Use the sensor swab
(with one or two drops of sensor cleaning fluid) to gently wipe away the more stubborn dirt
particles. Check the directions that came with the swab. You can see a typical sensor swab in
Figure 2-8.
FIGURE 2-8 Cleaning your camera sensor might seem intimidating, but it??™s easy to do if you
follow the directions, use common sense, and work gently (so you don??™t scratch
the sensor).
38 How to Do Everything: Digital Camera
That??™s all there is to it. Follow your camera manual??™s instructions to disengage the mirror
lockup, and then take a couple of new test shots. Inspect them for signs of dust and, if necessary,
clean the sensor again. As long as you are careful about not leaving your sensor exposed to the
environment for long while you change lenses, you should only need to clean your sensor once
every six months or more.
Some Digital SLRs now come with a ???self cleaning sensor.??? These cameras vibrate the
sensor to shake dust loose. That??™s a great feature, but it doesn??™t completely eliminate the
need to clean the sensor by hand occasionally, since this automatic cleaning cycle only
shakes the dust around inside the chamber??”and the electrostatic nature of the sensor
will eventually just attract the dust all over again.
