There was a talk and presentation at my Photography Club a couple of months ago about composition and playing with your camera to achieve different artistic effects ‘in camera’ (ie not in software post processing)
One of them was to set your shutterspeed a bit slower than usual and zoom in on an object and then as you press the button ZOOM out really fast. It was a simple and very effective technique and I *remembered* it today while I was out taking some photos of roses.
And this is what it looks like! (click on the picture for the bigger version which shows more detail)
