Advanced Prompt Engineering
The Art of Descriptive Precision
Rule #1: Specificity Beats Ambiguity
❌ Poor: "Make this photo look better"
✅ Excellent: "Enhance this portrait with soft, natural lighting from the left, remove skin blemishes while maintaining natural texture, and adjust the background to a subtle warm grey gradient"
Rule #2: Layer Your Instructions
Instead of one complex sentence, break down your vision into digestible components:
Primary action: "Replace the background with a modern office setting"
Lighting instruction: "Ensure the lighting on the person matches the office environment"
Quality specification: "Maintain professional photography quality with sharp focus"
Style preference: "Corporate but approachable atmosphere"
For Image Generation
Formula: [Subject] + [Action/Pose] + [Setting] + [Lighting] + [Style] + [Quality modifiers]
Example: "A professional businesswoman presenting to a team in a modern conference room with natural window lighting, corporate photography style, sharp focus, high resolution"
For Image Editing
Formula: [Preservation instruction] + [Change description] + [Style specification] + [Quality requirements]
Example: "Keep the person's face and expression exactly the same, change their casual clothes to a formal navy business suit, ensure professional lighting consistency, maintain photorealistic quality"
For Multi-Image Fusion
Formula: [Source identification] + [Transfer instruction] + [Integration specification] + [Harmony requirements]
Example: "Take the elegant evening dress from image 1 and place it on the model from image 2, adjust the lighting to match the formal setting, ensure natural fabric flow and realistic proportions"
Image Quality Optimization
Resolution and Quality Standards
Optimal Input Specifications:
- Resolution: Minimum 1024x1024 pixels for best results

- File Size: Use maximum allowed for your plan (5MB-20MB depending on subscription)
- Format: PNG for images with transparency, JPEG for regular photos
- Compression: Minimal compression for best AI analysis
Lighting Optimization
Pre-Upload Checklist:
- ✅ Even lighting without harsh shadows
- ✅ Clear subject definition
- ✅ Minimal noise or grain
- ✅ Good contrast between subject and background
- ✅ Avoid extreme backlighting or silhouettes
Post-Processing Integration

Mode-Specific Professional Techniques
Image Generation Mastery
Environmental Context Building
Technique: Create rich, layered environments by describing multiple sensory elements
Amateur Approach: "A person in an office"
Professional Approach: "A confident professional in a contemporary glass-walled office with natural daylight streaming through floor-to-ceiling windows, modern ergonomic furniture, subtle greenery, and a city skyline visible in the background, captured with professional corporate photography techniques"
Style Consistency Techniques
For Brand Work:
- Create a style sheet: Document your preferred lighting, color palette, and composition rules
- Use consistent descriptors: Develop a vocabulary of terms that reliably produce your desired aesthetic
- Build template prompts: Create reusable prompt structures for different content types
Image Editing Excellence
Character Preservation Strategies
Nano Banana's character consistency is powerful, but you can enhance it:
Best Practices:
- Face-forward source images: Better facial recognition and preservation
- Clear feature definition: Ensure eyes, nose, and mouth are clearly visible
- Consistent lighting on face: Even facial lighting in source images
- Multiple reference angles: Use different angles for complex transformations
Background Replacement Mastery
Professional Technique - The Three-Layer Approach:
- Layer 1 - Environment: "Place subject in [specific environment]"
- Layer 2 - Lighting: "Match lighting to be consistent with [lighting description]"
- Layer 3 - Integration: "Ensure natural shadows and reflections appropriate for the environment"
Example Application:
Layer 1: "Place this person in a luxury hotel lobby"
Layer 2: "with warm, elegant ambient lighting from crystal chandeliers"
Layer 3: "including subtle shadows on the marble floor and natural light interaction"
Multi-Image Fusion Expertise
The Sequential Fusion Method
For complex multi-image projects:
Step 1: Identify your "anchor image" (primary composition)
Step 2: List specific elements to transfer from other images
Step 3: Plan the integration order (backgrounds first, then subjects, then details)
Step 4: Specify harmony requirements for each element
Color Harmony in Fusion
Professional Tip: Always include color temperature instructions
❌ Without color harmony: "Combine these two images"
✅ With color harmony: "Combine these images while ensuring consistent color temperature and lighting that creates a cohesive, naturally-lit scene"
Advanced Workflow Optimization
Batch Processing Strategies
Template-Based Approach
For Consistent Brand Content:
- Create master prompts for different content types
- Use placeholder variables: [PERSON], [SETTING], [PRODUCT]
- Systematically replace variables for each use case
- Maintain a prompt library for quick access
Example Template:
Master Prompt: "Professional headshot of [PERSON] in [SETTING] with [LIGHTING_STYLE], corporate photography quality, [COLOR_SCHEME] color palette"
Variations:
- CEO announcement: [PERSON=executive], [SETTING=modern office], [LIGHTING_STYLE=confident directional], [COLOR_SCHEME=cool professional]
- Team introduction: [PERSON=team member], [SETTING=collaborative workspace], [LIGHTING_STYLE=warm approachable], [COLOR_SCHEME=warm welcoming]
Quality Control Workflow
The Three-Pass System
Pass 1 - Technical Review: Check resolution, clarity, and technical accuracy
Pass 2 - Aesthetic Review: Evaluate composition, color harmony, and visual appeal
Pass 3 - Brand/Purpose Alignment: Ensure the result meets your specific objectives
Iteration Strategy
Smart Iteration Process:
- Identify specific issues: Don't re-do everything, target specific problems
- Isolate variables: Change one element at a time to understand cause and effect
- Document successful approaches: Build your personal "what works" database
Common Mistakes and Solutions
Prompt Writing Pitfalls
Mistake #1: Conflicting Instructions
❌ Problem: "Make it bright and moody"
✅ Solution: "Create dramatic lighting with bright highlights and deep shadows for a cinematic mood"
Mistake #2: Vague Quality Descriptors
❌ Problem: "Make it look good"
✅ Solution: "Ensure sharp focus, natural colors, professional lighting, and high dynamic range"
Mistake #3: Ignoring Physical Laws
❌ Problem: "Put this person underwater but keep their hair dry"
✅ Solution: Consider realistic physics in your requests
Technical Issues and Fixes
Problem: Inconsistent Character Features
Symptoms: Facial features slightly changing between edits
Solutions:
- Use higher resolution source images
- Ensure face is well-lit and clearly visible
- Avoid extreme angles in source photos
- Be explicit about feature preservation: "maintain exact facial features and bone structure"
Problem: Unnatural Lighting Transitions
Symptoms: Subject looks "pasted" into new environments
Solutions:
- Always specify lighting integration: "adjust lighting on subject to match environment"
- Describe shadow requirements: "include natural shadows consistent with lighting direction"
- Consider reflective surfaces: "ensure appropriate reflections if in glossy environment"
Problem: Style Inconsistencies
Symptoms: Mixed artistic styles within single image
Solutions:
- Be consistent with style descriptors throughout your prompt
- Use reference style terms: "maintain photorealistic style throughout"
- Avoid mixing artistic periods: Don't combine "Renaissance painting" with "modern photography"
Credit Efficiency Strategies
Maximizing Your Investment
Smart Testing Approach
- Start simple: Test concepts with basic prompts first
- Refine gradually: Add complexity only after confirming the basic approach works
- Document successful prompts: Build a library of proven approaches for different scenarios
Prompt Refinement Before Processing
