Blurry photos are one of the most annoying outcomes in photography and there can be several causes. Blurry photos may be caused by one or more of the following, or a combination of these:
Camera shake: Tiny movement of the camera at the time you press the shutter button to take a photo.
Incorrect technique for holding your camera: Holding the camera at arm’s length to use the LCD screen. This creates a very unstable platform, especially if your camera is a big and heavy because you cannot support it correctly. Correct camera-holding technique for a camera with a viewfinder requires supporting the camera body/lens with your left hand and your left elbow tucked against your body. If the camera does not have a viewfinder, tuck your elbows against your body or utilise some other means of supporting your camera, such as placing it on/against a solid/rigid structure.
Unsuitable shooting mode: If you are shooting on Auto, a pre-set Scene mode or P, and to a letter degree Aperture Priority, the shutter speed your camera chooses may not be fast enough for you to hand-hold.
Shooting in low/poor/insufficient light: You need to use a higher ISO to give you a faster shutter speed or stabilise your camera on a tripod so you can use slower shutter speeds.
Shooting with a too slow shutter speed: To shoot with a slow shutter speed, you’ll have to either choose a higher ISO or a wider aperture to minimise camera shake. Shooting with slow shutter speeds almost always require use of a tripod.
Focal length is too long for your chosen shutter speed: For hand-held shooting, the lens focal length should be equal to the shutter speed. Eg. 18mm focal length = a shutter speed of 1/20 sec; 50mm focal length = a shutter speed of 1/50 sec; 300mm focal length = a shutter speed of 1/300 sec.
Next month, we’ll look at techniques to help you beat the shakes!
