Learn Photography: 10 Tips For Taking Pictures Like A Professional
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.
Understand the range of your flash
If you are taking a picture out of the range of the flash, it will not lighten the picture properly and your picture will be dark. If you are too close, the subject could be whitewashed. A good rule of thumb is to be about 10 feet from your subject if you cannot find out the range of your flash in the manual.
