Quick camera-light tutorial

So I decided to put this up for you. As you can see, where you put your focus and where you actually take the picture greatly changes the outcome of the photo. This is taken with a compact camera, and with a system camera you probably just change your ISO to make the same effect. But not everyone need or can afford a system camera, so this is an easy way to change your pictures without that.

And I feel I should clarify:
Blue circle is where I put the little "focus-box" on the camera screen when I took the picture.
And you can enlarge the picture by clicking at it.
