<Info>
  **No negative prompts**: FLUX.2 does not support negative prompts. Focus on describing what you want, not what you don't want.
</Info>

## Prompt Structure

Use this framework for consistent results: **Subject + Action + Style + Context**

* **Subject**: The main focus (person, object, character)
* **Action**: What the subject is doing or their pose
* **Style**: Artistic approach, medium, or aesthetic
* **Context**: Setting, lighting, time, mood, or atmospheric conditions

</Tabs>

Word order matters - FLUX.2 pays more attention to what comes first. Put your most important elements at the beginning:

**Priority order**: Main subject → Key action → Critical style → Essential context → Secondary details

**Prompt length guidance**:

* **Short (10-30 words)**: Quick concepts and style exploration
* **Medium (30-80 words)**: Usually ideal for most projects
* **Long (80+ words)**: Complex scenes requiring detailed specifications

## Photorealistic Styles

FLUX.2 generates photorealistic images from simple, natural language prompts. Reference specific eras, cameras, and techniques for distinctive looks.

### Style Reference Guide

    <PromptDisplay prompt="An old faded family portrait photograph from the early 1900s showing a family of five standing stiffly in front of their modest wooden farmhouse" />
  </Tab>
</Tabs>

### Camera and Lens Simulation

Be specific about camera settings for authentic results:

```
Shot on Hasselblad X2D, 80mm lens, f/2.8, natural lighting
```

```
Canon 5D Mark IV, 24-70mm at 35mm, golden hour, shallow depth of field
```

<Tip>
  For photorealism, specify camera models, lenses, and film stocks. "Shot on Fujifilm X-T5, 35mm f/1.4" produces more authentic results than just "professional photo."
</Tip>

## Typography and Design

FLUX.2 generates clean typography, product marketing materials, and magazine layouts.

  </Tab>
</Tabs>

### Text Rendering Tips

FLUX.2 can generate readable text when you describe it clearly:

* **Use quotation marks**: *"The text 'OPEN' appears in red neon letters above the door"*
* **Specify placement**: Where text appears relative to other elements
* **Describe style**: "elegant serif typography", "bold industrial lettering", "handwritten script"
* **Font size**: "large headline text", "small body copy", "medium subheading"
* **Color**: Use hex codes for brand text: *"The logo text 'ACME' in color #FF5733"*

## Infographics and Data Visualization

FLUX.2 can generate infographics with clean typography and structured layouts.

### Infographic Template

```json theme={null}
{
  "type": "infographic",
  "title": "Your Main Title",
  "subtitle": "Supporting context",
  "sections": [
    {
      "heading": "Section 1",
      "content": "Key information",
      "visual": "icon or chart type"
    }
  ],
  "color_scheme": ["#primary", "#secondary", "#accent"],
  "style": "modern, clean, corporate"
}
```

**Example Prompt:**

*"Create a vertical infographic about coffee consumption worldwide. Title: 'Global Coffee Culture'. Include 3 sections with statistics, use icons for each country, color scheme #4A2C2A (brown) and #F5E6D3 (cream). Modern minimalist style with clean typography."*

<Frame caption="Data visualization with clean typography">

</Frame>

## Multi-Language Prompting

FLUX.2 understands multiple languages. Prompt in your native language for more culturally authentic results.

<Tabs>
  <Tab title="French">

    </Frame>

    <PromptDisplay prompt="서울 도심의 옥상 정원, 저녁 노을이 지는 하늘" />
  </Tab>
</Tabs>

<Tip>
  Prompting in the native language of the content you're creating often produces more culturally authentic results - local markets, architecture, and atmosphere are rendered with greater accuracy.
</Tip>

## Comic Strips and Sequential Art

Create consistent comic panels with character continuity. The key is to define your character in detail and maintain that description across panels.

