Creating a Post-Crop Vignette
You can use the Post-Crop Vignette tool to create a light or dark vignette around your image.
The Post-Crop vignette sliders apply the vignette relative to the proportions of the cropped photograph. The Post-Crop Vignette tool features sliders to creatively control the vignette strength, radius, feathering, and roundness. A post-crop vignette can be applied to a cropped or uncropped photo.
You can save your settings as a preset for future use.

- In Develop mode, select the Tune tab.
 -
