TL;DR
What did u/rurbornse use Gemini for?
Someone took a portrait of their dog in the back seat of a car and asked Nano Banana Pro in Gemini to remove the leash and give it a festive Halloween background, while keeping the dog's face, markings, expression and bandana. A commenter said the background swap looked far better than earlier models and the dog looked like it belonged there.
What they did
They uploaded the photo and used one prompt: remove the leash across his body, create a more festive Halloween background than the car backseat, keep his orange Halloween bandana, and keep the same face, markings and expression. Spelling out what must stay the same is what they credit for avoiding unwanted changes.
How it went
A commenter said the background swap looked far better than earlier models and the dog looked like it belonged there.
Worth knowing
- They ran it through an image editor they are building on top of the model, with strict rules about what it may change, so results in the plain Gemini app may vary. They recommend keeping a reusable cheat sheet of 'keep the same' rules.
- Price check: Google Gemini: free plan; Google AI Plus: US$4.99/month (checked Nov 1, 2026).
