Camera Labs DSLR dust cleaning technique
Our technique for minimising and eliminating dust essentially follows the manufacturer's
advice from the previous page. Clearly the most vulnerable time is when the
lens is removed from the body, so beyond being careful about the environment
in which you change lenses, try and also apply the following.

switch the camera off to reduce the static charge on the sensor which could
Secondly, hold the camera facing down to minimise particles in the air from
entering - see photo left.
Third, use a body cap to prevent any dust from entering the camera, although
ensure it's clean and dust-free first.
And fourth, before you attach the new lens, ensure its rear surface is also
free from dust.
While the techniques
above will minimise the amount of dust entering the camera body, you'll still
almost certainly suffer from it at some point. The most effective technique
we've found for removing dust is simply blowing a few gushes of air into the
body using a blower brush, with the brush itself removed - see left.
Once again hold the camera body facing down and remove the lens. Then select
the option in your camera menu to clean the sensor. This simply flips open the
mirror and opens the shutter, revealing the sensor filter's surface; most cameras
demand you do this with a fully-charged battery or even a mains adapter to prevent
the mirror from flipping down unexpectedly.
Now use the
blower portion of a blower brush to blow a few gushes of air into the body.
It's advisable to position the blower just outside the camera body, again in
case the mirror were to flip shut unexpectedly - see photo left. We've found
three or four bursts of air are normally sufficient before switching the camera
off again to close the shutter and flip the mirror down.
If you already have dust on an image, the consolation is it is at least reasonably
easy to remove using standard cloning tools. The dust patches are most visible
on areas of blue sky or skin, which are generally easy to retouch.
