Best Prompts for Nano Banana Pro: 20+ Ready to Copy

AI image generation has reached a new level with Nano Banana Pro, the image model powering Gemini 3 Pro. Unlike previous generators, this model understands physics, lighting, and—for the first time reliably—text within images.

This guide compiles the most effective prompts for Nano Banana Pro, organized by use case and ready to copy. Each prompt includes optimal aspect ratio and quality settings to maximize your results, and you can paste any of them straight into ilisai's AI image generator and adjust from there.

What's inside

This guide collects more than 20 ready-to-use prompts across eight use cases, each with its recommended aspect ratio and quality settings.

• Professional photography: Corporate headshots, product shots, lifestyle
• Image editing: Background changes, object removal, quality enhancement
• Design & creativity: Infographics, logos, architectural renders
• E-commerce: Product photography and virtual try-on
• Social media: Thumbnails, posters, viral content

Every prompt below runs in a browser, no API key involved: where to run Nano Banana Pro prompts for free covers the models available, the settings, and what each image costs in credits.

Aspect ratio and quality: How to choose

Match the aspect ratio to the destination — vertical (9:16, 4:5) for social feeds and Stories, horizontal (16:9, 21:9) for video and cinematic shots, square (1:1) for avatars and e-commerce — and the quality to the final use: 2K for web and social media, 4K for print and client deliverables. When editing an existing image, keep its original ratio to avoid unexpected crops.

Nano Banana Pro lets you configure two key parameters that significantly affect output:

Available aspect ratios

Quality levels

Professional photography

To get a professional portrait from Nano Banana Pro, attach a reference photo, instruct the model to preserve the subject's facial identity, and describe the camera, lens, and lighting setup you want. Corporate headshots work best at 1:1 or 4:5 in 4K; analog film portraits at 3:2 or 2:3; Y2K-era looks at 2K, where the lower resolution reinforces the aesthetic.

These prompts use real photography terminology: lighting setups, lenses, and camera styles. This enables Nano Banana Pro to generate studio-quality results.

If portraits are the whole job, our Nano Banana Pro headshot prompts go further than the three below: LinkedIn and CV photos, team shots, and corporate, creative or outdoor styles.

Corporate headshot (LinkedIn / Personal Branding)

Transform any casual photo into a professional studio portrait.

Settings: 1:1 or 4:5 · 4K

The 1:1 ratio is ideal for LinkedIn profile photos. Use 4:5 when you need more body context (shoulders, blazer). 4K quality ensures professional sharpness in facial details.

1Preserve the subject's facial identity from the attached image with complete accuracy. Dress them in an elegant charcoal gray blazer over a light blue oxford shirt.
2
3Setting: Professional studio backdrop in deep charcoal with a soft radial gradient—brighter at center, darkening toward the edges.
4
5Photography technique: Shot with a Canon R5 and 85mm f/1.2 lens, achieving natural and flattering facial compression.
6
7Lighting setup: Classic configuration with soft key light at 45 degrees creating defined facial modeling. Subtle fill light to soften shadows. Rim light separating the subject from the background.
8
9Critical details: Authentic skin texture with visible pores and micro-details—avoid the airbrushed look. Natural catchlights in both eyes. The blazer fabric should show its characteristic wool texture.
10
11Output: Photorealistic executive portrait.

Analog film aesthetic

Generate a portrait with the distinctive look of analog film.

Settings: 3:2 or 2:3 · 4K

The 3:2 ratio replicates the 35mm film format, reinforcing the analog aesthetic. Use 2:3 for vertical orientation. 4K allows you to appreciate the simulated film grain.

1Preserve the subject's facial features exactly as they appear in the original image.
2
3Aesthetic: Intimate portrait with Kodak Portra 800 characteristics—warm skin tones, slightly lifted shadows, organic highlight rolloff.
4
5Location: By a large window in a Brooklyn brownstone apartment. Late afternoon side light creating soft but defined contrast.
6
7Atmosphere: Visible but elegant film grain. Selective focus on the eyes with gentle falloff toward the frame edges.
8
9Pose: Subject leaning casually against the window frame, contemplative gaze directed toward the light, serene and thoughtful expression.
10
11Quality: Shallow depth of field, creamy bokeh in out-of-focus areas, overall warm tonality.

