Nano Banana 2 Prompt Guide
Master AI image generation and editing with Nano Banana 2. Write effective prompts for photorealistic images, text rendering, character consistency, and creative editing.
Pro Tip
Stop using "tag soups" (e.g., dog, park, 4k, realistic). Nano Banana 2 understands natural language — describe your image like a Creative Director giving a brief. The more conversational and specific you are, the better the results.
Part 1: The Prompt Formula
A great Nano Banana 2 prompt follows this structure: [Subject] + [Action/Pose] + [Scene] + [Style] + [Details]
1. Subject — Who or What
Be specific about the main subject. Avoid vague terms — describe exactly what you see.
Bad:
"A woman in a red dress"
Good:
"A young woman in her mid-20s with dark curly hair, wearing a flowing crimson silk dress with a deep V-neckline, gold hoop earrings"
2. Scene & Environment
Set the stage — describe the background, lighting, and atmosphere.
Example:
"Standing on a cobblestone street in Paris at golden hour, with the Eiffel Tower softly blurred in the background. Warm sunlight casting long shadows, vintage Parisian cafe visible to the left"
3. Style & Composition
Define the visual style, camera angle, and artistic direction.
- Photography: "shot on 35mm film", "Canon EOS R5", "shallow depth of field", "f/1.4 bokeh"
- Art styles: "oil painting", "watercolor", "digital illustration", "anime style"
- Composition: "wide-angle shot", "close-up portrait", "bird's-eye view", "rule of thirds"
- Lighting: "rim lighting", "studio lighting", "neon glow", "dramatic chiaroscuro"
Part 2: Text Rendering
Nano Banana 2 excels at generating clean, accurate text within images — ideal for marketing mockups, social media graphics, posters, and branded content.
Template
"Create a [image type] for [brand/concept] with the text '[your text]' in a [font style]. The design should be [style], with a [color scheme]."
Examples
Poster
"A minimalist movie poster with the title 'MIDNIGHT SUN' in bold sans-serif typography at the top. A lone astronaut silhouette stands against a massive orange sun on a dark horizon. Tagline at the bottom: 'Some journeys have no return.'"
Social Media
"An Instagram story graphic with the text 'SALE 50% OFF' in large white brush script. Background: trendy gradient from coral pink to warm orange. Small text at the bottom: 'Limited time only' in clean sans-serif."
Greeting Card
"A birthday card with 'Happy Birthday!' in playful hand-lettered script. Surrounded by watercolor flowers in soft pastel colors. Below: 'Wishing you a wonderful day' in elegant serif font."
Translation tip: Nano Banana 2 can translate and localize text within images. Try: "Create a cafe menu in both English and Japanese, with the Japanese text in a traditional calligraphy style."
Part 3: Character Consistency
Maintain character resemblance for up to 5 characters and fidelity for up to 14 objects — perfect for comics, brand campaigns, and sequential storytelling.
Step 1: Build a Character Sheet
Generate 2-3 reference images of your character from different angles.
"A character reference sheet of a young woman named Aria: short platinum bob haircut, bright green eyes, freckles across her nose, wearing a dark blue leather jacket over a white t-shirt. Show front view, side profile, and three-quarter view."
Step 2: Use References in New Scenes
Upload the character sheet as a reference image and describe the new scene.
"Place this exact character in a rainy Tokyo street at night, maintaining identical features. She's holding a transparent umbrella, neon signs reflecting in puddles around her."
Step 3: Iterate, Don't Restart
If the result is 80% correct, describe the specific change you need.
"Using this image, make her look slightly to the left and add a subtle smile. Keep everything else the same."
Part 4: Image Editing
Upload any image and describe your changes in natural language. Nano Banana 2 handles it all.
Object Addition
"Add a golden retriever sitting next to the person on the bench."
Object Removal
"Remove the person standing in the background and fill in the scene naturally."
Background Swap
"Replace the background with a sunset beach scene, keep the subject and lighting consistent."
Style Transfer
"Transform this photo into a Studio Ghibli anime style illustration while preserving the composition."
Detail Enhancement
"Enhance the image details and clarity, make the colors more vibrant and the textures sharper."
Creative Transform
"Turn this photo into a 3D figurine, complete with a display box and packaging."
