Vignetting is a widely used resource in color correction, and serves to focus attention on the center of the image by darkening the outer edges.
Today we have uploaded a DaVinci Resolve PowerGrade that will help you to apply the vignetting directly without the need to do the mask and the luminance adjustment afterwards.
To download it you have to be part of the group “LUTs Exchange”, inside Red 709 (from here you will access directly). And this post explains how to import and export Power Grades in the DaVinci color correction system.
We remind you that through the same group you can share your own looks with the rest of the users.
