09/19/06: Creative Motion Blur - In Camera!

Ever wonder how a shot like this is created?

Think it's some fancy Photoshop work? Think again!

The image was created with the camera on a tripod using about a 1 to 1 1/2 second exposure (camera set to shutter priority mode) and a 28-135mm lens. As soon as the shutter opens, I gently zoom the lens from it's widest angle (28mm) to telephoto (135mm) and I time it such that I reach 135mm on the zoom at approximately the time the shutter closes (basically it's a 1 to 1 1/2 second zoom). This takes a little practice to minimize camera shake and get the timing right...but after you do it a few times you'll get the hang, and you don't have to be precise on the timing.

You can even do something like this while hand holding the camera. Just use a shutter speed of about 1/10 to 1/15 and don't expect the center part to be tack sharp. It works okay with moving objects...as long as you are tracking the object such that the motion blur on the subject is minimized but everything else is blurred. Here's an example...
