At night, a person stands in a park holding a smartphone to record a video of the surrounding trees and the lit Saint Isaac's Cathedral in the background. The park is illuminated with bright green lights highlighting the trees. The person's left arm is visible, clad in a dark leather jacket. The phone's screen reflects the scene in front of it, including a tree trunk with a thin green light band. The Cathedral is visible between the trees, illuminated in a warm color. The camera moves slightly, providing a dynamic view of the scene.
