Grid in Viewfinder

A grid is something like a #, this feature is available in almost every digicams nowadays. Some professional photographers might call it rules of 1/3. To the hell with those tech terms, I'm just a normal user.

So how do you use a grid? The picture below will show you much info. This is from the N95 camera.Try focusing your objects at the circled points next time, you might get unexpected results. Unless you want your objects to be always at the center of your photographs.

P/S: I know the circles are uneven, please bear with it.
