Play with the zoom effect
It's common use to adjust the
zoom before taking a picture, however there is particular technique that
requires the photographer to operate it while executing the shot. At
first select mode Shutter-priority and then set time around 1 second or longer.
The camera has to be set still so use a tripod or any solid surface
that can give you a clear view of the picture; press the button with one
hand while with the other action the zoom. You'll get an interesting
vortex effect .
