Multi-Image Composition with Nano Banana 2: Advanced Techniques

Nano Banana 2 goes well beyond text-to-image generation. This guide covers the advanced multi-image composition workflows that make it genuinely powerful — and shows you how to use them effectively.

Beyond Single-Image Generation

Text-to-image on its own is useful, but Nano Banana 2's real capability surface appears when you feed it multiple images at once. Working across several inputs unlocks workflows that are impractical or outright impossible with conventional editing tools.

This guide covers six core techniques:

• Seamless image blending
• Element extraction and placement
• Style transfer and artistic fusion
• Reference-based generation
• Complex scene assembly
• Character consistency across contexts

Understanding Multi-Image Capabilities

What Sets Nano Banana 2 Apart

Traditional photo editing requires manual masking, layer management, and hand-tuned blending. Nano Banana 2 handles the hard parts automatically because it understands:

• Spatial relationships between objects in a scene
• Lighting direction and perspective coherence
• Style and tonal harmony
• Contextual logic of scenes

That contextual understanding means you can describe a composition in plain language and get a convincing result — no manual brushwork required.

Types of Multi-Image Operations

1. Image Blending — Merge two or more images into a single cohesive output.

2. Element Extraction and Placement — Pull a specific object from one image and insert it naturally into another scene.

3. Style Transfer — Map the visual treatment of one image onto the content of another.

4. Reference-Based Generation — Use existing images to constrain and guide new image creation.

5. Scene Assembly — Build up complex compositions by combining multiple source elements.

6. Character Consistency — Reproduce the same character or object faithfully across different contexts.

Technique 1: Seamless Image Blending

Basic Blending Workflow

Goal: combine two images so the join is undetectable.

1. Select source images
   - Choose images with compatible lighting
   - Consider color palette harmony
   - Ensure resolution compatibility
2. Upload both images to Nano Banana 2
3. Write blending prompt:
   "Blend these two images seamlessly, maintaining natural lighting
   and perspective, creating a cohesive single scene"
4. Review and refine
   - Adjust blend strength if available
   - Modify prompt for better results
   - Generate variations

Advanced Blending Techniques

Weighted Blending — Control the balance between source images:

Prompt: "Blend these images with 70% emphasis on the first image,
maintaining the background from image 1 while incorporating
the subject from image 2"

Contextual Blending — Specify how content from each image should be integrated:

Prompt: "Merge these images by placing the person from image 1
into the environment from image 2, adjusting lighting and
shadows to match the scene naturally"

Mood-Preserved Blending — Lock in the emotional tone across the merge:

Prompt: "Blend these images while preserving the warm, cozy
atmosphere, ensuring color temperature remains consistent
throughout the composition"

Practical Blending Use Cases

Use Case 1: Product Visualization

Drop a product into a lifestyle environment:

Image 1: Product on white background
Image 2: Lifestyle scene (kitchen, office, etc.)
Prompt: "Place the product from image 1 naturally into the
scene from image 2, matching lighting and creating appropriate
shadows and reflections"
Result: Professional product-in-context imagery

Use Case 2: Landscape Enhancement

Combine strong skies with strong foregrounds:

Image 1: Beautiful sky with dramatic clouds
Image 2: Interesting foreground scene
Prompt: "Combine the dramatic sky from image 1 with the
landscape from image 2, blending the horizon naturally and
maintaining consistent lighting throughout"
Result: Stunning composite landscape

Use Case 3: Before/After Transformation

Produce split-view comparison assets:

Image 1: Before state
Image 2: After state
Prompt: "Create a side-by-side or split-screen composition
showing both images with a clear, elegant transition between them"
Result: Compelling transformation story

Technique 2: Element Extraction and Composition

Isolating and Placing Elements

One of Nano Banana 2's strongest capabilities is identifying a specific element in one image and placing it convincingly into a completely different scene — adjusting scale, lighting, and perspective automatically.

