Microsoft Research Blink app for Windows Phone 8, lets user capture a burst of images by just aiming the camera at your intended object, once the Blink app open, it starts taking images before or after snapping a picture, either by clicking on the sutter or by tapping on the screen.
The app continues to capture pictures after you've taken your shot. You then get a series of images that you can check out via a strip on the bottom of the screen. When you see the image that you think is the best one of that subject, you can select it and it becomes part of your official Camera Roll.
"It's no problem if you press the shutter a few seconds too early or too late. With BLINK, a simple finger swipe lets you find the perfect shot. Advanced image stabilization technology from Microsoft Research removes camera shake and lets you focus on the important parts of the scene," Microsoft stated.
