Digital camera shakes are common with new users. This is mainly because the new users have not understood that the trigger must be pressed twice, but followed two steps down. The first step locks the focus and exposure, while the second step takes the photo. This pressure has to be smooth button, otherwise the digital camera shakes and a blurred picture is the result.

Shutter speed also plays an important role in the blurring of the image. The shutter speed is the amount of time the shutter stays open to allow light to reach The digital camera sensor. It is measured in seconds or fractions of a second. An image is exposed by the combination of lens opening and shutter speed.

IS is an Anti-Shake and vibration reduction technology and is common in digital cameras with long telephoto zoom of 10X and 12X. With IS, sharp images can be obtained even if the camera shakes a bit, you use a slow shutter speed, shooting is done in dim light or a tripod not used. IS was originally developed for video cameras. Now available in interchangeable lenses, consumer and professional digital cameras that use optical image stabilization. Sports and photographers use a tripod and technology together to get the maximum sharpness of your pictures; However, many other photographers, to turn the function off when using a tripod.