### The Diffusion Man Story

Generate each panel separately while keeping character descriptions consistent:

<Columns cols={2}>
  <Frame caption="Panel 1: The Crisis">
    ![Worried scientist in server room](https://cdn.sanity.io/images/2gpum2i6/production/ff4d90d49054184073fcf25b86ac9bcb96f0eb41-1440x832.jpg)
  </Frame>

  <Frame caption="Panel 2: The Transformation">

  </Accordion>
</AccordionGroup>

<Tip>
  **Character Consistency**: Notice how Diffusion Man's description stays detailed and consistent across panels—brown skin tone, short natural fade haircut, gradient bodysuit from purple to blue to pink, neural network emblem, purple half-mask. Repeat these details in every panel prompt.
</Tip>

## JSON Structured Prompting

For complex scenes and production workflows, FLUX.2 interprets structured JSON prompts, giving you precise control over every aspect of your image.

**When to use JSON**:

* Production workflows requiring consistent structure
* Automation and programmatic generation
* Complex scenes with multiple subjects and relationships
* When you need to iterate on specific elements independently

**When natural language works better**:

* Quick iterations and exploration
* Simple, single-subject scenes
* When prompt length isn't a concern
* Creative workflows where flexibility matters

FLUX.2 understands both formats equally well—choose based on your workflow needs.

### The Base Schema

```json theme={null}
{
  "scene": "overall scene description",
  "subjects": [
    {
      "description": "detailed subject description",
      "position": "where in frame",
      "action": "what they're doing"
    }
  ],
  "style": "artistic style",
  "color_palette": ["#hex1", "#hex2", "#hex3"],
  "lighting": "lighting description",
  "mood": "emotional tone",
  "background": "background details",
  "composition": "framing and layout",
  "camera": {
    "angle": "camera angle",
    "lens": "lens type",
    "depth_of_field": "focus behavior"
  }
}
```

### Precise Color Control Example

Break down products into components and assign exact hex colors to each part for brand consistency:

<Columns cols={2}>
  <Frame caption="Input reference">

      "#86E04A",
      "#615E5E",
      "#000000"
    ]
  }
  ```

  Each subject has a `type`, `description` with explicit color specification, `position`, and `color_match: "exact"` for precise control.

  "subjects": [
    {
      "description": "Minimalist ceramic coffee mug with bright red steam rising from hot coffee inside",

      "pose": "Stationary on surface",
      "position": "Right side of the black mug on polished concrete surface",
      "color_palette": ["matte yellow ceramic"]
    }
  ],
  "style": "Ultra-realistic product photography with commercial quality",
  "color_palette": ["matte black", "matte yellow", "bright red", "concrete gray", "soft white highlights"],
  "lighting": "Three-point softbox setup creating soft, diffused highlights with no harsh shadows",
  "mood": "Clean, professional, minimalist",
  "background": "Polished concrete surface with studio backdrop",
  "composition": "rule of thirds",
  "camera": {
    "angle": "high angle",
    "distance": "medium shot",
    "focus": "Sharp focus on steam rising from coffee and both mugs in frame",
    "lens-mm": 85,
    "f-number": "f/5.6",
    "ISO": 200
  }
}
```

<Frame caption="Step 3: Changed the steam color to bright red">
  ![Product shot with black and yellow mugs, red steam rising from the black mug](https://cdn.sanity.io/images/2gpum2i6/production/50a2056e955f4f231e7968e69c3a89fd7d78270d-1024x768.webp)
</Frame>

<Tip>
  You can include the JSON directly in your prompt, or flatten it into natural language. FLUX.2 understands both formats.
</Tip>

## Multi-Reference Image Editing

<Note>
  \*\[pro] API has a 9MP total limit for input+output. At 1MP output you can use up to 8 reference images, at 2MP output up to 7, and so on.
</Note>

Multi-reference works well for:

* **Fashion shoots**: Combine clothing items into styled outfits
* **Interior design**: Place furniture and decor in rooms
* **Product composites**: Combine multiple products in scenes
* **Character consistency**: Maintain identity across variations

