There are different ways to greet the sun when it rises in the morning. Some prefer it with a shot of rum, others by doing yoga. I prefer the shot, with my camera. The important thing is to arrive at an interesting, lonely spot, way before the sun even thinks about rising above the horizon.
The horizon is easy to find, out in the open. If you have a large body of water at your disposal it will be even easier. By the way, you don’t have an excuse for a crooked horizon this time.
