the aperture works and what those F-stop numbers mean. It is important that you practice change the aperture settings on your camera as it is a function that is commonly used.

Depending on your DSLR camera, you will change the F-stop using one of the following ways:

Option 1

Check your user manual, if you do not have two dials on your camera, the chances are that you will need to find the exposure compensation button.  You will need to press and hold this button down whilst rotating the dial on your camera to change the F-Stops.

If you have two dials, the chances are as you rotate one of them your F-Stop numbers will change. Canon cameras have a flat dial on the back of the camera that works and rotates as a dial.  One will change the shutter speed, the other is for the aperture.

To understand the F-Stop number, you need to add a 1 in front of them.  F-Stops are fractions. For example, 4.0 is 1/4 of the opening size.  The large numbers mean a smaller aperture size like F16 is 1/16 of the opening size.  Larger numbers mean less light, small numbers mean you are adding light.
