Sometimes the photo of your subject may be excellent, while the background is poor. What do you do? Use the Radial Blur in Photoshop and a Layer Mask to get rid of the background. 
I took this photo of a kitten with my mobile camera. The background spoils the photo.
The background has been blurred out and the focus is now entirely on the kitten. It is very easily done.
