Does Lightroom offer a Focus Mask Plugin? I see that Capture One has a focus mask, but I am used to using Lightroom and like Lightroom, does anyone used both of these programs? Has anyone tried the one plugin I found at capturemonkey.com, sounds like some dude made it which makes me skeptical if I want to try and use it!

This is an early beta version of focus mask plugin for Lightroom 4.x and 5.x. After installation, you can open the plugin from File / Plug-in Extras / Focus Mask menu item. The plugin opens with either single image, or several, depending on your current selection. In single image mode, the photo is shown in larger size, and in multiple images, the view can be scrolled. Currently, the amount of images is restricted to 32.
