Image Outpainting / Extension

Extend images beyond their original boundaries using each::sense. This skill uses AI to intelligently generate new content that seamlessly blends with the original image, enabling aspect ratio conversions, background expansion, and creative image extensions.

Features

• Horizontal Extension: Expand images left and right for wider compositions
• Vertical Extension: Add content above and below for taller images
• Aspect Ratio Conversion: Transform portrait to landscape or vice versa
• Background Expansion: Add more context and environment to photos
• Uncropping: Recover or imagine content outside the original frame
• Panoramic Creation: Turn single images into wide panoramic views
• Product Photo Enhancement: Extend product shots for banners and ads
• Artwork Extension: Expand illustrations and digital art

Prompt Tips for Outpainting

When requesting image extensions, include these details in your prompt:

1. Direction: Specify horizontal, vertical, or all directions
2. Target Ratio: Mention the desired aspect ratio (16:9, 21:9, 3:1, etc.)
3. Content Guidance: Describe what should appear in extended areas
4. Style Matching: Request consistent lighting, colors, and atmosphere
5. Subject Position: Specify where the original subject should be placed
6. Use Case: Mention if it’s for a banner, social media, print, etc.

Example Prompt Structure

"Extend this [image type] [direction] to [target ratio/size].
[Describe what to add in extended areas].
Maintain [lighting/style/atmosphere] consistency.
Position the original [subject] in the [location]."

Mode Selection

Ask your users before generating:

“Do you want fast & cheap, or high quality?”

Best Practices

For Best Results

• High-quality source: Start with a high-resolution original image
• Clear edges: Images with distinct edges outpaint more seamlessly
• Consistent lighting: Describe the lighting in your prompt for better matching
• Reasonable extensions: Extending 2-3x the original size works best
• Iterate: Use sessions to refine results progressively

Common Pitfalls to Avoid

• Don’t extend too far in one step – do it gradually
• Avoid extending images with complex foreground elements at edges
• Don’t expect perfect results with heavily stylized or abstract images
• Be specific about what should appear in extended areas