Y2K nostalgic portrait

Recreate the aesthetic of early 2000s digital photography.

Settings: 3:4 or 4:5 · 2K

Vertical ratios 3:4 and 4:5 emulate the proportions of point-and-shoot digital cameras from that era. 2K maintains that characteristic "imperfect" resolution—4K would be too crisp for this aesthetic.

1Keep the subject's face unaltered from the reference image.
2
3Generate a portrait with early 2000s point-and-shoot digital camera aesthetic: characteristic direct flash, slight highlight blowout, slightly oversaturated colors.
4
5Subject wears a vintage band t-shirt with hair casually pulled back. Natural, carefree expression.
6
7Environment: Early 2000s teenage bedroom with shelves full of CDs, movie posters from the era, a lava lamp visible in the background.
8
9The flash creates that characteristic skin shine and hard reflections on glossy surfaces. Era-typical resolution—sharp detail but without modern camera perfection.

E-commerce and product photography

Nano Banana Pro covers the two core e-commerce jobs: isolating a product onto a clean catalog background and compositing a garment onto a model with realistic fabric physics. Use 1:1 at 4K for marketplace listings — square, high-resolution images hold up well under product zoom — and 2:3 or 4:5 for fashion try-on shots.

These prompts enable professional product photography without expensive photo shoots.

The full e-commerce set — white-background packshots, lifestyle scenes, flat lays, and the mistakes that cost sellers a listing — is in our Nano Banana Pro product photography prompts.

Catalog-ready product photography

Turn any product photo into a professional catalog image.

Settings: 1:1 or 4:5 · 4K

The 1:1 ratio is the e-commerce standard (Amazon, Etsy, Shopify). 4:5 works well for vertically-oriented products. 4K is essential for product zoom and texture detection.

1Detect and isolate the main product from the provided photograph, removing any distracting elements: hands, cluttered surfaces, or inappropriate backgrounds.
2
3Extraction: Clean product cutout with perfectly defined edges, no residue from the original background.
4
5Presentation: Place the product on an infinite white surface (digital cyclorama background). Add a realistic and subtle contact shadow at the base to ground the object without distraction.
6
7Lighting: Commercial studio setup with softboxes—wrap-around lighting that reveals textures and materials without creating harsh specular highlights.
8
9Post-processing: Correct any lens distortion, optimize sharpness on product details, neutral and accurate white balance.

Virtual fashion try-on

Visualize how a garment looks on a specific model.

Settings: 2:3 or 4:5 · 4K

The 2:3 ratio is ideal for full-body fashion photography. 4:5 works better for half-body shots. 4K ensures fabric textures are believable.

1Combine Image A (garment photographed separately) with Image B (model) to create a convincing fashion photograph where the model wears the garment.
2
3Fabric physics: The garment must behave realistically—conforming to the model's anatomy, creating natural folds at flex points, draping with correct weight for the material.
4
5Product fidelity: Accurately reproduce the color, texture, patterns, and any brand details visible in Image A.
6
7Light integration: The garment must receive the same lighting as the model in Image B—consistent color temperature, coherent shadow direction, appropriate highlights and reflections for the material.
8
9Style: Editorial fashion photography, full-body composition, neutral background, magazine quality.

Image editing

Three editing jobs cover most real-world needs: extending the frame (outpainting to 21:9), cleaning distracting elements out of backgrounds, and targeted modifications of a single object. Keep the original aspect ratio while editing and use 4K so the generated fill is indistinguishable from the source.

Nano Banana Pro can edit existing images with natural language commands. No external tools needed for specific changes.

Smart frame extension

Expand an image by generating coherent content in the extended areas.

