The photo is taken from the back of a ferry, facing the stern. The ferry is travelling through the Aegean Sea, leaving a white wake in its path. Three seagulls are flying in the air, with one flying in the foreground, and two in the distance. There is a blue sky with a few white clouds in the background. In the distance, there is a hazy outline of an island. The coordinates 40.857, 24.681 locate the image near Kavala, Greece. The scene is calm and peaceful. The ferry is moving at a moderate speed, the sea is calm and there is no wind. The seagulls are flying effortlessly. The photo appears to be taken on a sunny day.
