Most of the work of creating slideshows in Lightroom Classic CC is done in the Slideshow module, where you can select layout templates, choose transitions, and set playback options.
In the Slideshow module, the left panels contain a list of templates and previews of their layouts. The Slide Editor view in the center of the workspace displays the photos in the selected slide template. The toolbar below the Slide Editor contains controls for playing a preview of the slideshow, refining the selection, and adding text to the slides. The right panels contain controls for modifying the template, adding text to the slide layout, and selecting playback settings. See Slideshow module panels and tools.

You can also play an "impromptu" slideshow in any module by choosing Window > Impromptu Slideshow. An impromptu slideshow uses the current template and settings in the Slideshow module. Playing an impromptu slideshow in the Library module is a convenient way to quickly view images in a folder at full-screen size and rate, rotate, or delete photos using keyboard shortcuts.
In the Library module, select photos in the Grid view or Filmstrip. Or use the Folders or Collections panel to select an entire folder or a collection of photos to use for the slideshow. See Selecting photos in the Grid view and the Filmstrip.
Switch to the Slideshow module. If your source photos are in a collection or in a folder that doesn't contain any subfolders, drag the photos in the Filmstrip to arrange them in the desired order. See Rearrange slide order.
Alternatively, let Lightroom Classic CC choose the order in which the slides play: In the Playback panel on the right side of the Slideshow module, select Random Order. See Randomize the slide order.
A template provides a basic layout for your slides.
On the left side of the Slideshow module, move the pointer over a name in the Template Browser; a preview of the template appears in the Preview panel above the Template Browser. Click a template name to select it for your slideshow. See Choose a slide show template.
Customize your slideshow by modifying the options in the Options, Layout, Overlays, Backdrop, and Titles panels. For example, add a drop shadow; specify whether to show your identity plate or a caption; and specify a color or image for the background. See Adding overlays to slides and Set the slide background.
Click the Preview button in the lower-right corner of the Slideshow module to see the slideshow play in the Slideshow Editor view. Click the Play button to play the slideshow in full-screen mode. Use the buttons in the toolbar to pause, stop, or advance slides. See Preview a slideshow and Play a slideshow.
To share your slideshow, save it as an MP4 video that can play with transitions and music. Or, save it as a static PDF document that others can open. Click the Export Video or Export PDF button in the lower-left corner of the Slideshow module. See Export a slideshow for information on the video and PDF options.
Save your slideshow layout as a custom template so you can reuse it easily. Or save the slideshow settings as a slideshow collection. A slideshow collection lets you easily return to a specific set of slide show options for a collection of photos. See Create custom slideshow templates and Save slide show settings as a slideshow collection.
