Gemini Nano Banana Prompts: Photo Edits, Retro Looks and Festive Portraits
6 min read · Updated 09 Nov 2026 · By the Picslot team
Nano Banana is the popular nickname for Google's Gemini image model, which became famous for editing a photo with a plain sentence. Edit prompts work differently from text-to-image prompts: you describe what to keep and what to change.
Write edit prompts: keep and change
A good edit prompt has two parts. First what must stay the same, then the change: "keep the face and pose unchanged; change the background to a sunlit garden and the outfit to a green jacket".
Make one main change at a time. Ask for follow-up changes after you see the result.
Retro film and Polaroid looks
Retro edits are easy to describe: "add a warm 35mm film look with soft grain and faded colours" or "make it look like an instant Polaroid snapshot with a white border".
These trends are popular because they feel nostalgic. Keep the wording short and name the era if it matters, such as "1990s".
Festive and traditional portrait ideas
Many people create festive portraits for occasions such as Diwali, Durga Puja or weddings: "warm diya light, silk saree in deep red with gold border, marigold garlands, soft evening glow, natural expression". Describe clothing and setting with care and respect for the culture.
Use only photos of yourself or people who agreed, and avoid anything that could mislead others about a real person.
Tips for consistent results
Use a clear, well-lit reference photo, keep the request specific, and repeat the key detail you care about (for example the hairstyle) in each follow-up.
You can try similar edits in our AI image generator with up to 3 reference photos, and browse community ideas on the Nano Banana prompts page.
