Best Practices
- Use clear images - Higher quality = better analysis
- Crop to relevant area - Remove unnecessary context
- Ask specific questions - Vague prompts get vague answers
- Provide context - Tell Gemini what you're looking for
- Verify extracted text - OCR isn't perfect
- Multiple angles - Use multiple images for complex subjects