Settings: 21:9 · 4K

The 21:9 ultrawide ratio is perfect for wallpapers and cinematic headers. 4K maximizes detail in generated areas.

1Extend this photograph to fit a 21:9 panoramic format (ultrawide).
2
3Visual coherence: Generate new content on both sides that naturally continues the existing scene. Respect the perspective, vanishing lines, and spatial logic of the original frame.
4
5Continuity: If there are partially visible elements at the edges (architecture, vegetation, cropped people), complete their form logically and naturally.
6
7Preservation: The original center area must remain intact—no alterations, distortions, or color changes.
8
9Lighting: Generated areas must maintain identical light conditions: same time of day, same shadow direction, same color temperature.

Background cleanup

Remove unwanted elements from a photograph's background.

Settings: Keep original ratio · 4K

When editing existing images, maintain the original aspect ratio to avoid unexpected crops. 4K ensures the generated fill is indistinguishable from original content.

1Remove all people visible in the background behind the main subject.
2
3Reconstruction: Fill the empty areas with elements coherent with the environment—if it's a street, continue the pavement and facades; if it's nature, extend vegetation and terrain.
4
5Quality: The fill must be indistinguishable from original content. No smudges, visible edges, or texture inconsistencies. Same focus level and grain as the rest of the image.
6
7Result: A photograph that appears to have been taken in an empty location, not edited afterwards.

Targeted modifications

Change specific elements without affecting the rest of the composition.

Settings: Keep original ratio · 2K or 4K

For minor changes, 2K offers good speed. Use 4K if the modified element is the main focus.

1Transform the white SUV in the image into a black Rivian R1S, maintaining its exact position and angle.

1Place round tortoiseshell reading glasses on the subject's face, naturally adjusted to their facial anatomy.

1Upscale this image to 4K resolution: reduce digital noise while preserving details, selectively increase sharpness on the main subject, and optimize dynamic range.

Design and infographics

Nano Banana Pro renders legible text inside images reliably — the historical weak point of AI image generators — which makes it usable for diagrams, infographics, and logo concepts. Use 2K for flat vector-style diagrams and 1:1 at 4K for logos that need crisp edges at small sizes.

One of Nano Banana Pro's standout capabilities is handling text within images.

Educational diagram

Transform complex concepts into clear visualizations.

Settings: 4:3 or 16:9 · 2K

The 4:3 ratio works well for educational presentations. Use 16:9 if it will be used in slides or video. 2K is sufficient for vector-style diagrams—text renders well at this resolution.

1Design an educational diagram explaining the carbon cycle.
2
3Visual components: Show the sun, plants, animals, decomposers, ocean, atmosphere, and arrows indicating carbon dioxide absorption, photosynthesis, respiration, and decomposition.
4
5Graphic style: Modern flat vector illustration with clean colors, suitable for a high school science textbook. Clean lines, natural greens and blues palette.
6
7Text: Label each phase of the cycle in English with legible sans-serif typography. Scientific terms in bold.

Basic brand identity

Generate logo concepts with integrated text.

Settings: 1:1 · 4K

Logos should be generated at 1:1 for maximum versatility. 4K ensures crisp edges and perfectly legible text even at small sizes.

1Create a minimalist logo for an artisan coffee roastery called 'Morning Ritual'.
2
3Concept: Combine an abstract coffee bean icon with a subtle sunrise element. Clean design that works in both positive and negative.
4
5Typography: Geometric sans-serif with medium weight for 'MORNING', light weight for 'ritual'. Wide tracking for elegance.
6
7Colors: Primary version in deep espresso brown (#3D2314) on white background. Include monochrome version as well.

Interior design and architecture

From a 2D floor plan, Nano Banana Pro can produce a photorealistic render, furnish an empty room for a real-estate listing, or swap wall and floor materials on request. Use 16:9 at 4K for client-facing renders; 2K is enough for quick material iterations.

These prompts enable visualization of spaces and architectural projects.

