Practice with your own photo using this exact prompt structure. Start simple, then experiment with more complex edits.
Writing Effective Prompts
The key to amazing results lies in how you communicate with the AI. Here's your guide to prompt mastery.
❌ Avoid These Prompts
"Make it better"Too vague - AI doesn't know what "better" means
"Change everything"Too broad - likely to lose important details
"Add some colors"Unclear - which colors? Where?
✅ Use These Instead
"Replace the plain background with a vibrant sunset over mountains, keeping the person's pose and clothing identical"Specific and clear about changes and preservation
"Change only the shirt color to deep navy blue, maintain everything else exactly as is"Precise targeting of single element
"Add warm golden hour lighting from the left side, preserving all facial features and expressions"Detailed lighting instruction with preservation note
The Perfect Prompt Formula
Example: "Transform the background into a cozy coffee shop interior with warm lighting and vintage decor, while keeping the person's expression and clothing exactly the same"
Professional Tips & Best Practices
1Start with High-Quality Images
Use images with good resolution (at least 1024px), proper lighting, and clear subjects. The AI works best with quality source material.
2Make Gradual Changes
Instead of dramatic transformations, make small, incremental edits. This maintains consistency and gives you more control.
3Use Reference Images
When possible, provide multiple reference images for context. This helps the AI understand your vision more accurately.
4Iterate and Refine
Don't expect perfection on the first try. Use multi-turn editing to refine specific aspects until you achieve your desired result.
5Save Your Progress
Download intermediate results before making additional changes. This gives you fallback options if later edits don't work out.
6Experiment with Styles
Try different artistic styles, lighting conditions, and moods. Nano Banana excels at style transfer while maintaining subject integrity.
Avoiding Common Beginner Mistakes
🚫 Mistake #1: Overcomplicating First Attempts
New users often try complex, multi-element changes in their first edit, leading to unpredictable results.
Solution: Start with single-element changes like background replacement or color adjustments before attempting complex transformations.
🚫 Mistake #2: Ignoring Image Composition
Using poorly composed or low-quality source images limits the AI's ability to produce professional results.
Solution: Choose images with good lighting, clear subjects, and proper framing. The AI enhances good photos—it can't fix fundamental composition issues.
🚫 Mistake #3: Not Specifying Preservation
Forgetting to specify what should remain unchanged often results in unwanted alterations to important elements.
Solution: Always include preservation instructions: "keep the person's face and expression exactly the same" or "maintain all facial features."
