Everything a Blur?

A camera works more or less like our eyes. Light reflected off surfaces passes through the lens of our eye and falls on the retina. These impulses are carried by the optic nerve to our brain, which interprets the image, and we can see. A camera records light that bounces off the subject. The various hues and shades of reflected light pass through the camera lens and fall on a film or a digital sensor in a particular pattern, producing a sharp image. This image is recorded on film or a memory chip, either for printing or viewing on a computer screen.

As a photographer, you are no less than a captain maneuvering his ship. You’ve got to be alert and steer your ship in the right direction, avoiding danger and reaching your destination safely. In the same way a photographer needs to know how, how much, how long and how fast to guide the available light through the lens of his camera, in order to produce a perfect picture. Therefore you must get acquainted with a few technical details like shutter speed, aperture size and film speed.

Were you ever disappointed because your pictures turned out to be blurry? And that too, the ones you were looking forward to? There could be various reasons for blurry pictures.

  • One of the most common causes is camera shake. While taking a picture, if your camera experiences even a slight jerk when the shutter is open, the pictures may turn out blurry. Camera shake can be avoided by holding your camera firmly with your elbows against your sides. Alternatively, you could increase your shutter speed, thus reducing the length of time your shutter remains open. While clicking, don’t hit the shutter-release button but gentle click on it. Keeping the button half-pressed before clicking can also help. If your hands are shaky, you can fix your camera on a tripod.

  • It is possible that your subject suddenly moved, causing the blur. If you are photographing a naughty child, again, increasing your shutter speed may help. If you are using a camera with preset modes, switching to action mode may help capture shaky objects. Shutter lag may make an impatient subject move.

  • Although most people blame blurry image on focus, very rarely will this be true. Probably your subject is too far or too close to the camera. Sometimes the point where your camera focuses may vary from your point of focus. Experts use the ‘rule of thirds’ to cure this problem.

  • If you are taking a picture of a moving object, you need some experience. Apart from increasing the shutter speed you must also use a film that has a higher ISO value.

  • If you are using a zoom lens, wait for your lens to move completely before clicking.

  • Or maybe it’s something as simple as a dirty lens. Use a soft cloth and a lens cleaner solution to gently wipe the lens.

A little knowledge and a little precaution will help you get the best results.
