Cinematic Variation
Cinematic night scene with neon city reflections. Keep the same person, pose, and composition. Add dramatic lighting with cyan and magenta tones. Wet street reflections, bokeh lights in background. No text.
Background Swap
CRITICAL: Keep the subject EXACTLY the same (face identity, hair, skin tone, expression, body proportions, pose/walking posture, clothing, bag, and camera framing). Do not change the subject at all. ONLY CHANGE: Replace the background with a sunny beach boardwalk scene: wooden boardwalk leading into the distance, palm trees, bright blue sky, ocean visible, warm natural sunlight. LIGHTING MATCH: Ensure the subject lighting matches the beach scene (same sun direction, color temperature, and shadow strength). Add a subtle natural ground shadow consistent with the boardwalk. EDGE BLENDING: Clean, realistic edges around hair and clothing (no cutout look, no halos). Keep fine hair strands. DEPTH: Match depth-of-field so subject and background feel like the same photo (consistent blur and perspective). No text, no watermark, no extra people added.
Outfit Change
CRITICAL: Keep the subject EXACTLY the same (face identity, hair, skin tone, expression, body proportions, pose, and camera framing). Keep the background EXACTLY the same (same beach boardwalk, palm trees, sky, ocean). Keep the bag EXACTLY the same. ONLY CHANGE: Replace the clothing with a quiet luxury "old money" outfit: camel structured coat, cream premium knit sweater, navy tailored trousers. Elegant and minimal. No new accessories added. Photorealistic fabric texture with natural folds. Seamless transitions at neckline, sleeves, and waist. Match the original daylight direction and shadow softness. No text, no watermark.
Product White BG
CRITICAL: Keep the product EXACTLY the same (shape, design, color, materials, laces, stitching). Do NOT change the sneaker design in any way. ONLY CHANGE: Remove the background completely and place the product on a pure white seamless studio background (#FFFFFF). No text, no watermark.

Image-to-image vs image editing
Both features are available in Nano Banana, but they serve different purposes.
Use Editing For:
- Precise changes: remove a specific object
- E-commerce: pure white backgrounds
- Corrections: fix lighting, remove blemishes
- When subject must stay exactly identical
Use Image-to-Image For:
- Creative variations: different styles, moods
- Dramatic transformations: cinematic looks
- Exploring options: multiple variations
- When you want AI to be more creative

Frequently Asked Questions
Quick answers to common questions about Nano Banana image-to-image
Image-to-image (img2img) uses your uploaded photo as a starting point to generate new variations. Unlike text-to-image which creates from nothing, img2img preserves elements you specify while transforming others — style changes, mood shifts, background replacement, and more.
Image editing makes precise, controlled changes (remove object, exact background color). Image-to-image creates artistic variations and transformations. Use editing when you need exact control; use img2img when you want creative exploration. Both are available in Nano Banana.
Include explicit constraints in your prompt: 'keep the same person exactly', 'preserve identity and pose', 'maintain original composition'. The more specific you are about what should stay the same, the better. For portraits, also add 'no face changes' and 'natural skin texture'. Use fewer constraints for more creative freedom.
Use clear, well-lit images with the subject prominently visible. Resolution of 1024x1024 or higher works best. Avoid heavily compressed images, blurry photos, or obscured details. Quality in means quality out.
Most transformations complete in 2-5 seconds using Gemini 2.5 Flash Image (Nano Banana). Complex variations may take slightly longer.
