用光影，为产品揭幕

A 6-second studio product reveal of [product and its visible materials]. Begin with a close detail of its surface, then slowly dolly backward to reveal the complete silhouette on a simple pedestal. A broad softbox moves a gentle highlight across the material; the object remains physically still. Background: [color]. Preserve the product geometry, proportions, and any supplied reference details throughout the shot. Realistic lighting, smooth camera motion, no cuts, invented logos, feature claims, or text. 16:9.
