slide show

(1) A collection of pages arranged in sequence that contain text and images for presenting to an audience. It often refers to a Microsoft PowerPoint presentation. See presentation graphics, PowerPoint and slide transition.

(2) The continuous display of a folder of images on the computer, either sequentially or at random. Slide shows are created by stand-alone applications or a slide show function within a photo editor. Such programs generally offer a variety of transition effects between images (cut, fade, wipe, etc.), which can be selected or interspersed at random. The interval between images is also selected by the user as well as an audio file to provide background music.

Some programs allow the slide show to be burned onto a CD or DVD with a self-contained viewer that can be sent to friends and family. See photo editor.

The Real Slide Show

Beginning in the 1950s, 35mm transparencies (slides) were projected onto a screen or white wall. The slides were inserted into a carousel tray, and each one dropped into the light path as the tray was rotated. Kodak was a major supplier of slide projectors as in this example.
