Nano Banana is a powerful AI image generation tool that leverages advanced AI models to transform your text descriptions into high-quality images. This guide will help you master Nano Banana's capabilities by teaching you how to write prompts that consistently deliver professional, creative, and precisely controlled results.

Ground Rules for Effective Prompts

Before diving into templates, let's establish the core principles:

• Be extremely specific: Replace generic words with detailed descriptions
• Provide context: Explain the purpose and mood of your image
• Use semantic guidance: Describe what you want, not what you don't want
• Control composition: Use photography and cinematography language
• Iterate and refine: Start simple, then add layers of detail

Universal Prompt Template

Subject: [main focus with specific details]
Style: [artistic style, medium, or aesthetic]
Composition: [shot type, angle, framing]
Lighting: [light direction, quality, mood]
Environment: [setting, background, atmosphere]
Details: [textures, colors, materials, mood]
Technical: [resolution hints like "high-resolution", "studio-lit"]

Example: Product Photography

Generic prompt:

A bottle of perfume

Optimized prompt:

A high-resolution, studio-lit product photograph of an elegant glass perfume bottle
with rose gold accents, positioned on a marble surface. Soft diffused lighting from
the left creates subtle highlights on the glass surface. Minimalist composition with
a clean white background and shallow depth of field. Professional commercial style.

Example: Artistic Illustration

Generic prompt:

A fantasy character

Optimized prompt:

A detailed character illustration of an elven warrior wearing elaborate silver plate
armor with leaf etchings, standing in an ancient forest. Digital art style with
vibrant colors and dramatic side lighting. Medium shot from a slightly low angle,
with soft focus on the misty background. Rich emerald greens and silver tones.

Style-Specific Templates

Photorealistic Images

A [shot type] photograph of [subject] [action/pose], set in [environment].
[Lighting description] creates [mood]. Shot on [camera/lens details] with
[depth of field]. [Color grading/atmosphere]. High-resolution, professional quality.

Example:

A wide-angle photograph of a cozy coffee shop interior at golden hour, with warm
sunlight streaming through large windows. A barista pours latte art in the foreground.
Soft natural lighting creates an inviting atmosphere. Shot with a 35mm lens with
shallow depth of field, background slightly blurred. Warm color grading with rich
browns and golden tones. High-resolution, magazine-quality.

Stylized Illustration

A [style] illustration of [subject], featuring [key characteristics].
[Composition details]. Color palette of [colors]. [Mood/atmosphere].
[Additional style notes].

Example:

A minimalist vector illustration of a modern workspace, featuring a laptop,
coffee cup, and plant on a clean desk. Flat design with simple shapes and
clean lines. Color palette of soft pastels - mint green, coral pink, and
cream white. Calm and organized atmosphere. Suitable for tech blog header.

Logo & Brand Design

Logo design for [brand name], a [industry/type] brand focused on [values/target].
[Style description] with [key visual elements]. [Color scheme]. [Mood/feeling].
Clean, scalable, memorable.

Example:

Logo design for "GreenLeaf Organics", a high-end minimalist skincare brand
focused on natural ingredients and sustainability. Modern sans-serif typography
combined with an elegant leaf icon. Color scheme of deep forest green and
soft cream. Sophisticated, trustworthy, eco-conscious. Clean, scalable, memorable.

Composition Control Techniques

Use these cinematic and photographic terms to control how your image is framed:

Shot Types

• Wide shot / establishing shot: Shows full scene and environment
• Medium shot: Subject from waist up
• Close-up: Face or object detail
• Macro shot: Extreme close-up showing fine details
• Overhead / top-down: Bird's eye view

Camera Angles

• Eye level: Natural, neutral perspective
• Low angle: Camera looking up (makes subject look powerful)
• High angle: Camera looking down (makes subject look vulnerable)
• Dutch angle / tilted: Creates dynamic tension

Composition Rules

• Rule of thirds: Subject positioned at intersecting lines
• Center composition: Subject in dead center (formal, symmetrical)
• Leading lines: Lines that guide eye to subject
• Negative space: Empty space around subject
• Foreground elements: Objects in front add depth

Lighting Vocabulary

Lighting dramatically affects mood and quality:

• Soft diffused lighting: Gentle, even light (flattering, peaceful)
• Dramatic side lighting: Strong light from one side (creates depth)
• Backlight / rim light: Light behind subject (creates silhouette or glow)
• Golden hour: Warm, soft sunlight (romantic, nostalgic)
• Studio lighting: Professional, controlled (clean, commercial)
• Volumetric lighting: Visible light beams (atmospheric, dramatic)
• Neon lighting: Colored artificial light (modern, cyberpunk)

Common Mistakes to Avoid

❌ Don't:

• Use negative language ("no cars", "without people")
• Mix contradictory styles ("photorealistic anime")
• Overload with too many concepts in one prompt
• Use vague words like "nice", "good", "beautiful"

✅ Do:

• Describe the desired scene actively ("empty street", "solitary figure")
• Commit to one cohesive style per image
• Focus on one main subject per generation
• Use specific, descriptive language

Iterative Refinement Strategy

Professional results come from iteration:

1. Start simple: Basic subject and style (10-15 words)
2. Review output: Identify what's working and what's not
3. Add details incrementally: Layer in composition, lighting, mood
4. Use conversational refinement: "Make the lighting warmer", "Add more detail to the background"
5. Lock in winners: Save effective prompt patterns for reuse

Example Iteration

Round 1:

A modern living room with plants

Round 2 (after seeing results):

A modern Scandinavian living room with large windows, multiple indoor plants,
and minimalist furniture. Natural lighting.

Round 3 (final refinement):

A modern Scandinavian living room with floor-to-ceiling windows, abundant indoor
plants including monstera and fiddle leaf fig, minimalist oak furniture, and a
neutral color palette. Soft natural lighting from the left creates a calm atmosphere.
Wide-angle shot showing the full space. High-resolution, magazine-quality interior
photography.
