Learn Photography: 10 Tips For Taking Pictures Like A Professional
Move closer to your subject
A good rule of thumb is to consider the size of your subject and step closer to them if they are smaller than a car. You want to fill the picture with your subject and by moving closer or zooming in on them, you can capture unique things about them.
Make sure you don't get any closer than what your camera can truly capture; about three feet. Otherwise, your pictures could turn out fuzzy.
Lock the focus of your camera on your subject and not on something else
This will require you turning off the auto-focus feature on your camera. Whenever you take a picture of someone or something that is not in the center of the photo, locking the focus will force the camera to blur the background and not the subject.
