    Post Digital SLR Maintenance

    Moving into DSLRs brings alot of new things to learn, including maintenance. If you haven't already, you will learn about dust specs on your sensor, which turn into dust specs on your images. I have a couple of tools & products that I use to clean the sensors, which are relatively inexpensive, especially compared to sending your camera in to have it cleaned. To check your sensor for dust, do the following:

    set camera to manual focus
    point camera to the sky (try to avoid differences; clouds, etc)
    [you can also shoot a light colored solid background]
    set aperature to f22 (and everything else for correct exposure)
    make image
    *You can also step up & down to see just where in the aperature range the dust becomes a nuisance; usually by f8 for large specs or f16+ for smaller ones.

    Download the images. If you can live with the dust and don't mind removing it as part of your workflow, do nothing. If the specs are larger, clean the sensor if you're comfortable doing it.

    NOTE: Most camera manufacturers discourage the end user from doing anything to the sensor. Just be aware, if you break it, you own it. On the other hand, I have cleaned the sensors in my cameras too many times to count without incident (damn push/pull zoom).

    TIP: ALWAYS turn the power off and point the camera face down before changing your lens. This minimizes the cameras tendency to attract dust (image sensor is electrically charged with the power on). And naturally, avoid wind, dust, etc., while you're doing it.

    If this is all old news, I apologize. If it's not, go here for a sensor cleaning tutorial and products:

    Just want to add, I have had GREAT success in using Rocket Air...it's a filtered air blower that you can use to just blow loose dust off your sensor. It's kept my sensor very clean and I haven't even had to purchase Visible Dust yet (which I hear is highly recommended on other forums).

    Good point, Armin. thanks for the follow-up. I use the rocket blower myself. At first I was using a nasal aspirator (new!), but the rocket blower is way better.

    Peace,
