Just as you can use the Lens Correction sliders to remove a vignette, you can use them to apply a vignette too. I often like to deliberately darken or lighten the edges of a photograph and use the Lens Correction sliders as basic dodge or burn tools for the corners of a photograph. Here are some suggestions as to how you can extend the vignetting options when working with Lightroom 2
Figure 1 At zero Roundness, the vignette shape matches the proportions of the cropped image. At +100, the Roundness slider makes the post-crop vignette more circular.
In Lightroom 2, we now have Post-Crop vignette controls that can do the same thing as the Lens Corrections sliders, except they are applied relative to the proportions of the cropped photograph and feature a Feather slider that allows you to soften or harden the vignette edge (see Figure 1).
Figure 2 This shows the original photograph used to create the examples shown in Figure 3, as the image was in the process of being cropped.
This is very much a tool for making creative effects. To give you some inspiration I have taken a single photograph and applied four different Post-Crop vignette settings (Figure 3). The main thing to point out here is that the Post-Crop sliders work just as well on uncropped images and the ability to apply both a global and a local vignette means that you can even experiment with combinations of the two settings when editing a cropped photograph. For example, in the bottom image in Figure 3, I combined a negative global vignette with a positive Post-Crop vignette.

When you use the crop overlay mode to edit the crop setting, the vignette effect is temporarily disabled.
