An ultra- realistic, high- definition 8K image of a man holding a camera in his hand, taking a selfie while running at full speed, with a massive black bear chasing him from behind. The man is mid- stride, his body angled slightly forward, clearly pushing himself to his physical limits to escape. His facial expression is a mix of pure terror and adrenaline, with wide- open eyes and his mouth in a scream or shout. Sweat drips down his face, and his clothes are slightly disheveled from the intense movement. The black bear behind him is enormous and menacing, with sharp teeth bared and powerful muscles visible beneath its thick, glossy fur. Its claws dig into the dirt as it charges aggressively. The proximity between the man and the bear creates an edge- of- your- seat tension. The scene is shot in a dramatic GoPro- style wide- angle perspective, emphasizing the man in the foreground while showing the bear looming in the background. Motion blur enhances the feeling of high- speed movement, with the dense forest around them slightly out of focus due to the action. The forest features tall trees with sunlight filtering through the canopy, casting dappled light and shadows. The ground is covered with leaves, dirt, and roots, creating a dynamic, rugged environment. Every detail, from the man's sweat to the bear's fur and the forest's textures, is rendered with photorealistic clarity. The overall atmosphere is intense, cinematic, and adrenaline- fueled. creativity
