Tips for Better Results
- Be specific - More detail = better results
- Include style keywords - "4k", "cinematic", "digital art", "photorealistic"
- Specify lighting - "dramatic shadows", "rim lighting", "candlelit"
- Mention perspective - "from below", "bird's eye view", "close-up"
- Use quality=hd for hero images and important assets
Troubleshooting
"Invalid API key" - Check echo $OPENAI_API_KEY is set
"Content policy violation" - Rephrase prompt to avoid flagged content
Image looks wrong - DALL-E interprets prompts creatively; try multiple generations or refine prompt
