What Is Anti-Shake and how Is it Used In Photography?

In photography an anti-shake system compensates for unwanted movement of the camera which would otherwise blur a photograph whilst shooting, for example hand holding a camera whilst shooting in low light conditions. There are two main types of anti-shake system; Lens based anti-shake uses a moving optical element to counteract shaking. Camera based anti-shake uses a mechanism which allows the image sensor to move to compensate for unwanted movement. Anti-shake systems are also extremely popular with videographers who’s cameras do double duty as both a stills and video capture system. When used in Video mode anti-shake systems help reduce the amount of visual ‘judder’ apparent in a video making it easier for the viewers eye to track the subject within a scene.
