What is Adaptive Lens Correction
Applying Lens Corrections can be a mixed bag. Often by using Adobe’s built in lens profiles to correct for distortion, you might notice over or under vignetting corrections. The Impossible things formula takes advantage of Lightroom’s incredible lens profile library while using a little mathematical magic to accurately correct for lens vignetting.
Important Note: This option is currently dependent on system resources, so depending on your system and Lightroom version, it is usually a best practice to apply in groups of 100-200 photos to ensure the additional vignetting correction gets applied to all photos.
