Lens Vignette the Right Way
A vignette is a compositional tool used by artists to direct the viewer’s focus to the center of the frame by fading out the edges.
In Blender, this is most often accomplished with an ellipse mask and multiply node. This approach has a few drawbacks:
- It must be tweaked any time the image size is changed
- There is very little artistic control
- There is no way to preserve edge highlights
If we take the time to build a better vignette and group it together into one handy node as explained in the video, we can save time in the long run.
