Nano Banana, powered by Google's Gemini 2.5 Flash, is one of the fastest and most capable AI image generation models available in Cubby Image. In this guide, we'll show you how to get the most out of it.

What is Nano Banana?​

Nano Banana is an AI model that uses Google's Gemini 2.5 Flash technology to generate high-quality images from text prompts. It's known for:

  • ⚡️ Speed: Generates images in seconds
  • 🎯 Accuracy: Understands complex prompts well
  • 📐 Flexibility: Works with various aspect ratios

Getting Started​

Prerequisites​

  1. Install Cubby Image
  2. Get an API key from any of these providers:

Basic Usage​

  1. Open Cubby Image in Photoshop
  2. Select Nano Banana from the model dropdown
  3. Enter your prompt
  4. Click Generate

Writing Effective Prompts​

Nano Banana understands natural language well. Here are some tips:

Structure Your Prompt​

[Subject] + [Setting] + [Style] + [Details]

Example:

A mystical forest at dawn, 
magical atmosphere with floating lights, 
digital painting style, 
soft purple and blue tones

Use Descriptive Language​

❌ "castle" ✅ "medieval stone castle on a hilltop, surrounded by mist, dramatic lighting"

Specify Art Style​

  • photorealistic
  • digital art
  • oil painting
  • watercolor
  • 3D render
  • anime style

Advanced Techniques​

Controlling Composition​

Use positional terms:

  • "in the foreground"
  • "centered composition"
  • "viewed from above"
  • "wide angle shot"

Lighting and Mood​

  • golden hour lighting
  • dramatic shadows
  • soft ambient light
  • neon lights
  • volumetric fog

Quality Enhancers​

Add these to improve results:

  • highly detailed
  • 8k resolution
  • sharp focus
  • professional photography

Real-World Examples​

Product Photography​

High-end wireless headphones on a wooden desk,
minimalist setup, natural window lighting,
product photography, shallow depth of field,
professional commercial style

Landscape Art​

Vast desert landscape with sand dunes,
sunset with orange and pink sky,
single traveler silhouette,
cinematic composition, ultra wide angle

Character Design​

Steampunk inventor character,
Victorian era clothing with brass goggles,
workshop background with gadgets,
detailed illustration, concept art style

Tips and Tricks​

1. Iterate and Refine​

Don't expect perfection on the first try. Generate multiple variations and refine your prompt.

2. Use Seeds for Consistency​

If you find a good result, note the seed number to generate similar images.

3. Combine with Photoshop Tools​

  • Use generated images as a base layer
  • Add manual touch-ups with brushes
  • Combine multiple generations
  • Apply Photoshop filters and adjustments

4. Aspect Ratios​

Nano Banana works well with:

  • Square (1024x1024) - Social media
  • Portrait (768x1024) - Vertical designs
  • Landscape (1024x768) - Wide scenes

Common Issues and Solutions​

Image Not Matching Prompt​

  • Make your prompt more specific
  • Break complex ideas into simpler descriptions
  • Try adding "professional" or "high quality"

Unwanted Elements​

  • Use negative prompts if available
  • Specify what you DON'T want
  • Regenerate with adjusted prompt

Consistency Issues​

  • Use the same seed value
  • Keep core prompt elements the same
  • Only change specific details

Cost Optimization​

Nano Banana is cost-effective, but here are ways to optimize:

  1. Draft locally: Plan your composition in Photoshop first
  2. Batch similar prompts: Generate variations together
  3. Use lower steps: For drafts, fewer steps = faster & cheaper
  4. Refine manually: Use Photoshop for small adjustments instead of regenerating
