Sometimes you happen to wake up early naturally. And that's what happened that day.
I woke up early and saw the sun rising through the window. In a fraction of a second I decided to get my camera gear and cycle to the beach. The problem is that the beach is a 15mn ride from home and I thought I wouldn't have time to get there on time. Instead I cycled to the nearest park 5mn down the road and set up my tripod.
I was still half asleep but managed to get a few pictures.
I shot in RAW and exposed for the highlights which gave this dark look although it was sunrise.
