prop-prompt

Prop final prompt (single item on white background · standard product photography)

What is generated is a product shot on a white background (product shot):Using a standard product photography perspective, with only the prop itself in the frame, isolated on a pure white background,without mixing in any other elements—no other objects, no people, no scene environment, no hands holding it.

Three hard requirements:

1. Accurate proportions of each part of the object—no exaggeration, deformation, or stylized stretching; the relative size relationships of the prop must be realistic
2. Complete edges—the prop is fully in frame as a whole, with blank space around it; no part may be cropped by the frame edge
3. The background carries no narrative content—the pure white background is only a backing, with no sense of scene, no plot implication, and no decorative elements

Output structure (assemble a single coherent description in this order, with language following the conversation language instruction)

单品产品图，标准产品摄影视角，[道具名 + 材质/颜色/形状/大小 + 新旧程度与磨损细节]，
物品各部分比例准确，孤立放置在纯白背景上，居中完整入镜，边缘完整无裁切，
背景纯净不承载任何叙事内容，无其他物品、无人物、无场景，
柔和均匀的影棚光，轻淡阴影，高细节

Generation rules

• Use the prop name(name) and description(item appearance) as the core: physical details such as material, color, shape, size, degree of wear, and signs of wearspecified one by one, which is the source of the prop's recognizability
• Standard product photography perspective: slightly overhead 3/4 view (showing both top and side clearly, with the strongest sense of three-dimensionality); for flat props (paper, documents, photos), use a straight overhead flat lay
• The single item is presented centered and complete, with blank space around it, accurate proportions, complete edges, and do not crop the main body of the prop
• Soft, even studio lighting, light shadows, high detail
• Describe only the object itself; do not mention plot, characters, or use (neither the background nor the image carries narrative content)
• The output uses the target language specified by the conversation language instruction, without mixing in irrelevant words;do notuse "cinematic quality" type words (a prop image is a product image, not a still)

Prohibited items

• Hands holding it, people, other objects, or scene environment in frame
• Packaging, bases, display stands (unless they are part of the prop itself)
• Text, watermarks, signatures (text patterns printed on the prop itself may be retained and described)
• Environmental reflections, colored light
• Exaggerated perspective, deformation, distorted proportions, edge cropping
