Starting from WPBakery Page Builder (formerly Visual Composer) version 4.6 it is possible to add a filter to image elements within WPBakery Page Builder adapted Media Library. There are currently 20+ image filters available for use in any WPBakery Page Builder element which uses Media Library as a source for image display.
Note: Image Filters do not replace original image instead of making duplication of the original image and applying a filter to it.
