I was asked to shoot a soccer school for promotion. The idea was simple. Capture everybody individually in action and make a group picture. We were expecting cloudy weather for more dramatic result but instead got sunny/cloudy day with fast changing conditions. So we decided to hide behind a building that was blocking the sun and used it's shaddow to get more controlled environment. Time went by pretty quickly so the shaddow at the end of photoshoot was almost gone but at that time we already were finishing so it turned out to be the best choice after all.
