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
[STYLE] illustration of [SUBJECT] [ACTION/POSE]. [COMPOSITION] with
[COLOR PALETTE]. [TECHNIQUE/MEDIUM]. Inspired by [REFERENCE],
emphasizing [QUALITIES].
```
### Common Styles
- Watercolor painting
- Digital art
- Oil painting
- Pencil sketch
- Ink drawing
- Anime/manga
- Pixel art
- Minimalist vector
### Example
```
Watercolor illustration of young girl reading book under oak tree. Seated
cross-legged in sun-dappled clearing with wildflowers. Soft, loose brushstrokes
with pastel color palette of greens, yellows, pinks. Transparent washes create
dreamy, ethereal quality. Inspired by children's book illustration, emphasizing
wonder and tranquility. 4:5 portrait format.
```
## Text Rendering
**Best Practices:**
- Keep under 25 characters total
- Maximum 2-3 phrases
- Specify font style (bold, script, sans-serif)
- Put exact text in quotes
- Describe position explicitly
**Example:**
```
Movie poster with bold red text "SUMMER" at top and "Adventure Awaits"
in white script font at bottom. Ocean sunset background. Cinematic style.
```
## Multi-Turn Editing Workflow
Nano Banana excels at conversational editing. Make one change at a time.
**Example sequence:**
1. "Create professional headshot of woman in business attire"
2. "Change background to modern office"
3. "Make her wearing glasses"
4. "Add warmer lighting"
## Product Photography
### Template
```
High-resolution product photo of [PRODUCT] on [SURFACE]. [LIGHTING]
to [PURPOSE]. Camera angle: [TYPE] to showcase [FEATURE]. Ultra-realistic,
sharp focus on [DETAIL]. [ASPECT RATIO].
```
### Example
```
High-resolution product photo of stainless steel smartwatch on white marble
surface. Soft diffused studio lighting from 45-degree angle to minimize
reflections and show screen clearly. Camera angle: slight overhead to showcase
circular face and metal band texture. Ultra-realistic, sharp focus on watch
face display. 1:1 format for e-commerce.
```
## Landscape Photography
### Template
```
[TYPE] landscape of [LOCATION] at [TIME]. [WEATHER/ATMOSPHERE].
[FOREGROUND ELEMENTS]. Shot with [LENS] from [VANTAGE POINT].
[COMPOSITION]. Professional landscape photography with [GRADING]. [MOOD].
```
### Example
```
Dramatic landscape of mountain lake at golden hour. Wispy clouds catch
warm orange light over snow-capped peaks. Weathered dock extends into
mirror-still water as foreground. Shot with 16mm wide-angle from low
lakeside vantage. Rule-of-thirds composition places horizon in upper third.
Professional landscape photography with warm color grading. Serene yet majestic.
```
## Abstract Art
### Template
```
[MOVEMENT] abstract exploring [CONCEPT]. [COMPOSITION] with [COLORS/TEXTURES].
[MEDIUM] emphasizing [GOALS]. [CONTEXT].
```
### Example
```
Bold geometric abstract exploring tension and harmony. Overlapping angular
shapes with vibrant primary colors against deep black. Digital art emphasizing
sharp edges and color interaction. Large-scale wall art format, 16:9.
```
## Common Pitfalls
**Avoid:**
- Keyword lists without context
- Vague descriptions
- Conflicting style instructions
- Overly complex text rendering
- Too many simultaneous changes in edits
**Instead:**
- Use complete sentences
- Be specific about details
- Maintain style consistency
- Keep text simple
- Edit iteratively
## Style References
When requesting specific artistic styles, reference:
- Art movements (impressionism, art deco)
- Artists (in style of Van Gogh's brushwork)
- Media (watercolor, oil painting, digital art)
- Eras (1950s photography, modern minimalist)
## Aspect Ratios
- **1:1** - Square (social media, profile pics)
- **16:9** - Landscape (presentations, headers)
- **9:16** - Portrait (mobile, stories)
- **4:5** - Portrait (Instagram posts)
- **2:3** - Classic portrait
- **3:2** - Standard photo
## Quick Prompt Checklist
✅ Subject clearly described
✅ Action or pose specified
✅ Environment/setting detailed
✅ Lighting source and quality
✅ Mood or atmosphere
✅ Style or technical specs
✅ Aspect ratio chosen
✅ Complete sentences, not keywords
## Common Issues & Solutions
### Prompt Quality Issues
**Issue**: Generic or vague output
**Cause**: Prompt too short or lacks specificity
**Solution**: Expand to 50-100 words. Add lighting details, mood, and specific technical specs (lens, style, etc.).
**Example**:
- ❌ Too vague: "A woman in an office"
- ✅ Specific: "Professional businesswoman in navy suit stands confidently in modern glass-walled office overlooking city skyline at golden hour. Warm afternoon light streams through floor-to-ceiling windows creating soft rim lighting. Shot with 50mm f/2.0, shallow depth of field blurs cityscape background. Confident yet approachable mood. 4:5 portrait format."