Floor plan to photorealistic render

Generate a render from a 2D floor plan.

Settings: 16:9 · 4K

The 16:9 ratio is standard for architectural presentations. 4K is essential for professional renders where clients need to see material and finish details.

Test different finishes in a space.

Settings: Keep original ratio · 2K

For quick material iterations, 2K offers good generation speed. Use 4K only for the final approved version.

1Replace the current wall paint behind the bed with exposed brick texture. Keep everything else the same.

Social media and marketing

For social creatives, match the format to the platform: 16:9 at 2K for YouTube thumbnails, 4:5 or 9:16 at 4K for Instagram posters and Stories. Thumbnails never need 4K — they are displayed at reduced sizes — while printed promotional material does.

Generate social media creatives quickly and professionally.

Video thumbnail (YouTube/TikTok)

Create thumbnails that grab attention and boost CTR.

Settings: 16:9 · 2K

YouTube uses 16:9 for thumbnails (1280x720). 2K is sufficient since thumbnails are viewed at reduced sizes—4K would be unnecessary.

1Create an attention-grabbing video thumbnail using the person from the attached image.
2
3Expression: Transform their facial expression to one of genuine amazement—wide eyes, raised eyebrows, slightly open mouth. Keep their facial features identical.
4
5Composition: Subject positioned in the left third of the frame, gesturing with their hand toward the right side where [a spectacular homemade burger] appears.
6
7Graphic elements: Bold red arrow connecting the person's gesture to the burger. Zoom effect/motion lines around the burger.

9Typography: Large text 'GAME CHANGER!' in white impact font with thick black outline, positioned in the upper center area.
10
11Style: Hypersaturated colors, elevated contrast, blurred kitchen background with warm tones.

Promotional poster

Design promotional material with perfectly integrated text.

Settings: 4:5 or 9:16 · 4K

The 4:5 ratio is optimal for Instagram feed. 9:16 for Stories and vertical formats. 4K ensures text is crisp even in print.

1Create a promotional poster for a craft brewery.
2
3Main visual: Dramatic close-up of an amber ale being poured into a branded pint glass—golden liquid, white foam cascade, condensation droplets on the glass, against a dark wood bar background.
4
5Typography hierarchy:
6- Headline: 'Tap Takeover Tuesday' in bold vintage serif, copper/bronze color, at top.
7- Subhead: '$5 pints all day' in clean sans-serif, integrated in a minimal banner.
8- Footer: '@craftbrewery' in small, clean type.
9
10Integration: Text should respect depth of field—foreground elements slightly blurred over background text. Subtle shadows integrating typography into the scene.

Translation and visual localization

Nano Banana Pro can translate the text inside an image — menus, signage, comics — while preserving the original typography, textures, and layout. Keep the source document's aspect ratio and use 2K: legibility matters more than resolution here.

Nano Banana Pro can edit text within images while maintaining the original aesthetic.

Signage and menu translation

Translate visual content while preserving textures and style.

Settings: Keep original ratio · 2K

When translating, keep the document's original ratio. 2K is sufficient for most translations—focus is on legibility, not extreme detail.

1Translate the Korean text on this restaurant menu into English.
2
3Material preservation: The menu paper has a specific handmade texture—visible fibers, slight yellowing, irregular edges. The translated text should appear printed on that same surface, with slight fading or wear to match.
4
5Typography: Use a font that evokes Asian calligraphy but is legible in Latin characters. Maintain similar visual weight to the original.
6
7Prices: Keep numbers and the ₩ symbol exactly as they appear—don't convert currency.
8
9Layout: Respect the original arrangement—columns, spacing, visual hierarchies.

Illustrated content adaptation

Localize comics, memes, or graphic content to other languages.

Settings: Keep original ratio · 2K

Comics have varied ratios—keep the original. 2K preserves artistic style without adding artificial sharpness.