Single Element Placement

Step 1: Upload source image containing desired element
Step 2: Upload target scene
Step 3: Describe the composition
Prompt: "Take the [specific element] from the first image
and place it [location] in the second image, adjusting
scale, lighting, and perspective to look natural"

Example — Character Placement:

Image 1: Portrait of a person
Image 2: Coffee shop interior
Prompt: "Place the person from the first image sitting at
the corner table in the coffee shop scene, adjusting lighting
to match the ambient interior light, with natural shadows"
Result: Person appears as if originally photographed in that location

Multiple Element Composition

Image 1: Subject/character
Image 2: Background environment
Image 3: Props or additional elements
Prompt: "Create a composition with the character from image 1
in the environment from image 2, incorporating the elements
from image 3 naturally into the scene, ensuring cohesive
lighting and realistic spatial relationships"

Advanced Element Techniques

Perspective Matching:

Prompt: "Place the object from image 1 into image 2, adjusting
the viewing angle and perspective to match the scene's vanishing
points, with appropriate foreshortening"

Lighting Adaptation:

Prompt: "Insert the subject from image 1 into the scene from
image 2, completely re-lighting the subject to match the
directional lighting, color temperature, and shadow patterns
of the target environment"

Scale and Proportion Control:

Prompt: "Place the object from image 1 into image 2 at
approximately 1/3 the height of the background building,
ensuring realistic depth and atmospheric perspective"

Technique 3: Style Transfer and Artistic Fusion

How Style Transfer Works

Style transfer extracts the visual characteristics of one image — texture, stroke quality, color treatment — and applies them to the subject matter of another. The content stays; the rendering changes.

Basic Style Transfer

Image 1: Content (what you want to show)
Image 2: Style reference (how you want it to look)
Prompt: "Apply the artistic style, color palette, and visual
treatment of image 2 to the content of image 1, maintaining
the subject and composition while transforming the aesthetic"

Style Transfer Applications

Brand Consistency:

Image 1: New photo shoot
Image 2: Established brand image
Prompt: "Transform image 1 to match the color grading, lighting
style, and overall aesthetic of image 2, ensuring brand visual
consistency"
Use: Maintaining cohesive brand galleries and campaigns

Artistic Interpretation:

Image 1: Photograph
Image 2: Painting or artistic work
Prompt: "Reimagine the photograph from image 1 in the artistic
style of image 2, applying similar brushwork, color treatment,
and compositional approach while keeping the photographic subject"
Use: Creating unique artistic content from photos

Historical or Vintage Effects:

Image 1: Modern photo
Image 2: Historical photo with desired era characteristics
Prompt: "Apply the vintage aesthetic, grain, color palette,
and photographic characteristics of image 2 to image 1,
creating a historically consistent appearance"
Use: Period-appropriate content creation

Advanced Style Techniques

Partial Style Application:

Prompt: "Apply the style from image 2 to image 1, but only to
the background, keeping the main subject in original photographic
style for contrast"

Style Blending:

Image 1: Content
Image 2: Style reference A
Image 3: Style reference B
Prompt: "Apply a blended style combining 60% of the aesthetic
from image 2 and 40% from image 3 to the content of image 1"

Selective Style Strength:

Prompt: "Apply the style from image 2 to image 1 with moderate
intensity (50%), maintaining some photographic realism while
incorporating artistic characteristics"

Technique 4: Reference-Based Generation

Using Images as Generation Guides

Rather than blending or transforming existing images, reference-based generation uses your source material as constraints that shape entirely new output. The model reads the references and produces something novel that still respects what you've shown it.

Character Reference Workflow

Step 1: Upload reference image of character
Step 2: Describe new scene
Prompt: "Using the character appearance from the reference
image (same facial features, hair, clothing), generate a new
image showing this character [in new situation/context],
maintaining exact character consistency"

Example Series:

Reference: Portrait of a robot character
Generation 1:
Prompt: "The character from the reference image working
on a laptop in a modern office"
Generation 2:
Prompt: "The same character from the reference relaxing
on a beach at sunset"
Generation 3:
Prompt: "The character from the reference exercising
in a gym"
Result: Consistent character across completely different scenes

Style Reference Generation

Reference: Image with desired visual style
Prompt: "Generate a new image of [new subject] in the same
visual style, color palette, lighting approach, and overall
aesthetic as the reference image"
Result: New content that feels part of the same visual family

Compositional Reference

Reference: Image with ideal composition
Prompt: "Generate an image of [new subject] following the
compositional structure, framing, and spatial arrangement
of the reference image"
Result: New content with proven compositional effectiveness

Multiple Reference Approach

Image 1: Character reference (who)
Image 2: Style reference (how it looks)
Image 3: Compositional reference (layout)
Prompt: "Generate an image featuring the character from image 1,
in the visual style of image 2, with the compositional approach
of image 3, showing [new scene description]"
Result: New image guided by multiple reference aspects

Technique 5: Complex Scene Assembly

Building Multi-Layer Compositions

For sophisticated scenes, a single-pass generation often isn't enough. Layer-by-layer construction gives you precise control over every element.

