Lens and Sensor Cleaning
My wife has spots in all her pictures

 7:27 pm on Sep 4, 2008 (gmt 0)

Rather than hijack one of the existing threads-I thought I'd start another. Do any of you professional photographers have any tips for lens and sensor cleaning?

My wife has a Canon 20D and lately all of her pictures have the same spots in them. I think her lenses and sensor are dirty-but I'm afraid of making the problem worse with my shop vac. Any suggestions?

Not sure about cleaning the sensor (or how it got dirty), but for the lens, breathe on the lens surface to fog it up and then gently wipe it with a clean microfiber cloth.

You can get the cloth at most supermarkets or hardware stores.

Don't ever use a paper towel or ordinary toilet paper, they can grind dust in to the lens and they leave residue.

I'm probably using the wrong terminology-I'm referring to the mirror you see inside the camera body when the lens is removed. I think that part (or something else internal) is dirty, as there are similar spot patterns even after switching lenses.

If you are referring to the mirror, don't touch it... ever. Try using an air canister GENTLY. If that does not work, you should have it professionally cleaned/repaired.

If you touch the mirror, even slightly, you can move it out of its default position and this would make all of your images even worse then they are now.

That sounds serious. She bought some sort of cleaning kit for it some months ago and tried to clean the mirror... Maybe that's the problem.

good luck
