Internet makes you available lots of PowerPoint templates of varied categories on different topics. Most common categories are business, education, maps, animated, medical etc. Animated ppt templates are just awesome. They catch the interest of the audience and especially in case of medical templates it plays a very important role. By using animated templates in medical PowerPoint presentations you can easily explain your concepts in a wider way to your potential audience. Like if you are ready to make a presentation on heart and its functions than it would be easy to explain if you use animated template in your presentation because the image used in the template will show the pumping of heart and how the blood is flowing etc.
Composite photos _ These are photos with text or other graphics superimposed on the photo. I do this a lot with the quotations I post on social media and put into my newsletters. Import a photo into PowerPoint and expand it as large as you can on a slide. "Insert Shapes" and insert a text box onto the slide over the photo. Type the text you want to superimpose onto the photo and set the text color so that it contrasts nicely with the photo as background. Group the components and you have a composite photo.
