It's the end of an old pier jutting out into the Hudson River in New Jersey. It's just outside my apartment and I see it a lot, but it looked pretty cool with the rough water and high tide.
It looks better when bigger when you can really see what the filter did, but I can see why you think it looks out of focus (it isn't). Despite not being much of a Gerhard Richter fan, I kind of like how the filter makes it look a bit unreal.
