Lens

Lens corrects geometric distortion, chromatic fringe, and vignetting. Profile support may prefill or guide corrections; the manual controls remain available.

Controls

• Distortion corrects barrel or pincushion curvature.
• Fringe R/C corrects red/cyan lateral chromatic separation.
• Fringe B/Y corrects blue/yellow separation.
• Lens vignetting brightens the corners back up to undo the falloff the lens put there.
• Lens vig. range controls how far that correction reaches toward the center.

Correct distortion before final crop because straightening edges can expose empty corners. Inspect high-contrast edges near the frame at 100% while adjusting fringe.

The controls here undo what the glass did. For a falloff you want, use Vignette, and correct first: working the other way makes this correction fight a look you chose.
