The Journey of a "Human Editor"
Hi dev.to! I’m the developer of Nano Banana Editor.
Before building this, I spent months manually helping people in subreddits like r/PhotoShopRequest. I’ve processed over 100 complex photos for free to understand one thing: What makes a perfect AI removal?
Most tools fail because they just "erase." I wanted a tool that "reconstructs."
The "Magic" Prompt: My Secret Sauce 🛠️
After testing hundreds of iterations, I discovered that the secret to a clean background isn't just the model—it’s the prompt logic. Here is the "Golden Prompt" I developed, which handles about 90% of my requests:
The Base Prompt:
"Remove all the tourists/people in the background behind the main subject. Intelligent Fill: Replace them with realistic background elements that logically fit the scene (e.g., extend the cobblestone pavement, empty park benches, or grass textures). Consistency: Ensure no blurry artifacts or 'smudges' remain. The filled area must have the same grain, focus depth, and lighting as the rest of the photo."
Of course, AI isn't magic. For specific cases (like removing a person to the right of a girl in a white dress while keeping her pose intact), I found that minor tweaks to this core prompt are the key to success.
The Logic: Nano Banana vs. Nano Banana Pro
In my tool, Nano Banana Editor, I’ve implemented a two-tier system:
- Nano Banana: Great for standard cleanup and fast iterations.
- Nano Banana Pro: For complex textures and high-stakes shots. It’s "smarter" and understands spatial relationships much better.
Let's Talk About "The Gacha" (The Iteration) 🎲
As developers, we know that AI image generation is still a bit of a "gacha" (random draw). Sometimes you get it on the first try; sometimes you need three.
But here’s what I learned after 100+ manual tests: With the right prompt foundation, you don't need to "draw" many times. Usually, 2-3 tweaks to the prompt or switching to the Pro model gets the job done.
My UI is designed around this—upload a photo, run the optimized prompt, and if the result isn't 100%, a quick tweak or a model upgrade usually delivers the final masterpiece.
🖼️ Real-World Performance
Remove Person Prompt:
`Remove the tourists/people on the left and right sides of the image of the girl in the pink down jacket, keeping only the one in the middle. The girl's hand gesture in the background remains unchanged.
Smart Fill: Replace them with realistic background elements that fit the scene's logic.
Consistency: Ensure there are no blurry imperfections or smudges. The filled area must have the same grain, depth of focus, and lighting as the rest of the photo.`
I won't add any more examples. If you want me to remove people from your photos, just upload the images directly, and I'll process them for you and give you the desired results.
Why I built this specifically
Photoshop is a beast, but it’s overkill for most people. I wanted to build a page where:
- You upload a photo.
- You use an expert-level, pre-tuned prompt (with room to tweak).
- You get a professional result without the 3-year learning curve.

I'm looking for "Challenge" Photos! 🤝
I want to see where my "Golden Prompt" fails. Drop your messiest, most crowded photos in the comments!
- I will manually tweak the prompt to fix it for you.
- I’ll use your case to refine the default logic on the site.
Dev.to Special: If you find a specific prompt tweak that works better than mine, let me know! I’ll credit your account with extra credits for the contribution.
