PowerPoint Tip: Animation Using Reveals
Recently I needed to animate parts of a graph. I tried the animation tools in PowerPoint, but they would not allow me to reveal the parts of the graph the way I wanted to. If this happens to you when wanting to reveal parts of a graph or a graphic, here is an option to consider.
The technique involves thinking in a different way. Instead of the normal approach of animating each element to come on to a slide, this approach reveals the elements that are already on the slide, but are covered up by other elements. It is like we used to do with overhead transparencies when we would cover part of the transparency up with a piece of paper and reveal each point by moving the paper.
There are two ways to implement this technique. The first is to begin by saving the background as an image. Then, add this image to the slide. Size it so that the image covers up the entire slide (it now looks like the slide has nothing on it). Use the cropping handles to crop the image to the desired size, covering up only the element you want to reveal later. In the animation task pane, apply an exit animation to this image so that when you advance, the image is removed from the slide, revealing what is underneath.
The other way to implement this technique is to use the transparent background technique taught by Glen Millar, who I saw demonstrate it at the PowerPoint Live conference recently. This technique uses the ability to fill a shape with the background of the slide. First, draw a shape, for example a rectangle, on the slide, covering up the element you want to reveal. Format the shape so that it has no line and the fill effect is set to Background. Again, animate this shape so that it exits when you advance on this slide.
Using either approach, you can achieve the building of the elements on the slide in the order that you want to discuss them in. The only downside to this technique is that when you print the slide, the shape or image covers up the other element and it appears that there is nothing there on the slide. To get around this, create a duplicate hidden slide that does not use this technique and print this hidden slide instead of the slide you use for presenting.

These are both good techniques, but your readers may like to know that my Opazity add-in for PowerPoint can produce more dramatic reveal techniques, with more flexibility in shape choice. Also, the image does not need to be placed on the slide background. They might like to watch the demonstration videos and download the instructions on http://www.opazity.com to see how.
