Hold your middle mouse button (usually the scroll wheel) or the PageUp key and move the mouse.
Press PageDown to reset the camera.

You can rotate your camera by holding your MiddleMouseButton (or PageUp) while dragging.
Edit: Sc00peD!
Thank you very much.
You can also hold Page Up and push the direction keys.
I completely forgot how to take a screencap of myself from the FRONT. I played other games and came back recently. Any help would be appriciated thanks.
