Tip #3, remove the filters.
Updated: Sep 8
I'm sure when you bought your camera the nice salesperson recommended a UV filter with it, and for good reason. Those little filters are great for taking the scratches so you don't damge your lens. I fully recommend leaving the filter on if you're out in the field or if you need it for your shot (as with a polarizer or neutral density filter). But when you're shooting in a studio and there's very little chance your camera is going to get bumped over, it's a good idea to remove the filter. Anything you put between your lens and the subject will slightly affect the overall sharpness of the image. Even if it's the highest quality filter ever made.
