Vignette and Sharpen

The Vignette and Sharpen tool allows you to correct non-desired masks and softening created by your lens.

Vignette

Correct non-desired masks created by your lens. With this same tool, you can also darken the corners of your photo to create an artistic mask.

Correct Vignette

1. The amount allows you to change how weak or strong the vignette mask is applied to your photograph. A negative value allows you to add a vignette and a positive value allows you to remove the vignette.
   
   
2. The Mid point allows you to specify the photo area affected by the correction. A lower value practically modifies the entire photo and a high value modifies only the border of your photo. A zero value adjust nothing in your photo.
