This tutorial briefly explains how to use the Lightroom Plugin included in Photomatix Pro.
You must first select the photos you want to process. Photomatix is designed to work with bracketed photos of an HDR scene, but you may also use it with a single photo.
In Lightroom, select the bracketed photos in either the Filmstrip or the Grid.
To invoke the Plugin, right-click the selected photos and choose Export > Photomatix Pro.
Alternatively, you can invoke the Plugin by choosing File > Plug-in Extras > Export to Photomatix Pro.
Note: You can find more information on HDR and how to take bracketed photographs on the video tutorials page.
