Fixing Lens Vignetting

Vignetting, an unusual darkness in the corners of images, is the result of the inability of the lens to distribute light into the corners of the image. Fix lens vignetting in the Develop Tools pane by brightening the corners of the image.

Settings can be set as a preset for future use.

To fix vignetting:

1. In the Develop Tools pane, select the Geometry tab.
2. In the Vignette Correction group, adjust the image as described below.

Right-click a slider to reset to the default value.

Vignette Correction Options

Strength	Adjust how much the corners of the image will be brightened.
Radius	Adjust the distance from the corners of the image that pixels will be brightened. The higher the radius, the closer to the center of the image pixels will be brightened.

Click the Show Grid button to display a grid over the image. This tool is useful when fixing alignment in images. When the grid is not activated, it is gray .
