Distortion Types

• Barrel: Lines bow outward (common in wide-angle lenses, fisheye)
• Pincushion: Lines bow inward (common in telephoto lenses)
• Mustache: Complex distortion combining both (common in zoom lenses at certain focal lengths)

Correction Mode

Use correction mode to straighten distorted images. Select a lens profile that matches your lens, or manually adjust the distortion type and strength until straight lines in your image appear straight. Most useful for architectural photography where vertical and horizontal lines matter.
