Maintenance on your Sony Alpha A99V

No matter how careful you are with your camera, you will eventually get dust on your sensor. Sony can only approve one method of cleaning performed by customers, which is using a manual, rubber air blower (rocket blower), other methods carries a risk of damaging your camera.

Detecting Dust

The easists way to find your dust spots is taking a photo of a uniform surface or the sky, and bringing this photo into camera raw. This example is from a sunny day, with plenty uniform surfaces, and it illustrates how to see the dust dead easy in camera raw.

I tried cheap gel sticks once with my A37 and have never used them again! Wet wipes with swabs allways does the trick for me when the blower does not remove all of thye dust 🙂
