I am about to enter a brave new world in digital photography. Since upgrading to a full frame sensor camera a few weeks ago, I have discovered a new feature of digital photography. Dust.

I had the old D60 cleaned once in 4 years, but the new 5D has picked up significant dust already. So I have purchased an expensive cleaning brush that is supposed to do the job. But two trips to the camera service centre will cost more. It is time to learn how to clean my own camera.

Update:

It worked!
