Nano Banana Negative Prompts 指南

在保留产品事实的前提下改善产品图草稿。

Create a clean ecommerce product photo for [owned or authorized product]. Keep the product shape, label area, main material, color, and front-facing crop. Avoid cluttered backgrounds, warped label text, extra accessories, copied third-party marks, fake marketplace badges, altered features, and unsupported claims. Review the result for product accuracy before publishing.

它把产品事实和背景清理分开，同时避免误导性商业声明进入草稿。

更换场景，同时不破坏授权主体。

Use my authorized reference image as the source. Keep the main subject, camera angle, edge detail, natural shadow direction, and crop. Replace the background with [new setting]. Avoid changing the subject identity, adding unrelated people, creating copied logos, inventing proof badges, or making the edit look deceptive.

它说清哪些可以变、哪些必须稳定，方便你复核编辑结果。

创建角色方向，但不复制真实人物或受保护 IP。

Create an original [role or mascot] character concept with [silhouette], [outfit direction], [color palette], and [pose]. Keep the design fictional and distinct. Avoid real-person likeness, protected character cues, copied franchise elements, deceptive identity use, distorted proportions, and unreadable accessories.

它保留角色创意价值，同时避开身份和 IP 风险。

起草宣传海报，同时保持声明和版式更安全。

Create an original poster concept for [event or campaign type]. Keep a clear headline area, central subject, readable spacing, and balanced margins. Avoid fake sponsors, official-event claims, protected logo copy, misleading award badges, unreadable small text, crowded composition, and cropped faces.

它把 negative prompt 用在版式和声明控制上，而不是生成像官方物料的资产。

基于授权参考图生成变体，但不承诺完美匹配。

Use the reference as visual guidance for [subject or product]. Keep the approved colors, broad silhouette, material direction, and camera distance. Avoid identity drift, extra limbs, altered product facts, protected trade dress, copied marks, and claims of exact match or official approval. Review the output as a draft variant.

它使用参考锚点，同时明确一致性需要复核，而不是保证。

指导珠宝图细节清理，但不制造虚假证明。

Create a jewelry product image for [owned or fictional item]. Keep item type, metal tone, stone color, scale, clasp or setting details, and soft reflection. Avoid fake certificates, unverified purity or carat claims, counterfeit styling, protected trade dress, extra stones, warped prongs, and unrealistic shadow.

它聚焦可见的产品质量，同时阻止图片承担无法证明的真伪或材质声明。

探索原创 logo 方向，但不生成商标级复制品。

Create an original logo concept direction for [fictional or owned project]. Keep the mark simple, scalable, and distinct. Avoid copied protected marks, official-brand styling, fake certification seals, confusing similarity, tiny unreadable text, and claims that the output is legally cleared.

它支持创意探索，同时把商标审查和法律清理保留为人工步骤。

让创作者缩略图更易读，同时不过度夸张身份或证明。

Create a thumbnail concept for [topic]. Keep one clear focal subject, high-contrast background, readable empty text area, and energetic but honest mood. Avoid copied channel branding, misleading before-after proof, fake platform badges, distorted faces, extra hands, cluttered props, and unreadable text.

它把 negative prompt 指向清晰度、版式和信任，而不是猎奇式模仿。

生成原创空间方向，避免品牌或风格复制过度声明。

Create an original [room, studio, or set] concept with [materials], [lighting], and [camera angle]. Keep the layout practical and visually calm. Avoid copied signature interiors, protected brand elements, impossible furniture scale, floating objects, harsh artifacts, and claims that the design follows a specific protected creator style.

它保留创意方向，同时不依赖受保护风格复制声明。

打磨食品、饮品或包装图，但不添加不支持的细节。

Create a clean [food, drink, or package] image for [owned or fictional product]. Keep verified ingredients, package shape, label area, and serving context. Avoid invented health claims, fake ratings, copied marks, extra ingredients not provided, unnatural shine, warped packaging, and misleading serving size.

它避免视觉美化改变产品事实或制造监管性质的声明。

改善授权图片，同时避免欺骗性人物或身体变化。

Edit the authorized image to improve [lighting, background, crop, or color balance]. Keep the person or subject recognizable as provided and preserve natural proportions. Avoid identity changes, body-shape manipulation, added people, copied branding, fake documentary proof, and unrealistic skin or edge artifacts.

它把任务限定为技术清理，而不是身份操纵或欺骗性前后对比证明。

在首次生成后修复一个反复出现的视觉失败点。

Regenerate the same [image task]. Keep the subject, composition, color palette, and intended use unchanged. Avoid the previous failure: [blurred edges, extra objects, warped text, wrong background, odd shadow, or distorted proportion]. Do not add new claims, logos, people, or product features. Compare only the fixed issue before changing anything else.

它让排错保持窄范围，更容易判断 negative prompt 是否真的起作用。
