Step 1 - Editing the Title Master
Any changes made to the title master will only affect the title slide and not any other slides in the presentation.
Select (View > Master >Title Master)
Step 2 - Master Layout Dialog
Step 3 - Changing the AutoLayouts
Step 4 - Formatting the AutoLayouts
Step 5 - Changing the Date, Footer and Number Areas
Step 6 - Things to Remember
Every presentation must have at least one slide master.
A presentation does not have to include a title master, although most do.
You can change the background and apply a background graphic exactly the same way as you would for the slide master.
