Chris talks about a touchy subject in photography this week -- how to clean your camera. It's something he always gets questions on, and everyone has an opinion. On the outside, just use a damp cloth and wipe it down. But Chris just uses whatever he has. The lens is the one part of the camera he uses a microfiber cloth to wipe it with. Any soft cotton will actually work, but microfiber gives it plenty of TLC. Other tools include a lens brush and air blower. What about a lens pen? Chris says they work, but you can get the same results with the microfiber cloth.
The outside, though, is another issue altogether. First off, on the inside of the camera, a blower works just fine for the mirror box and most modern cameras have a cleaning sensor utility that sends a little hypersonic pulse to shake the dust off it. In general, that's all you really want to do. You can use a swab with a drop of alcohol on the sensor, but if you have to do that, it may be a better idea to have it professionally cleaned.
One myth - if you change the lens, you should turn the camera upside down to drop out the dust. That doesn't work because the dust is so light, it hovers in the air and the act of changing your lens will push air into the camera and thus, the dust inside it.
Don't forget our current assignment - Climate! Take a photo of, about, or otherwise concerning the concept of "Climate" and then post it to the Tech Guy Group on Flickr. Make sure to tag it with the word "Climate" as well! And if Chris likes it, it could end up on our next photo segment!
