Crop and Expand
The process of framing an image and utilizing AI to generate plausible content beyond the original sensor boundaries.
Core Concepts
- Generative Expand: AI-driven extension of image borders, allowing for aspect ratio changes without cropping out subject matter.
- Render to DNG: Exporting AI-expanded images as raw DNG files to preserve metadata and allow further non-destructive editing in Lightroom Classic.
- Mask Refinement: Improved precision in selecting areas for expansion or editing, reducing artifacts at boundaries.
