Tips from Tim Grey on How to Prevent Dust on your Digital Sensor
The issue of dust with digital SLRs is particularly challenging because once the dust gets stuck to the sensor it may appear in every single photograph you capture until the dust is removed. Fortunately, a few simple practices will help you greatly reduce the problem of dust. The first, of course, is to try to prevent dust from getting into the camera in the first place. This is really a matter of minimizing the dust, because dust is everywhere and difficult to avoid. Make every effort to change lenses in whatever environment available to you at the time has the least amount of dust or other airborne contaminants. This may be in your vehicle, in a tent, within a camera bag, or some other structure. When all else fails, at least turn your back to the wind to try to minimize the amount of dust that is able to enter the camera. When you do change lenses, it is obviously beneficial to do so as quickly as possible to minimize the exposure to dust. Also, it is best to turn off the camera during the process of changing lenses so the sensor doesn't have a charge. This will help prevent the sensor from acting like a magnet for dust as you're changing lenses. I also recommend using a blower bulb to blow off any dust that may be on the sensor whenever you change lenses. The reason I recommend this is that dust that initially lands on the sensor isn't likely to stick, and can be blown away quite easily. The real problem occurs when dust is allowed to sit on the sensor for a period of time. When you mix dust and humidity, the result is a "crust" that will stick quite well to the imaging sensor, and can be very difficult to clean. This is the same type of crust you'll find on the internal moving components of those old-fashioned computer mice with a ball and rollers inside. If you do end up with dust on the sensor, there are many options for cleaning them. If you are willing to clean the camera yourself, be sure to check out http://www.cleaningdigitalcameras.com/ for some great information on exactly how to do just that.
