[MUSIC] Overall, Lightroom has various forms of operation. One is related to organizing, grouping, and searching for files, and navigating through them on your hard disks. Another is related to a set of operations and processes you can use to change the final characteristics of a photograph. And the final one relates to the form of the desired output. The first two of them related to the Library and Develop modules are used almost every time you use Lightroom. The other five, Map, Book, Slideshow, Print, and Web modules are used from time to time to create final presentation formats related to the work done in the fist two modules. Let's look more closely at the overall layout of the Lightroom interface on the screen, and get an overview of the menu structure as well. The Lightroom interface is divided into four panels positioned around a rectangular work area. One panel is at the top, and another at the bottom, and the third is on the left, and the final one is on the right. The panels can be opened and closed using the four triangles in the middle of the outer side of each rectangular panel. Clicking the triangles opens or closes the panel. Clicking again reverses the previous action. The left panel, Closed, and now, open. The right panel, closed, Open, Closed, open. The top panel, Closed, open. The bottom panel, closed and open, The top panel is where you choose the module and its function. The top panel is the same in each of the modules. On the left, it has the name of the programme or a customised nameplate label, like your name or whatever you assign it. On the right side, it has the name of each module, Library, Develop, Map, Book, Slideshow, Print, or Web. Clicking on those names changes the content of some of the other panels according to the name and function chosen. You'll see different things in the library panels than in the develop panel. But before going into the distinction of the panels, we need to look briefly at how to get photographs into Lightroom, which is called importing. And at the catalog, and how to know where you are in it and where the catalog is on your computer. And finally, at the menus, which are the same from module to module and are found in the menu bar above the interface.
