<subsection Relation between Slides and Talk>
In a good Presentation, your Slides and your Talk should extend each other, but still, relate to each other. While talking you can give much more background information than could ever fit onto a slide, while an Image can do much more than you talking. Also, your slides allow somebody slightly lost (thinking about some subtopic for example) to catch up, while your talk can be much less formal. In the best Presentations, somebody listening to your/looking at your presentation will get much more out of this than somebody looking at your slides and later listening to your talk (without slides), while both function on their own too.
