25 Nano Banana Prompts for Editing, Product Photos, Text, and Characters
Copy practical Nano Banana prompts for photo editing, product scenes, character consistency, posters, and 4K finals—plus a workflow that saves credits.
The most reliable Nano Banana prompts define five things: what must stay unchanged, what should change, the visual style, the composition, and the output constraints.
You do not need a long prompt for every job. You need a brief that makes the editable and protected parts unambiguous.
Build a structured prompt with the free Nano Banana prompt generator. It runs locally, requires no sign-up, and uses no generation credits.
This guide gives you copy-ready templates for the tasks people most often struggle with:
- editing one part of an existing image
- preserving a person, character, or product
- generating product photography and ad variations
- placing readable text in posters and packaging
- combining multiple references
- preparing a final 4K render without wasting credits
Open the image editor when you are ready to use one. Generation is paid, but browsing and copying every prompt below is free.
The prompt formula
Use this structure for most image-editing jobs:
Use the uploaded image as the primary reference.
KEEP: [identity, product shape, logo, camera angle, pose, colors, or layout that must not change].
CHANGE: [the one specific transformation you want].
STYLE: [photorealistic, editorial, watercolor, 3D render, film still, and so on].
COMPOSITION: [framing, subject position, camera, background, and lighting].
OUTPUT: [aspect ratio, intended use, required text, and details to avoid].The KEEP line matters most. “Make this better” gives the model permission to reinterpret everything. A preservation list narrows the job.
Which model should you use?
| Task | Start with | Typical setting here | Credit cost |
|---|---|---|---|
| Quick concept or variation | Nano Banana | 1K | 4 |
| Reference-based edit | Nano Banana 2 | 2K | 12 |
| Product or campaign exploration | Nano Banana 2 | 1K or 2K | 8 or 12 |
| Poster with difficult text | Nano Banana Pro | 2K | 16 |
| Cost-effective 4K final | Nano Banana 2 | 4K | 18 |
| Complex typography or precise 4K layout | Nano Banana Pro | 4K | 32 |
Start at 1K or 2K while the idea is changing. Move to 4K only after the composition and prompt are stable. For a deeper comparison, see Nano Banana 2 vs Pro.
Photo editing prompts
For background replacement, object removal, portrait retouching, relighting, restoration, and failure-repair instructions, use the complete Nano Banana photo editing prompt guide.
1. Replace the background only
Use the uploaded photo as the source. Keep the person, face, hairstyle, clothing, pose, body proportions, and camera angle unchanged. Replace only the background with a quiet modern hotel lobby at golden hour. Add realistic contact shadows and warm window light that matches the original subject. Do not retouch the face or change the outfit.2. Change clothing while preserving identity
Preserve the same person, facial structure, skin tone, hairstyle, expression, pose, hands, and framing. Change only the clothing to a tailored charcoal business suit with a white shirt. Match the original light direction and fabric folds. Keep the result photorealistic and do not alter age or body shape.3. Remove an unwanted object
Remove only the red bag on the floor. Reconstruct the floor texture, shadows, and background behind it so the edit is invisible. Keep every person, object, reflection, crop, and color unchanged.4. Turn daytime into evening
Keep the architecture, street layout, vehicles, signs, and camera position unchanged. Transform the scene from midday to blue hour after sunset. Add realistic illuminated windows, streetlights, subtle wet-road reflections, and a deep blue sky. Preserve all existing text exactly.5. Restore an old portrait
Restore this portrait while preserving the subject's identity and original period. Remove scratches, dust, stains, and fold marks. Recover natural contrast and fine facial detail without smoothing the skin or inventing modern clothing. Colorize with restrained, historically plausible colors.Product photography prompts
For preservation rules, category-specific templates, and an approval checklist, use the full Nano Banana product photography prompt guide.
6. Clean ecommerce hero
Use the uploaded product as the exact reference. Preserve its shape, proportions, materials, label text, logo placement, and brand colors. Place it upright on a seamless warm-white studio background with a soft shadow beneath it. Use diffused commercial lighting, crisp edges, and a centered 4:5 composition. Do not add props or extra text.7. Premium lifestyle scene
Keep the product and packaging unchanged. Place it on a pale travertine bathroom counter beside folded white towels and a small eucalyptus branch. Use soft morning window light, realistic reflections, and shallow depth of field. The product must remain the sharp focal point and occupy about 40 percent of the frame.8. Three ad variations in one visual direction
Preserve the product, logo, label, and brand colors exactly. Create a premium campaign image with the product centered on a sculptural pedestal. Use a deep cobalt background, one hard side light, and a subtle atmospheric haze. Leave clean negative space in the upper left for ad copy. Do not render any text.Run the same prompt again with only the background color, camera height, or prop changed. Changing one variable per iteration makes results easier to compare.
9. Transparent-looking catalog cutout
Isolate the product from the uploaded image. Preserve all edges, transparent materials, reflective surfaces, label details, and proportions. Place it on a pure white background with a very soft natural grounding shadow. No border, props, hands, or text. Centered square catalog composition.10. Food menu photograph
Create a photorealistic overhead menu photograph of [dish]. Use natural ingredient texture, appetizing but believable color, and soft side lighting. Plate it on [plate description] over a neutral table surface with minimal props. Leave the right third uncluttered for pricing and menu copy. 4:5 vertical layout.Character consistency prompts
For reference-set planning, multi-character scenes, and a repeatable identity-lock block, read the complete Nano Banana character consistency prompt guide.