Layer-by-Layer Assembly

Phase 1: Establish Base Scene
- Generate or select background environment
- Ensure proper perspective and lighting
Phase 2: Add Primary Subject
- Place main character or object
- Match to scene lighting and perspective
Phase 3: Add Secondary Elements
- Incorporate supporting objects or characters
- Maintain spatial relationships
Phase 4: Refinement
- Adjust overall composition
- Enhance cohesiveness
- Add final details

Example: Product Launch Scene

Step 1: Generate/Select Background
Prompt: "Modern tech office with large windows, natural daylight"
Step 2: Add Product
Image 1: Background from step 1
Image 2: Product photo
Prompt: "Place the product from image 2 prominently on the
desk in the office from image 1, with natural lighting and reflections"
Step 3: Add Human Element
Image 1: Result from step 2
Image 2: Person photo
Prompt: "Add the person from image 2 sitting at the desk,
interacting with the product naturally"
Step 4: Add Details
Prompt: "Add subtle details: coffee cup, notebook, ambient
office activity in soft focus background"
Result: Comprehensive product lifestyle scene

Atmospheric Enhancement

Base scene established, then:
Prompt: "Enhance this composition by adding [atmospheric elements]:
- Warm golden hour lighting through windows
- Subtle dust particles in light beams
- Soft bokeh in background
- Enhanced color warmth and richness"
Result: Elevated production value and emotional impact

Technique 6: Advanced Character Consistency

Keeping Identity Stable Across Variations

For marketing, narrative, or brand work, character consistency is one of the most commercially important problems to solve. A well-managed reference workflow makes it tractable.

Building a Character Library

Step 1: Establish Base Character
Generate or upload primary character image with detailed description
Step 2: Generate Core Poses
Using reference, create essential poses:
- Neutral standing
- Sitting
- Walking
- Reaching/gesturing
- Close-up portrait
Step 3: Generate Expression Set
Maintain character, vary emotions:
- Happy/smiling
- Surprised
- Thoughtful
- Excited
- Concerned
Step 4: Generate Context Variations
Same character in different settings:
- Professional environment
- Casual home
- Outdoor nature
- Social gathering
- Travel/adventure
Result: Comprehensive character library for any use case

Character with Prop Consistency

Reference Image: Character holding specific object
Prompt: "Using the character and [object] from the reference,
show them [new action/location] while maintaining the exact
appearance of both character and object"
Example: Brand mascot with product across multiple scenarios

Wardrobe Variations

Base Reference: Character in outfit A
Prompt: "Show the same character from the reference image
(same facial features, body type, proportions) but wearing
[different outfit description], in [new setting]"
Use: Seasonal campaigns, different lifestyle contexts

Pro Tips for Multi-Image Work

Tip 1: Image Compatibility

Source images that share similar resolution, compatible lighting directions, harmonious color palettes, and consistent artistic styles will produce significantly cleaner results. Style clashes are only useful when they're intentional.

Tip 2: Descriptive Precision

Vague instructions produce vague results. Instead of:

"Combine these images"

Write:

"Blend these images by placing the subject from image 1 in the foreground of the environment from image 2, matching the golden hour lighting and warm color temperature"

Tip 3: Iterative Refinement

Attempt 1: Broad instruction, see what Nano Banana 2 interprets
Attempt 2: Refine based on results, add specificity
Attempt 3: Fine-tune details, adjust parameters
Attempt 4: Final polish
Don't expect perfection on first try—iterate strategically

Tip 4: Post-Composition Editing

Phase 1: Multi-image composition
Create base composite
Phase 2: Targeted editing
Use Nano Banana 2's editing mode to refine:
- "Adjust the lighting on the subject to be warmer"
- "Soften the transition between foreground and background"
- "Enhance shadows under the placed object"

Tip 5: Build a Reference Library

Maintain reusable assets — approved character references, effective style references, solid background environments, and compositional templates that have worked before. An organized library dramatically reduces setup time on new projects.

