Best Practices for Visual AI
Effective Prompting for Images
Be Specific About Style
❌ "A cat" ✅ "A fluffy orange tabby cat sitting in a sunny window, photographic style, shallow depth of field"
Include Technical Details
- Lighting: "soft natural lighting", "golden hour", "studio lighting"
- Camera angle: "bird's eye view", "close-up portrait", "wide establishing shot"
- Style: "photorealistic", "watercolor painting", "digital art", "vintage film"
Specify Composition
- "centered composition"
- "rule of thirds"
- "negative space on the left"
- "foreground, middle ground, background"
Quality Control
Check for Common Issues
- Text legibility in generated images
- Anatomical accuracy for people and animals
- Consistent lighting and shadows
- Object placement and scale
- Brand safety and appropriateness
Iteration Strategy
