What is use of slide master in PowerPoint?
benefits of a master slideA master slide is beneficial in a presentation because you can propagate the general layout of the master slide through all the slides used in the presentation; that can include background, character format (i.e. size, font and else), date, slide number, icons or logos. In this sense, it also allows modifying the layout of the presentation much faster than if you had done it slide by slide. These are of four types:1. Title Master : When you open a new presentation in power point, the program assumes that you will begin your slide show with a title slide. Adding a title and subtitle to this slide layout is as easy as clicking in the text boxes provided and typing.2. Notes Master : This feature of power point enables adding notes top the slide and these notes could be seen afterwards in normal views. These notes might be some kind of special points or notifications.3. Handout Master : These are basically thumbnails of slides printed together on a sheet of paper. Such layouts can be cutomized to suit specific requirements. These are often printed to be sent for review to those who matter before and actual presentation is shown to an audience. During the presentation these handouts can be distributed to the audience.4. Slide Master : Each power point template comes with a slide master. The slide master controls the overall formatting and object placement for the presentation - Font type, Font color, size, background color, and certain special effects (like text shadowing). When you want to make the global change to the appearance of your slide you don't have to change each slide individually, just make changes once on the slide master and that will change other slides itself.
