Panning a camera is to move it in the direction of a moving object so that the background is a streaky blur while the moving object is in sharp focus :
To get a good streaky background use these tricks :
1. Set the Mode Dial to Shutter Priority. Choose a shutter speed depending on the speed of the moving object or start from a slow shutter speed and experiment.
2. Put the lens on manual focus and focus on the moving object by turning the focusing ring.
3. In Quick Settings choose the Continuous Shooting Drive Mode.
4. Click the shutter and follow the moving object with the camera so that it is always in the screen. Stand with feet slightly apart and swivel from the waist.
