Why Use JSON for AI Prompts?
JSON (JavaScript Object Notation) structured prompts offer significant advantages over plain text prompts:
✓Organized Structure: Complex ideas are broken into clear sections (subject, lighting, composition, constraints).
✓Consistent Results: Structured prompts produce more predictable, reproducible outputs.
✓Easy to Edit: Modify specific parameters without rewriting the entire prompt.
✓Reference Support: Include face, clothing, and background reference policies for identity-consistent images.
✓Negative Prompts: Clearly specify what to avoid (blur, distortion, bad anatomy) for cleaner results.
Understanding Negative Prompts
Negative prompts tell AI what to avoid in generated images. They're essential for professional-quality results in Nano Banana Pro, Midjourney, and Stable Diffusion.
Common negative prompts for portraits:
blur, deformed hands, extra fingers, bad anatomy, low quality, watermark, text, cartoon, CGI, plastic skin, overexposed, cropped
Our generator automatically includes smart negative prompts based on your category. You can also add custom negative prompts for specific requirements.
