This pair of swans were fouraring in calm water at twilight. in order not to disturb these, I placed my waterproof camera on a small pocket tripod (15 cm height) in the water with the lens just above water surface. Then I turned on the 10 sec self timer and moved away slowly. At the shooting point, I had my back facing the swans, but the bonus turned out to be the swan couple behaving not alert!

This photo could not be hand held, due to the fairly long exposure time.
