To take photos underwater is extremely exhausting. I had to dive and position myself before my model and I went up, after my model, to get a deep breath of air. I guess I drunk unintentionally almost 3 litres of water out of the pool by struggling to get up and down and up and down. It was also very hard for Maria, but she coped with it quite well. At the end none of us was able to do anything anymore that day. We had reached our limit and there was only one option: Hopping into bed and sleeping like a baby! - The concept was just: "weightless"
