There are many things you can try simply by using your camera: Switch to a different white balance than the one you are actually shooting under. Trip the shutter while zooming in or out. Try your hand at panning - my Canon does it perfectly in auto mode, but my Sony can't do it at all in any mode unless I preset a lot of settings before hand. Enjoy your photography.
