A lot of newcomers to photography are so focused on their subject that they sometimes forget about the background of their photos. If you have a good eye for photography you’ll soon be able to recognize the type of backgrounds that can complement the photo’s subject. In addition, you’ll also realize when the background overwhelms it, which is something that you don’t want.
When taking photographs, you need to recognize if there is anything in the frame that could cause a problem in the finished shot. For example, you may be ready to take a photo of somebody and all of a sudden another person or a car pops out of nowhere and invades the frame. This could ruin the photo that you had planned on taking.
The same thing can also happen with background light changing in the frame as it can change in just a split second while you’re taking the shot.
