# Poster

## Triggers

poster, banner, event poster, promotional, marketing, movie poster, concert poster, advertising

## Defaults

- **Aspect ratio**: `3:4`
- **Resolution**: `2K`

## Visual Hierarchy

Specify this top-to-bottom reading flow in the prompt:

1. **Eye-catcher** — Hero image or bold visual
2. **Headline** — Main message in large, prominent text
3. **Supporting info** — Date, location, secondary details
4. **Call to action** — CTA text, website, QR code area

## Design Thinking

1. **Define the communication goal** — What should the viewer do after seeing this poster? (attend an event, buy a product, feel an emotion, learn something). Every design choice serves this goal
2. **Identify the single hero element** — A poster has ~2 seconds to grab attention. Decide what dominates: a bold image, a striking headline, or a dramatic color. Never compete for attention with multiple heroes
3. **Design for viewing distance** — A street poster is read from 3 meters; a social share from 15cm. Scale type and detail accordingly. When in doubt, go bigger and bolder
4. **Create emotional resonance** — The best posters trigger a feeling before the brain processes the words. Choose imagery, color, and composition that evoke the target emotion (urgency, excitement, elegance, nostalgia)
5. **Respect the medium** — A concert poster can be raw and experimental; a corporate event poster needs polish. Match the visual style to the audience expectation

## Aesthetics Guidelines

- **Focal point**: Every poster needs one unmistakable focal point. Use scale, contrast, color, or isolation to make it dominant. If you squint and nothing pops, the design fails
- **Color mood**: Use color psychology intentionally — warm tones (red/orange) for energy and urgency, cool tones (blue/green) for calm and trust, high saturation for youth and fun, muted tones for sophistication. Limit to 2-3 dominant colors plus neutrals
- **Typography as design**: In posters, type is not just information — it's a visual element. Oversized headlines, creative text placement, and expressive font choices can BE the design. Describe specific type treatments in the prompt (e.g., "massive bold sans-serif title filling the top third")
- **Composition techniques**: Use the rule of thirds, golden ratio, or bold centered symmetry. Describe the layout structure explicitly: "centered composition with radial symmetry" or "off-center subject with text balanced on the opposite side"
- **Contrast is everything**: Text must be legible at a glance. If placing text over imagery, specify overlay treatments.
- **Breathing room**: Resist the urge to fill every corner. Generous margins and whitespace make the key message louder, not quieter

## Prompt Rules

- Clarify design direction before generating — ask user about style, color mood, and tone if unspecified
- One poster = one clear message
- Put all text content in double quotes for accurate rendering
- For a series, use `--input-image` from the first to maintain consistency