### Fashion Editorial Example (8 references)

**Prompt:** *"A spiritual architectural photograph captured on expired Kodak Ektachrome 64 slide film cross-processed from 1987 with a 35mm spherical lens at f/5.6, featuring model standing before small forest chapel in clearing. The model wears the outfit, positioned on stone steps leading to wooden chapel, red creating stark contrast against weathered brown timber. Background shows traditional Schwarzwald chapel - dark wood construction with small bell tower, carved wooden door, religious paintings under eaves, surrounding clearing with wild flowers, tall firs creating natural cathedral, small cemetery with wooden crosses. Dappled forest light at 1/125. Cross-processed Ektachrome showing extreme color shifts - cyan-magenta split, warm wood tones pushed to orange-brown, oversaturated red, crushed black shadows, blown highlights, heavy grain creating mysterious atmosphere. Composition emphasizes sacred spaces and pilgrimage. Thomas Struth church interiors, Candida Höfer architectural documentation, religious tourism meets fashion editorial, spiritual Schwarzwald mysticism."*

<Frame caption="8 input references (clothing, accessories, style elements) → combined output">
  ![Eight input reference images with generated output](https://cdn.sanity.io/images/2gpum2i6/production/51696bb4ac2972e1dda5f3e68f748210f392c4f4-4861x1863.jpg)
</Frame>

<Tip>
  For multi-reference editing, describe how each input should be used. The model combines clothing items, accessories, and style references into a cohesive scene based on your prompt.
</Tip>

## Prompt Upsampling

FLUX.2 includes a `prompt_upsampling` parameter that automatically enhances your prompt. Use it for:

* Quick iterations without crafting detailed prompts
* Exploring creative variations
* When you have a basic concept but want richer output

<Note>
  Prompt upsampling adds detail and context to your prompt automatically. Your original intent is preserved while the model expands on visual elements.
</Note>

## Aspect Ratios and Resolution

Choose aspect ratios based on your use case:

| Aspect Ratio          | Use Case                        | Example Dimensions   |
| --------------------- | ------------------------------- | -------------------- |
| **1:1** (Square)      | Social media, product shots     | 1024×1024, 1536×1536 |
| **16:9** (Widescreen) | Landscapes, cinematic shots     | 1920×1080, 1536×864  |
| **9:16** (Portrait)   | Mobile content, portraits       | 1080×1920, 864×1536  |
| **4:3** (Classic)     | Magazine layouts, presentations | 1536×1152, 1024×768  |
| **21:9** (Ultrawide)  | Panoramas, wide scenes          | 2048×864             |

**Resolution limits**: Minimum 64×64, maximum 4MP (e.g., 2048×2048). Output dimensions must be multiples of 16. Recommended up to 2MP for most use cases.

## Best Practices Summary

<AccordionGroup>
  <Accordion title="Structure for Control">
    Use JSON structured prompts when you need precise control over multiple elements. Start simple and add complexity as needed.
  </Accordion>

  <Accordion title="Be Specific with Colors">
    Always associate hex codes with specific objects. "The car is #FF0000" works better than "use red #FF0000 in the image."
  </Accordion>

  <Accordion title="Describe What You Want">
    FLUX.2 has no negative prompts. Instead of "no blur," say "sharp focus throughout." Instead of "no people," describe an "empty scene."
  </Accordion>

  <Accordion title="Reference Camera and Style">
    For photorealism, specify camera models, lenses, and film stocks. "Shot on Fujifilm X-T5, 35mm f/1.4" produces more authentic results than "professional photo."
  </Accordion>

  <Accordion title="Use Native Languages">
    Prompt in the language that best describes your desired cultural context. French for Parisian scenes, Japanese for anime styles.
  </Accordion>

  <Accordion title="Layer Multi-Reference Carefully">
    When using multiple input images, clearly describe the role of each: subject from image 1, style from image 2, background from image 3.
  </Accordion>
