Introduction:
One of the things that "pops" your subject off of the photograph is when the background is out of focus of blurred. It helps to show that you have a better understanding of how to use the features of your camera. It also helps to hide unwanted objects in the background from detracting from the point of focus of the image.

- Background Focus with various F-Stops
How to Blur the Background:
1. Turn your camera from "P" mode for professional (joke), to Av or Aperture Priority.
2. Select the lowest F-Stop that your lens has.
3. If you have a normal quality kit lens, this may only be F 5.6 or so. You don't have to have F 1.2 lenses
4. If you don't have a low F-Stop lens, consider purchasing the Canon 50 mm, F 1.4 or F1.8 lens (the low cost one). You will then have a tool that can help you take great photos.
5. Rack out your lens as far as possible. This may mean moving farther back, but you will compress your background.
DOF - Use this Reminder When Choosing your F-Stop (depth of field)
Caution: When shooting groups of people at various depths it is more important to get the subjects in focus than to blur the background.
Masters-Tip: Use low F-Stops to blur the background when shooting 1 or 2 subjects
Masters-Tip: Rack out the telephoto to compress the background
Masters-Tip: The 50 mm lens will be your best low cost low F-Stop lens
Remember: Masters-Tip: Get the shot (in focus and with proper exposure) Period! You can always fix it in Photoshop.
Summary:
We always teach, Get it Right in the Camera as much as possible. When using low F-Stops, DOF plays a big role. You must be able to still your body by pressing your elbows against your chest and breathing slowly. We have many tools to fix it later, like DXO and the bokeh slider. In PS, you can blur the background in multiple ways.
