You often find that the picture you take is blurring or become bad? This thing happens when you took out the picture, the camera or your hand shake. To eliminate the blur we can do several things:
1. Use a faster shutter speed and/or a shorter lens.
The main way to eliminate shake is using faster shutter speed. Either by opening the aperture wider or introducing more light by using a flash gun for instance. The main rule for a sharp picture, free from the effects of camera shake, is to use a shutter speed which is at least as fast as 1 divided by the focal length of the lens. So if you are using your zoom set at 100mm you should use a shutter speed of at least 1/100 of a second. If you are using a 50mm lens you will get a sharp picture at 1/50th of a second. The narrower the angle what you want to take, then the more the shake is magnified.
2. Use a tripod with or without a remote release.
Putting the camera on a tripod is the best way to keep it still and not shaking, especially when you want to get some movement blur from the subject like in the event of bike riding or landscape like waterfall. Even better is to get a remote release for the camera so you don’t have to touch it at all.
3. Brace ourselves as best we can against a wall or other object to minimize movement.
If you didn’t bring your tripod with you and you still want to take pictures in the dark, you can stretch the rule of thumb by a few stops by bracing yourself and/or the camera against a tree or wall or lamppost. Don not forgets to control your breathing.
