The inner workings of digital SLR rely on image sensors. These sensors capture the image by electrostatic charges, which the dust, along with many particles to attract the same sensors. Certain areas, such as dirt fields, beaches, parks, or have more dust than others.
We must save our SLR from dust, if we are to achieve consistent results, is not an easy win this fight because of dust several ways to get into our bodies down cameraand hold the sensor. This happens especially when the lens is replaced, or it happens when the sensors get charged - drawing in the dust. Probably the easiest way to avoid the dust by the lens in a clean place without dust - but it makes sense, not the camera lens in a windy, dusty or sandy location.
It is much better if they closed in a room before to change for a shooting. It can be noticed when the camera is easily affected by dust. Shoot onePicture of a clear blue sky or a smooth white surface, well lit. Shoot without a flash, like f/16 or f/22, if the camera has a zoom lens to shoot test shots at a wide angle. When the camera zooms in, the dust appears as a soft spot blob instead of a place.
When the record pictures, try to keep the camera at a downward angle to avoid when changing the lens on the ingress of dust from above. Basically, the mirror in the SLR offers solid protection for the sensor of dust.Accumulate the mirror / sensor chamber, the dust can, should therefore be kept clean to prevent dust from their path to the sensor. In case it is decided to change the lens on the field to try to find a sheltered spot. Try to reduce the time of the camera kept open, by the glass cover ready for a swap.
Giotto Rocket Air Blower is a good product to keep for the removal of dust from the camera. Reviews have said that it is easy to carry, but bulky. Apart from that it is a goodProduct. It cleans effectively only with a puff or two, and it is better, at home or in the studio clean. Never clean the inside of the camera with compressed air can be stored in an aerosol.
The propellant in aerosol sprays can sometimes be a liquid that evaporates quickly without residue behind on the surface of the sensor as a result of a malfunction of the sensor. The blowers are working a lot better. The blower is useful, if possible, within reach. It helps eliminateMassive dust in a simple way to help a couple of photographers who use editing software to remove the particles from the images to keep their cameras clean.
Avoid Another way to protect against dust, which may in emergencies you shoot with wide openings. This reduces the camera depth and negative impact that dust can have on an image. However, this should not be a practice, as dust if it is allowed to accumulate on the sensor surface, the lowersensitivity.
