Somehow, this does not appeal to me because it takes a lot of time and effort. Many people choose to use zoomed animations.
Now, what do you do under such circumstances? If I am correct, you create hidden slides to highlight certain portions of a slide and bring them up as zoomed in slides of specific portions. Besides, if a detailed picture or some dense stuff is packed in, it gets too difficult for the presenter to grab everyone’s attention. And when the number is really big, it becomes difficult for the audience at the back or the corners to follow the slide contents. Sometimes you have to address huge crowds when you are presenting things.
