Nano Banana Negative Prompts Guide

Improve a product image draft while preserving product truth.

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.

It separates product facts from background cleanup and keeps misleading commercial claims out of the draft.

Change a setting without damaging the authorized subject.

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.

The prompt names what is allowed to change and what must stay stable, which makes the edit easier to review.

Create a character direction without copying a real person or protected 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.

It keeps the character useful for ideation while moving the prompt away from identity and IP risks.

Draft a promotional poster with safer claims and better layout control.

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.

It treats the negative prompt as layout and claim control instead of a request for official-looking assets.

Generate variants from an authorized reference without promising perfect matching.

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.

It uses reference anchors while making clear that consistency is reviewable, not guaranteed.

Guide detail cleanup for a jewelry image without fake proof claims.

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.

It focuses on visible product quality while blocking authenticity and material claims the image cannot prove.

Explore original logo directions without creating a trademark-ready clone.

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.

It supports ideation while making trademark review and legal clearance a separate human step.

Keep a creator thumbnail readable without exaggerating identity or proof.

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.

It aims the negative prompt at clarity, layout, and trust rather than sensational imitation.

Generate an original scene direction while avoiding brand or style-copy overclaim.

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.

It keeps the prompt broad enough for creative direction without leaning on protected style-copy claims.

Polish a food, drink, or package image without adding unsupported details.

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.

It guards against visual polish that changes product truth or creates regulated-sounding claims.

Improve an authorized image while avoiding deceptive person or body changes.

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.

It frames the task as technical cleanup, not identity manipulation or deceptive before-after proof.

Repair one recurring visual failure after an initial generation.

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.

It keeps troubleshooting narrow, which makes it easier to learn whether the negative prompt helped.