1Convert the text in this manga from Japanese to English.
2
3Process: Remove the original text from each speech bubble and dialogue box. Fill the space cleanly maintaining consistent background color.
4
5New typography: Use a comic sans-serif font that respects the original's visual style. Text should occupy similar space—adjust size if necessary to fit naturally.
6
7Sound effects: Translate those with English equivalents as well (ドキドキ→THUMP THUMP, バン→BANG). Maintain the original graphic style of each.

Creative experiments

These experiments test compositional control rather than realism: recursive Droste images, age progressions across five decades, scene generation from raw GPS coordinates, and collectible-figure conversions. Generate them at 4K so detail survives in the smallest parts of the composition.

These prompts explore the limits of what Nano Banana Pro can generate.

Picture within a picture (Droste Effect)

Generate recursive compositions with infinite loop effect.

Settings: 1:1 · 4K

The 1:1 ratio simplifies recursive geometry. 4K is necessary to maintain detail in smaller iterations.

1Create a recursive image: a man sitting in an armchair holds a tablet. On the tablet screen appears the same man in the same armchair holding the same tablet. The pattern repeats visibly for at least 4 levels of depth, each iteration smaller but detailed.

Temporal progression

Visualize a subject's evolution through time.

Settings: 16:9 or 3:2 · 4K

Horizontal ratios allow showing multiple stages in sequence. 4K ensures each stage has sufficient facial detail.

1Using the attached photo as reference, generate a sequence of 5 portraits showing this person at ages 25, 40, 55, 70, and 85. Maintain recognizable identifying features at each stage. Same framing and photographic style throughout the series.

Visual geolocation

Generate a scene based solely on coordinates.

Settings: 16:9 or 21:9 · 4K

Panoramic ratios work better for cityscapes and views. 4K captures architectural and atmospheric details.

140.7580° N, 73.9855° W — time: 19:30, month: October

3D collectible figure

Transform portraits into stylized vinyl toy characters.

Settings: 1:1 or 4:5 · 4K

Square or slightly vertical ratios work well for figures. 4K allows appreciating the glossy plastic finish.

1Convert the person in the photo into a Funko Pop-style collectible figure.
2
3Characteristics: Proportionally large head (1:2 ratio with body), large shiny eyes without detailed pupils, minimal nose, simplified body with short limbs.
4
5Recognition: Preserve key identifying elements—characteristic hairstyle, hair color, glasses if present, simplified clothing style.
6
7Rendering: Vinyl plastic finish with subtle shine, soft studio lighting, circular base included, pastel gradient background.
8
9Pose: Standing, frontal, friendly neutral expression.

Fill-in-the-blank templates for figurine renders, character sheets, and keeping one character recognizable across generations are in our Nano Banana Pro figurine prompts.

How to get the best results

Effective Nano Banana Pro prompts follow a five-part formula: subject, action or context, artistic style, technical parameters, and output settings. Longer, more specific prompts written in photography terminology consistently beat short generic ones — there is no length penalty.

The formula for effective Nano Banana Pro prompts:

1. Subject: What you want to generate
2. Action/Context: What it's doing or where it is
3. Artistic style: Photorealistic, illustration, vintage, etc.
4. Technical parameters: Lighting, lens, angle, color palette
5. Settings: Appropriate aspect ratio and quality for your use case

Basic example:

1A dog in a park

Optimized example:

Settings: 3:2 · 4K

1Photography of a golden retriever running toward the camera in an autumn park, dried leaves flying, sunlight filtering through the trees, shallow depth of field focusing on the dog's face. Action photography style, warm golden hour tones, editorial quality.

The model responds better when you use photography and cinema terminology. Describe the scene as a director of photography would, and choose the aspect ratio that best aligns with the type of image you're generating. The prompt gallery shows what this formula produces in practice: real images generated in ilisai, each with the exact prompt behind it.

To write your own from scratch instead of adapting the ones above, how to write prompts for Nano Banana Pro takes each of those five parts apart and rewrites three vague prompts into specific ones.
