Image Editing with Google Nano Banana

Note: Since this guide was written, Nano Banana has expanded into a model family (Nano Banana 2, Nano Banana Pro, Nano Banana 2 Lite) — see Google's official announcement. Google describes Nano Banana 2 as able to "maintain character resemblance of up to five characters and the fidelity of up to 14 objects in a single workflow," supporting resolutions from 512px to 4K. The core editing workflow below still applies.

Whether you’re restoring an old photo, adjusting lighting, or creating complex multi-turn edits, Nano Banana combines speed, fidelity, and world knowledge to deliver results that feel both natural and precise.

✨ Core Editing Features

1. Local & Global Edits

• Make changes to a specific part of an image or transform the entire scene.
• Works seamlessly across small tweaks and large-scale transformations.

Example Prompts:

• “Remove the person standing in the background.”
• “Change this photo of the park from daytime to sunset.”

2. Multi-Turn Conversational Editing

• Unlike traditional “one-shot” systems, Nano Banana allows step-by-step refinements.
• Each step builds naturally on the previous edit without breaking image consistency.

Example Workflow:

• Prompt 1: “Make this a sunset.”
• Prompt 2: “Add lanterns along the path.”
• Prompt 3: “Put fireworks in the background.”

3. Recoloring & Restoration

• Photo restoration: Repair scratches, sharpen blurry details, and colorize black-and-white images.
• Creative recoloring: Change clothing colors, product finishes, or entire palettes with realistic lighting and textures.

Example Prompts:

• “Restore this old photo: remove scratches and sharpen the details.”
• “Recolor this black-and-white wedding photo into natural colors.”
• “Change the sofa color from beige to emerald green.”

4. Object Addition & Removal

• Insert new elements into a photo with context-aware realism.
• Cleanly erase unwanted objects while preserving background detail.

Example Prompts:

• “Add a coffee cup on the desk next to the laptop.”
• “Remove the street sign on the left side of the photo.”

5. Pose & Layout Adjustments

• Modify human or object poses while keeping proportions natural.
• Works with structured compositions like product catalogs, ID cards, or fashion lookbooks.

Example Prompts:

• “Adjust the person’s pose so they are sitting cross-legged instead of standing.”
• “Rearrange the objects on the table into a neat grid layout.”

6. Lighting & Atmosphere Control

• Change weather, time of day, or mood with natural results.

Example Prompts:

• “Turn this summer scene into a snowy evening with warm lights inside the house.”
• “Make this photo look like a cinematic scene with dramatic shadows.”

🎨 Identity & Style Stability

Nano Banana preserves faces, pets, and brand visuals across edits.

Example Prompts:

• “Keep the same person’s face consistent while changing their outfit into a medieval knight’s armor.”
• “Apply a watercolor style filter but preserve the character’s identity.”

🛠️ Practical Use Cases

E-Commerce:

• “Generate a winter holiday version of this shoe catalog photo.”

Architecture:

• “Replace the brick exterior of this house with modern glass panels.”

Fashion:

• “Recolor this dress into silk red fabric.”

Heritage Projects:

• “Restore this faded family portrait and colorize it naturally.”

Marketing:

• “Create three ad banner variations: tropical theme, winter theme, and minimalist black-and-white.”

‍

🔒 Responsible Editing

• All edited images include SynthID watermarking.
• Guardrails prevent harmful or deceptive manipulations.

Example Prompt:

• “Add branding text to this photo with a visible watermark in the corner.”

📂 Example: Step-by-Step Edit

Original Prompt:

• “Take this portrait photo. Change background to a sunset beach.”

Follow-up Edits:

1. “Add string lights behind the subject.”
2. “Recolor the dress to deep blue velvet.”
3. “Soften the lighting for a cinematic feel.”

Result:
A natural-looking sequence of edits where the subject’s identity is preserved, and each request builds logically on the last.

👉 With Nano Banana, image editing feels like a conversation — intuitive, precise, and endlessly creative.
