Yesterday I was searching the app store for photo apps and I stumbled across one called Photo Lake. Its the free version, which means no high res output. Luckily its still good enough to share online. I thought the effect was pretty cool and the app is very simple to use. Just set the water line and watch the ripples go.
I feel like it completely changed the second image. The freeway was in the foreground and, while it looked ok, I find the lake effect to be much more interesting, even if it is slightly unnatural.
