Product photography style. The main subject is an aged vintage traditional oil-paper umbrella. It is fully opened into a circle with a dark brown matte aged oil-paper canopy, featuring subtle wear marks and a weathered texture. The umbrella edge is naturally uneven from use. The radiating umbrella ribs are made of light brown natural bamboo, evenly distributed from the center and reinforced with thin brown threads wrapped at the center joint. The handle is a natural bamboo pole in light bamboo-yellow with distinct bamboo node textures, ending in a curved hook shape. It rests leaning on a dark gray matte ground, with a uniform gradient dark charcoal gray seamless backdrop. Mid-shot, 45-degree oblique camera angle. Soft side lighting casts a light shadow on the ground. The overall color palette features a calm combination of dark brown and gray-black, emphasizing the texture of aged oil paper and bamboo. Square aspect ratio.
