Avoiding Digital Camera Shakes

If ever you have seen a picture that is blurred, it is most probably because the camera was shaken while the picture was taken. With traditional photographic film cameras, it was evident only after the negatives and positives were made. However, with digital camera, the captured image can be seen immediately on the LCD screen, and if the image has shaken, then it can be discarded for a new shot.

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

The shutter speed also plays an important role in blurring the picture. The shutter speed is the amount of time the shutter remains 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 the lens aperture and the shutter speed. A slow shutter speed needs a small aperture (large F-stop number) to avoid over exposure. With a slow shutter speed below 1/60th of a second, over exposure is adequately controlled, but the digital camera is likely to vibrate more, giving a shaky picture.

A tripod is extremely useful to eliminate digital camera shakes. It is generally used by sports photographers who use long telephoto lens, as it helps in close-ups, landscape and panning shots, for timed exposures, for shooting at slow shutter speeds, and for taking photographs in low or dim light conditions. Shooting a fast moving subject, like athletes, or wildlife, tests the photographer`s skill and the equipment. In such cases, camera shakes are most likely to happen, and thus a monopod or a tripod is always used. Digital cameras mounted on tripods always tend to eliminate camera shakes and give sharp results.
