In the center of the picture is a large mirror, which reflects the scenery of the park, including trees, grass and pedestrians. There are several people in front of the mirror. Some of them are taking photos and some of them are talking. This composition method creates a combination of virtual and real through the mirror, which increases the sense of hierarchy and interest of the picture. The brick wall as the background gives people a sense of stability and solidity, while the view of the park in the mirror brings a natural and open atmosphere. On the whole, this composition cleverly uses the mirror to expand the space, so that the picture has both realistic scenes and reflected illusory scenes, forming a unique visual effect.
