Creative Light Motion: A narrow beam of warm light slowly sweeps across the scene from one side to the other. As the light passes over the bottle, the glass surface produces strong refraction and layered highlights. Multiple soft light bands appear and move gradually, creating a sense of depth and premium texture. The internal liquid reacts subtly to the light, with gentle brightness variations and soft glow changes, without any visible movement of the liquid. The edges of the bottle catch sharp rim light, then fade smoothly. The shadow beneath the bottle shifts slightly in softness and intensity, responding to the moving light. Atmosphere Enhancement: The background gradient becomes more saturated when illuminated, then softly returns to neutral. A faint halo glow briefly forms around the bottle during peak light, then disappears.
