Dust on DSLR Sensor

The CCD sensor is the "heart" of a digital camera and should be held as far as possible be protected from dirt and dust.

After all, this is a particularly sensitive, electronic component, on the sensitive photodiodes are mounted. Dust particles and other contaminants, which settle on the sensor surface can, in extreme cases, to photos and videos appear as black grains and tarnish the image in the truest sense of the word. Many photographers rightly wonder how the dust can actually penetrate to the sensor surface - after all, is not to disclose, but is hidden by the mirror and the shutter of the camera.

In principle be running an "intrusion" into several stages: First, individual dust particles caught in a change of objective housing interior. You will then gradually with each release in direction sensor surface, because when you shoot the mirror and shutter are moved by nature. So the dirt paves depending on the use intensity and frequency of the sensor and on the resulting picture taken. The whole thing's on the way, even in apparently dust-free environments and has initially do with the "cleanliness" of your home or work space back: Often you can not see the dust particles with the naked eye - first in the group sit down to a significant "troublemaker" together .

Another approach to sensor-dust pollution is on housing covers and the actual lenses. Mounted, for example, a long time on the shelf mounted lens on an SLR camera, can you lift the lid down fine dust particles raining down on the front of lens.

Manufacturers such as Canon and Nikon are trying such phenomena by automatic cleaning systems, multi-phase counter. Here, the sensor surface is cleaned thoroughly with including sound waves. Even if those cleaning concepts of modern digital cameras are becoming more sophisticated, can one really "dust proof" camera yet to come - not least because they swear by professional photographers is still on the good old "hand wash".
