Mode Selection

Ask your users before generating:

"Do you want fast & cheap, or high quality?"

Best Practices

For Products

• Lighting: Original image should have even lighting for best results
• Contrast: High contrast between product and background helps accuracy
• Shadows: Request shadow preservation for natural-looking results
• Resolution: Higher resolution input yields better edge quality

For Portraits

• Hair: Mention hair type in prompt for better edge detection
• Clothing: Describe clothing edges if they blend with background
• Accessories: Note glasses, jewelry, or items that need preservation

For Complex Subjects

• Transparency: Mention glass, smoke, or translucent elements
• Fine Details: Specify fur, feathers, or intricate patterns
• Multiple Subjects: Describe what should be kept vs removed

Prompt Tips

When requesting background removal, include:

1. Subject Type: Product, person, animal, object
2. Edge Complexity: Simple edges vs hair/fur/fine details
3. Output Format: Transparent PNG or replacement background
4. Background Color: Specific hex code if replacing with solid color
5. Use Case: E-commerce, social media, compositing, etc.

Example Prompt Structure

"Remove the background from this [subject type].
[Specific edge requirements like hair or fur details].
Output as [transparent PNG / white background / specific scene].
This is for [use case] - [any specific requirements]."
