Section 4: Advanced Editing, Restoration & Colorization

Nano Banana Pro excels at sophisticated image manipulation through natural conversation. This includes in-painting (removing or adding elements), restoration (repairing damaged photos), colorization (bringing B&W images and manga to life), and style transformation.

These capabilities position it as one of the most versatile AI image generators available for professional editing workflows.

Best Practices for Advanced Editing

Semantic Instructions: Forget manual masking—simply describe what you want changed in natural language. The model understands context and boundaries automatically.

Physics Awareness: Test the model's understanding with complex physical transformations like "fill this empty glass with sparkling water and ice cubes"—it comprehends material properties and lighting interactions.

Example Prompts

Intelligent Object Removal: "Remove all tourists from the background of this landmark photo. Fill the empty spaces with contextually appropriate textures—matching cobblestones for the ground and period-accurate storefronts for the buildings—that blend seamlessly with the surrounding environment."

Manga & Comic Colorization: "Colorize this black and white manga panel using a vibrant anime-style palette. Ensure the energy beam effects glow with intense neon blue, and apply the character's official color scheme to their costume. Maintain the original linework integrity."

Creative Localization: "Adapt this London bus stop advertisement concept for a Tokyo setting. Translate the tagline into natural Japanese, and transform the background into a bustling Shibuya intersection at night with authentic neon signage and urban atmosphere."

Seasonal & Lighting Transformation: "Transform this summer scene into deep winter. Preserve the exact architectural details of the house, but add realistic snow accumulation on the roof and yard. Shift the lighting to evoke a cold, overcast late afternoon with appropriate shadow angles."

Section 5: Dimensional Translation (2D ↔ 3D)

One of Nano Banana Pro's most impressive capabilities is translating between dimensional formats—converting 2D schematics into photorealistic 3D visualizations, or transforming 3D concepts into stylized 2D artwork.

This makes it an invaluable AI image generator for interior designers, architects, game developers, and meme creators alike.

Example Prompts

Floor Plan to Interior Design Presentation:

"Based on this uploaded 2D floor plan, generate a professional interior design presentation board as a single cohesive image.

Layout: Create a collage featuring one large hero image at the top (wide-angle perspective of the main living area), with three smaller images below (Master Bedroom, Home Office, and a 3D isometric floor plan view).

Style: Apply a Modern Minimalist aesthetic with warm oak wood flooring and soft off-white walls consistently across ALL rendered spaces.

Quality: Photorealistic rendering with soft, natural window lighting."

Meme to 3D Conversion: "Transform the classic 'This is Fine' dog meme into a photorealistic 3D render. Maintain the exact original composition and framing, but render the dog as a plush toy with realistic fabric texture, and the surrounding flames as convincing real fire with proper lighting and smoke effects."

Product Concept Visualization: "Convert this rough product sketch into a professional 3D product render suitable for investor presentations. Apply realistic materials—brushed aluminum for the body, matte black rubber for grips—with studio lighting and subtle reflections."

Section 6: High-Resolution & Texture Generation

Nano Banana Pro supports native output from 1K up to stunning 4K resolution. This capability is essential for detailed texture work, large-format printing, and professional asset production where quality cannot be compromised.

Best Practices for High-Resolution Output

Explicit Resolution Requests: When your workflow supports it, specifically request 2K or 4K output for maximum detail.

Texture Descriptions: Articulate fine details including imperfections, surface variations, and material properties to leverage the model's high-fidelity capabilities.

Example Prompts

4K Environment Texture: "Harness native high-fidelity output to create a breathtaking, atmospheric environment of a mossy forest floor after rainfall. Render complex dappled lighting effects and delicate organic textures, ensuring every strand of moss, dewdrop, and shaft of light achieves pixel-perfect clarity suitable for 4K desktop wallpaper."

Product Detail Shot: "Generate a macro product photograph of a luxury mechanical watch face at 4K resolution. Capture the intricate movement visible through the exhibition caseback, with realistic reflections on polished steel and subtle scratches on the crystal that convey authenticity."

Architectural Visualization: "Create a hyper-detailed 4K render of a modern concrete and glass residence at golden hour. Emphasize material textures—the subtle aggregate in exposed concrete, fingerprints on glass surfaces, weathering on copper accents—for photorealistic authenticity."

