# Nano Banana Image Prompt Generator

Generate high-quality prompts for Gemini 2.5 Flash Image using proven best practices from October 2025.

## Core Principle

**Describe scenes naturally, don't list keywords.**

❌ `woman, business suit, office, professional`
✅ `A professional businesswoman in navy suit stands confidently in modern glass-walled office overlooking city skyline. Warm afternoon light streams through windows.`

## Prompt Structure

### Basic Template

```
A [SHOT TYPE] of [SUBJECT] [ACTION] in [ENVIRONMENT]. 
[LIGHTING] creates [MOOD]. [CAMERA/STYLE DETAILS]. [ASPECT RATIO].
```

### Components

1. **Subject & Action** - Who/what and what they're doing
2. **Setting** - Where the scene takes place
3. **Lighting** - Natural/artificial light sources and quality
4. **Mood** - Emotional tone or atmosphere
5. **Technical Details** - Camera, lens, style specifics
6. **Format** - Aspect ratio or dimensions

## Prompt Length

- **Short (10-20 words)**: Quick generation, minimal control
- **Medium (50-100 words)**: ⭐ RECOMMENDED - balanced control
- **Long (100-200 words)**: Maximum control for complex scenes

## Photography Prompts

### Example
```

```

## Art & Illustration Prompts

wonder and tranquility. 4:5 portrait format.
```

## Text Rendering

**Best Practices:**

in white script font at bottom. Ocean sunset background. Cinematic style.
```

## Multi-Turn Editing Workflow

**Example sequence:**

2. "Change background to modern office"
3. "Make her wearing glasses"
4. "Add warmer lighting"

surface. Soft diffused studio lighting from 45-degree angle to minimize
