I processed this as basic editing then was very happy to realize it was advanced editing because then I could clone out some spots in the water. It's simply a branch that I threw into a calm pond, waited for the ripples to go away, then took a few pictures before the ducks made more ripples. It was also raining so there might be a few raindrop ripples in the water.
There was a guy that did this a lot. I forget his name but he acheived some level of fame. PopPhoto did a "fix" on this as well. I have been trying my hand at it but I gotta say, I like yours. The water does it.