---

Section 7: Thinking & Reasoning Mode

Nano Banana Pro employs a unique "Thinking" process by default, generating intermediate conceptual images (not charged) to refine composition before producing the final output. This enables sophisticated data analysis and visual problem-solving that sets it apart from conventional AI image generators.

Example Prompts

Mathematical Visualization: "Solve a complex logarithmic equation in the complex plane, presented as a hand-written whiteboard solution. Show each step clearly with proper mathematical notation and brief explanatory annotations."

Analytical Reasoning: "Analyze this photograph of a finished room and generate a 'before' image showing what this space likely looked like during construction—exposed framing, unfinished drywall, visible electrical and plumbing rough-ins, construction debris on the subfloor."

Deductive Visualization: "Based on this archaeological artifact photograph, generate a visualization of how the complete, undamaged original object likely appeared when newly crafted, including restored missing sections and original surface finish."

Section 8: One-Shot Storyboarding & Concept Art

Nano Banana Pro can generate sequential narrative art and professional storyboards without requiring a grid template, ensuring cohesive visual storytelling within a single session. This capability has also become popular for creating "movie concept art" style imagery.

This makes it an exceptional AI image generator for filmmakers, game designers, advertisers, and content creators developing visual narratives.

Example Prompts

Luxury Brand Campaign Storyboard:

"Create a captivating 9-part visual narrative featuring a sophisticated woman and man in an award-winning luxury luggage commercial.

Story Arc: Include emotional peaks and valleys throughout the journey, culminating in an elegant closing shot featuring the woman with the brand logo prominently displayed.

Consistency Requirements: The identities, facial features, and attire of both characters must remain absolutely consistent throughout all 9 images.

Visual Variety: Vary camera angles, distances, and character expressions across the sequence to create dynamic visual interest.

Format: Generate images one at a time. Ensure every image maintains 16:9 landscape aspect ratio."

Product Launch Sequence: "Develop a 6-image storyboard for a smartphone launch video. Progress from mysterious silhouette reveal, through feature highlights, to lifestyle integration, ending with the product hero shot. Maintain consistent lighting style and color grading throughout."

Character Journey: "Create an 8-panel visual story following a young entrepreneur from initial idea sketch, through late-night coding sessions, investor rejections, breakthrough moment, to successful product launch. Maintain character consistency while showing the passage of time through subtle aging and wardrobe evolution."

Section 9: Structural Control & Layout Guidance

Input images for Nano Banana Pro aren't limited to character references or editing subjects. You can use reference images to precisely control composition and layout of the final output—a transformative capability for designers who need to convert napkin sketches, wireframes, or specific grid layouts into polished professional assets.

Best Practices for Layout Control

Sketches & Drafts: Upload hand-drawn sketches to define exact positioning of text, subjects, and design elements.

Wireframes: Use screenshots of existing layouts or UI wireframes to generate high-fidelity mockups.

Grid Systems: Use grid reference images to force the model to generate assets for tile-based games, LED displays, or structured layouts.

Example Prompts

Sketch to Final Advertisement: "Create a polished advertisement for [product] following the exact composition and element placement shown in this rough sketch. Maintain the indicated proportions and positioning while elevating to professional quality."

Wireframe to UI Mockup: "Transform this wireframe into a high-fidelity UI mockup for a premium fitness app. Apply a dark theme with accent colors, realistic content, and appropriate iconography while respecting the exact layout structure provided."

Pixel Art & LED Display: "Generate a pixel art sprite of a majestic unicorn that fits precisely within this 64x64 grid image. Use high-contrast, vibrant colors optimized for LED display visibility."

(Developer tip: Extract the center color value of each grid cell programmatically to drive a connected 64x64 LED matrix display.)

Animation Sprite Sheet: "Create a sprite sheet showing a character performing a backflip, arranged in a 3x3 grid. Each cell should represent one frame of the animation sequence in chronological order. Maintain square aspect ratio and follow the exact grid structure of the attached reference."

(Tip: Extract individual cells to create animated GIFs or game sprites.)