11. Same character, new location
Use the reference as the character identity sheet. Preserve the same facial structure, eye color, hairstyle, age, body proportions, outfit, and accessories. Place the character in a rainy Tokyo side street at night, walking toward the camera. Use cinematic neon reflections and a 35mm film look. Do not redesign the character.12. Same character, different pose
Keep the character design and clothing exactly consistent with the reference. Change only the pose to sitting cross-legged on the floor while reading a book. Maintain the same face, hair silhouette, color palette, illustration style, and line weight. Full-body view on a simple background.13. Character turnaround sheet
Create a clean character turnaround sheet based on the reference: front view, three-quarter view, side view, and back view. Preserve identity, proportions, costume construction, colors, and accessories across all four views. Neutral standing pose, even studio lighting, plain light background, no extra characters.14. Expression sheet
Create a six-panel expression sheet for the referenced character: neutral, happy, worried, angry, surprised, and laughing. Keep facial proportions, hairstyle, clothing, camera distance, art style, and lighting consistent in every panel. Label each expression with small clear text beneath the portrait.15. Consistent storybook scene
Preserve the referenced child's face, hairstyle, yellow raincoat, red boots, and watercolor illustration style. Show the child discovering a tiny glowing door at the base of an old oak tree. Wide storybook composition, gentle morning fog, warm light from the door, and room at the top for narration. No other people.Text and poster prompts
Text-heavy images often need more retries. Quote the exact copy, keep it short, and state the hierarchy. Start with Nano Banana 2 for simple text; use Nano Banana Pro when spelling or layout remains difficult.
16. Event poster
Design a vertical 4:5 poster for an independent film night. Use only this exact text:
"AFTER DARK"
"FRIDAY 18 OCTOBER"
"DOORS 7 PM"
Make "AFTER DARK" the largest line. Use condensed cream typography over a grainy midnight-blue city photograph, with strong hierarchy and generous margins. Do not add any other words, logos, dates, or symbols.17. Restaurant menu cover
Create an elegant square menu cover with only the exact words "MORI" and "SEASONAL KITCHEN". Use a restrained Japanese editorial style, warm off-white paper texture, one small ink illustration of a persimmon branch, and dark charcoal type. Correct spelling is mandatory. No additional text.18. Product feature graphic
Create a clean 16:9 product feature graphic. Place the referenced product on the right. On the left, render exactly:
"LIGHTER. QUIETER. LONGER."
"Up to 18 hours"
Use a modern sans-serif typeface, high contrast, a pale gray background, and three subtle technical callout lines. Preserve the product design and do not invent logos or certifications.19. Packaging concept
Create a front-facing packaging concept for a specialty tea called "NORTH GARDEN". Include only:
"NORTH GARDEN"
"JASMINE GREEN TEA"
"20 SACHETS"
Use botanical line art, deep green and warm ivory, a premium uncoated-paper texture, and a clear retail hierarchy. Keep every word exactly spelled. No health claims, badges, or extra copy.20. Simple infographic
Create a horizontal three-step infographic titled "FROM BRIEF TO FINAL". Use exactly these steps:
"1. Define"
"2. Generate"
"3. Refine"
Connect the steps with a simple arrow. Use large readable text, one icon per step, a white background, dark navy type, and one purple accent color. Do not add statistics or explanatory copy.Multi-image composition prompts
21. Put a product into a reference scene
Use image 1 as the exact product reference and image 2 as the environment reference. Insert the product naturally into the scene from image 2. Preserve the product's shape, label, logo, and colors. Match the scene's camera perspective, light direction, reflections, depth of field, and contact shadows. Remove the object currently occupying that position.22. Combine wardrobe and person references
Use image 1 for the person's identity and image 2 for the complete outfit. Preserve the face, hair, skin tone, age, body proportions, and pose from image 1. Dress the person in the exact garments, colors, materials, and accessories from image 2. Match the original portrait lighting and background.23. Interior redesign from two references
Use image 1 as the room structure and camera view. Use image 2 only as the style reference. Preserve the windows, doors, ceiling height, floor plan, and camera position from image 1. Redesign the furniture, materials, lighting, and color palette in the warm minimalist style of image 2. Keep the result architecturally plausible.Final-output prompts
24. Refine without redesigning
Treat this as a final refinement pass, not a redesign. Preserve the subject, identity, composition, camera angle, colors, text, and all object positions. Improve only fine texture, edge quality, realistic material detail, subtle lighting transitions, and small artifacts. Do not add or remove elements.25. Prepare a 4K marketing final
Create the final high-detail version of this approved composition. Keep the layout, crop, subject identity, product design, logo, required text, and color palette unchanged. Increase realistic material detail, clean edges, typography clarity, and lighting quality for a 4K marketing asset. Avoid oversharpening, plastic skin, extra text, and invented objects.How to fix a prompt that is not working
Do not rewrite everything after a weak result. Diagnose the failure:
| Failure | Add or change this |
|---|---|
| Identity changed | List the exact facial, hair, clothing, and proportion details to preserve |
| Product changed | State that shape, label, logo, materials, and colors are locked |
| Too many objects changed | Say “change only…” and “keep every other element unchanged” |
| Text is misspelled | Quote the exact copy, reduce word count, and forbid extra text |
| Composition is random | Specify camera, framing, subject position, and negative space |
| Edit looks pasted in | Ask to match perspective, light direction, shadows, and reflections |
| Results drift between runs | Reuse the same references and change one prompt variable at a time |
A credit-conscious workflow
- Pick the closest prompt above and replace every bracketed detail.
- Use Nano Banana for a cheap concept or Nano Banana 2 for reference editing.
- Generate at 1K or 2K while composition is unsettled.
- Change one variable at a time.
- Move to Pro only for a specific unresolved problem such as difficult text or precise layout.
- Use 4K only for the approved final.
The editor displays the exact cost before each run. If a charged generation request fails, the reserved credits are returned automatically.
