Panning is a very cool technique that allow you to capture amazing result on the moving object. This is a technique that you pan your camera along in time with the moving subject and end up getting a relatively sharp subject but a blurred background.
Have a look on below photograph taken by Steve Seow. Cool right?

How do you do it?
- The basic idea to do this is using a slower shuttle speed and pan your camera along with the moving subject. When in a slower shuttle speed, your panning action will created a blur effect on the background but the moving object remain sharp.
- Select a slower shuttle speed, start with 1/30 and try to test around. The environment light need to be consider as well, at the end, you might end up with 1/50 like picture above. Just make sure the shoot will not overexposure(too bright).
- Focus the moving subject. Pre focus the subject upon on the spot that you going to release the shuttle.
- Once you release the shuttle, do it gently to reduce the camera shake. Continue to pan on the subject although you heard the shuttle closed.
- On above photograph, steady hold your camera, focus on the motorcycle, release the shuttle and move your camera from right to left on a straight line.
To get a nice panning image, it depend on practice and some luck, but do consider how you choose the background, the blurred background will be another key point that is your image look amazing or not. For example, in Steve's photograph, the yellow and pink line on the bottom were just nice to explained how important to select a proper background, just imagine, if the lines no longer there, will the photo missing something :)? I am sure the answer is yes.
