Mastering AI Image Editing: The Ultimate Guide to Writing Effective Prompts

The difference between amateur and professional results with Nano Banana's AI image editing often comes down to one crucial skill: writing effective prompts. Whether you're using our image generation, editing, or multi-image fusion features, the right prompt can mean the difference between mediocre results and stunning, professional-quality images.

Understanding Nano Banana's Three Modes

Before diving into specific techniques, let's understand how prompts work differently across Nano Banana's three powerful modes:

🎨 Image Generation (1 Credit)

Purpose: Create entirely new images from text descriptions Prompt Focus: Detailed scene description, style specifications, quality requirements

✂️ Image Editing (1 Credit)

Purpose: Modify existing images while preserving character consistency
Prompt Focus: Specific changes, preservation instructions, integration requirements

🔀 Multi-Image Fusion (2 Credits)

Purpose: Combine elements from multiple images seamlessly Prompt Focus: Element identification, integration instructions, harmony specifications

The Anatomy of a Perfect Prompt

Essential Components

Every effective Nano Banana prompt should include:

1. Primary Action: What you want to accomplish
2. Preservation Instructions: What to keep unchanged (especially for editing)
3. Quality Specifications: Technical and aesthetic requirements
4. Style Guidelines: Visual style and mood
5. Integration Details: How elements should work together

The SPACE Framework

Use this proven framework for consistent results:

• Subject: Who or what is the main focus
• Preservation: What must remain unchanged
• Action: What changes or creations you want
• Context: Setting, environment, or background
• Enhancement: Quality, style, and refinement details

Image Generation Mastery

Professional Prompt Structure

[Subject Description] + [Setting/Environment] + [Lighting] + [Style] + [Quality Modifiers]

Excellent Examples

❌ Poor: "A business person" ✅ Professional: "A confident business executive in a modern glass office, natural window lighting creating soft shadows, corporate photography style, sharp focus, professional quality"

❌ Poor: "Make a landscape" ✅ Professional: "A serene mountain landscape at golden hour with crystal-clear lake reflections, snow-capped peaks in the background, warm natural lighting, fine art photography style, high resolution"

Industry-Specific Templates

Corporate/Business:

"Professional [role] in [setting], wearing [attire], [lighting type], corporate photography style, executive portrait quality, [mood/expression]"

Creative/Artistic:

"[Subject] in [artistic style], [color palette], [mood/atmosphere], [artistic movement inspiration], gallery-quality, [specific artistic techniques]"

Image Editing Excellence

The Three-Layer Approach

For complex edits, structure your prompts in layers:

1. Preservation Layer: What must stay identical
2. Change Layer: What needs to be modified
3. Integration Layer: How changes should blend naturally

Master Templates

Character Preservation Template:

"Maintain the person's exact facial features, expression, and bone structure while [specific changes]. Ensure [integration requirements] and [quality specifications]."

Professional Example:

"Keep this person's face, expression, and posture exactly the same while changing their casual clothes to a navy business suit with crisp white shirt. Ensure professional corporate lighting and executive-level presentation quality."

Background Replacement Mastery

❌ Weak: "Change the background" ✅ Strong: "Replace the background with a modern office environment while maintaining the same lighting direction on the subject, ensuring natural shadows and environmental reflections appropriate for an indoor corporate setting"

Style Transfer Techniques

"Convert this image to [artistic style] while preserving all facial features and character identity. Maintain [specific elements] and ensure [quality requirements]."

Example:

"Transform this portrait into an oil painting style while keeping the person's exact facial features, expression, and eye color identical. Use warm, classical color palette with professional artistic quality."

Multi-Image Fusion Secrets

The Sequential Method

For complex fusion projects:

"Take [specific element] from image [number] and [action] with [target element] from image [number], ensuring [harmony requirements] and [quality specifications]."

Professional Fusion Template

"Integrate the [clothing/object/element] from image 1 onto the [subject] in image 2, ensuring:
- Natural fit and proportions appropriate for the subject
- Lighting consistency across all elements  
- Realistic shadows and fabric behavior
- Professional photography quality
- [specific style or mood requirements]"

Advanced Fusion Techniques

Character Consistency Across Images:

"Take the hairstyle from image 1 and apply it to the person in image 2, maintaining their exact facial features while ensuring the new hairstyle looks natural with their face shape and lighting environment."

Environmental Integration:

"Place the subject from image 1 into the background environment from image 2, adjusting lighting on the subject to match the environmental lighting direction and color temperature, with appropriate shadows for the new setting."

Advanced Prompting Techniques

Lighting Mastery

Always specify lighting when it matters:

• Direction: "lighting from the left", "front-lit", "natural window light"
• Quality: "soft diffused", "dramatic directional", "even studio lighting"
• Color: "warm golden hour", "cool daylight", "warm tungsten"
• Mood: "professional corporate", "creative and artistic", "natural and approachable"

Quality Specifications

Include technical requirements:

• Resolution: "high resolution", "professional quality", "sharp focus"
• Style: "corporate photography", "artistic portrait", "commercial product shot"
• Processing: "natural colors", "enhanced contrast", "professional retouching"

Common Mistakes to Avoid

❌ Conflicting Instructions: "bright and moody" (contradictory) ✅ Clear Direction: "dramatically lit with bright highlights and deep shadows"

❌ Vague Quality Terms: "make it look good" ✅ Specific Requirements: "professional photography quality with sharp focus and natural colors"

❌ Ignoring Physics: "underwater but keep hair dry" ✅ Realistic Requests: "underwater scene with natural hair and clothing movement"
