How to set my nikon d3000 to where i can take my photos through the lcd screen?

I love my camera but sometimes i want to take photos through the lcd screen. Is there any way to set my camera to where i can take photos by looking through the lcd instead of just looking at my photos through the lcd?

The d3000 doesn't have live view (a drawback/advantage however you view it). The step up from the d3000 (the d90) does have live view which is activated through a button on the back.

Live view is simply not that helpful with fixed LCD cameras like the D3000 because they make focusing harder and don't show the full detail of the resulting photo and can't come close to matching the detail of the viewfinder as that is a direct sight to the subject.

Learning to use the viewfinder well is an essential of photography and relying on the LCD screen is just going to lead to trouble.
