This is an Italian photographer named Pietro De Grandi who took a picture of Pragser Wildsee. This picture can be divided into three parts, first the rowers, then the blue lake, and finally the mountain scenery. It is divided into three layers. The photographer used the rule of thirds to complete the picture. After all, the protagonist of the photo is the rowers, so they occupy a more central position in the photo.
