Before this challenge I wasn't a big fan of Intentional Camera Movement. But that is changing. I'm loving some of the artistic effects it can produce. It does take a lot of trial and error, multiple shots, post-editing etc., but it can be worth the effort. It is also a good technique to give up control if you're a control freak (very often you see the potential of your shot only on the screen of the computer during editing). I love this one as it looks very much like a painting.
Another take on the same boats over at leftovers.
I'm already working on the next challenge that will be completely different from this one.
