Many of us are getting into the dSLR club these days. Especially as prices drop and brighter lenses reach consumer prices, we're able to get our hands on some pretty fancy tech. So, as an amateur photographer, you should at least know how to properly clean that fancy new lens, right?
One nice thing about this tutorial is that it's pretty simple. All you need are a few items you probably already have laying around; the technique is where it's really at (If 8 minutes seems too long for you, we have a step-by-step guide over here).
The same blowing technique shown in the video works on the sensor if you're suffering from dust particles ruining your images. Just be careful not to touch it. It's the brains of the dSLR.
But hey, if you're still fearful that the air blow will be sitting around doing nothing when not in use, you can count on using it as an effective monitor duster. See? A little bit of creativity can go a long way.
