Capturing the Movement of Marathon Runners with Longer Exposures

Runners in broad daylight aren't often captured as motion blurs, but that's exactly how Flickr user Justin (just big feet) shot the London Marathon. Just stick a neutral density filter or two onto your lens to restrict the amount of light entering your camera, allowing you to shoot at slower shutter speeds.

Microsoft Researchers Use Motion Sensors to Combat Camera Blur

At SIGGRAPH 2010 in Los Angeles last month, Microsoft researchers showed off some new technology that improves existing digital blur reduction techniques by outfitting a camera with motion detecting sensors.

The team created an off-the-shelf hardware attachment consisting of a three-axis accelerometer, three gyroscopes, and a Bluetooth radio, attaching the setup to a Canon 1Ds Mark III camera. The researchers then created a software algorithm to use the motion information captured during the exposure to do "dense, per-pixel spatially-varying image deblurring".
