Suitable profiles can be located easily based on the EXIF data automatically recorded with the image, and if a suitable profile is not present in the Lens Correction filter, then with a single click within the dialog box, you can search online for the correct profile to meet your needs. Individual error types can be selected in the filter’s settings, as can options for handling any transparent areas that surround the corrected image.
