Compensate for lens vignetting

Vignetting is a lens defect that causes the edges of an image, especially the corners, to be darker than the center. It is particularly noticeable when the photo contains a subject that is supposed to be an even shade or tone, such as the sky in a landscape image. The Lens Correction sliders in the Vignettes panel of the Develop module allow you to correct these apparent lens distortions.

Lens corrections can be applied only to original, uncropped photo edges. Lens corrections adjust exposure values to brighten dark corners.

  1. In the Lens Correction area of the Vignettes panel of the Develop module, move the Amount slider to the right (positive values) to lighten the corners of the photo. Move the slider to the left (negative values) to darken the corners of the photo.
  2. Move the Midpoint slider to the left (lower value) to apply the Amount adjustment to a larger area away from the corners. Move the slider to the right (higher value) to restrict the adjustment to an area closer to the corners.
