Slide it to the left and see what effect it has on your pic. Now when you are happy with it click on preview and it will give you a preview of your BACKGROUND if your happy with the way the background looks then (CLICK APPLY)go to file and Click on save as to your folder that you made or put it to where you can get to it whenever your ready to use it.