Tip 6: Know the Current Limits

Nano Banana 2 can struggle with:

• Highly complex multi-element scenes (5+ discrete elements)
• Precise text rendering inside compositions
• Highly specific technical or mechanical requirements
• Realistic hands in complex poses

Practical workarounds:

• Break complex compositions into fewer-element stages
• Add text overlays in a traditional design tool
• Combine AI generation with manual refinement passes
• Generate multiple variants and select the strongest output

Advanced Prompting for Multi-Image Work

Structural Prompt Framework

[Operation] + [Source Specification] + [Target Specification] +
[Technical Requirements] + [Aesthetic Requirements]

Example:

"Blend [operation] the portrait from image 1 and landscape from image 2
[source specification] by placing the person in the right third of the
scene [target specification], maintaining sharp focus on the subject
with soft bokeh background [technical requirements], in warm golden
hour lighting with rich colors [aesthetic requirements]"

Contextual Prompt Enhancements

Spatial Instructions:

• "in the foreground/background"
• "centered/to the left/right third"
• "occupying 40% of frame height"
• "following rule of thirds"

Lighting Instructions:

• "matching ambient scene lighting"
• "with directional light from upper left"
• "maintaining original subject lighting"
• "adjusting color temperature to match scene"

Atmospheric Instructions:

• "with natural depth of field"
• "maintaining photorealistic quality"
• "with subtle atmospheric haze"
• "sharp throughout" or "with selective focus"

Troubleshooting Multi-Image Compositions

Elements Don't Blend Naturally

Symptoms: Visible seams, mismatched lighting, obvious joins.

Solutions:

• Add "seamlessly" and "naturally" to the prompt
• Explicitly request lighting reconciliation: "adjust subject lighting to match scene"
• Ask for specific integration: "with natural shadow casting"
• Run multiple variants and pick the cleanest result
• Follow up in editing mode to refine problem areas

Incorrect Element Placement

Symptoms: Subject in the wrong position, at the wrong scale, or facing the wrong direction.

Solutions:

• Specify placement precisely: "in the left foreground, approximately 1/3 frame height"
• Reference specific scene landmarks: "sitting at the table visible in the center"
• State perspective requirements explicitly: "matching scene perspective"
• Iterate with progressively more specific instructions

Style Inconsistency

Symptoms: Elements from different sources don't look like they belong together aesthetically.

Solutions:

• Explicitly request visual harmony: "ensuring visual harmony"
• Run a style transfer pass after composition is established
• Use a consistent style reference image across all generation jobs
• Request unified color grading: "with consistent color treatment throughout"

Lost Detail in Complex Compositions

Symptoms: Key details become soft or wash out.

Solutions:

• Reduce the number of elements per generation pass
• Build the scene in stages rather than attempting everything at once
• Request detail preservation explicitly: "with sharp detail preservation"
• Use higher resolution settings
• Refine problem areas with targeted editing prompts

Closing: Compositing as a Workflow

Multi-image composition with Nano Banana 2 puts capabilities in reach that previously required a skilled compositor, a licensed copy of Photoshop, and hours of manual work. The techniques in this guide let you:

• Produce seamless composites from disparate source images
• Assemble complex scenes from individually simple elements
• Hold character and brand identity stable across large image series
• Apply sophisticated visual styles without manual brush work
• Reach professional-quality output in minutes, not hours

A few principles that separate consistent results from inconsistent ones:

• Start simple. Nail basic blending before attempting five-element assemblies.
• Describe constraints, not just changes. Specify what must stay the same as clearly as what should change.
• Iterate with intention. Use each result to refine the next prompt rather than regenerating from scratch.
• Build reusable references. A library of approved character, style, and environment references pays compounding dividends.
• Combine techniques. The most sophisticated outputs layer multiple approaches — reference-based generation on top of element extraction on top of style transfer.
• Treat each pass as information. Unexpected outputs reveal what the model understood; use that to write a sharper next prompt.

The gap between a single AI-generated image and a production-ready visual asset is almost always a composition strategy problem, not a model capability problem. The techniques here close that gap.
