Use photos that enhance meaning. I love using simple, punchy photos in presentations, because they help what you’re saying resonate in your audience’s mind without pulling their attention from your spoken words. Look for photos that (1) speak strongly to the concept you’re talking about and (2) aren’t compositionally complex. Your photo could be a metaphor or something more literal, but it should be clear why the audience is looking at it, and why it’s paired with what you’re saying. For example, I recently used the image above—a photo of a container ship about to tip over (it eventually sank)—to lead off a co-worker’s deck about failure preparation. And below is another example of a photo I used in a deck to talk about the launch of the new TED.com. The point I was making was that a launch isn’t the end of a project—it’s the beginning of something new. We’ll learn, adapt, change and grow.
