surfer riding a standing wave in a river

surfer riding a standing wave in a river. The surfer is a male, wearing dark shorts and no shirt. He is on a surfboard, in a crouched position, riding the wave. The water is turbulent and foamy, with strong currents. In the background, on the bank of the river, there are several people standing, some holding surfboards. The environment appears to be outdoors, with trees and some structures visible in the distance. The lighting suggests it is either early morning or late evening. Another person is visible in the water further up the river, appearing to be swimming or floating. The camera angle is from above and to the side of the river, looking down at the surfer. The footage is continuous and appears to be a single shot or edited to appear as such.
