Kling 2.5 Turbo (pro)
A vast prehistoric cave illuminated only by a single circular shaft of light high in the ceiling. Dozens of primitive tribespeople move through darkness, barely visible. A young man, 30 years old, intelligent eyes, rugged appearance, sits beneath the light experimenting with animal fat, fibers, and carved stone containers. Dust floats through the beam like stars. The cave walls disappear into blackness. Atmospheric darkness, realistic prehistoric setting, cinematic lighting, slow dolly camera movement, ultra-detailed textures, epic scale, documentary realism, volumetric light, immersive mood.
