It is very hard to capture the sheer size of a landscape in a photo, and one trick to do this is the make sure to have an object in your frame that the viewer knows the size of. In the example below you see that the perspective greatly diminishes when I Photoshop my friends out.
The same is true with data in presentations. Putting the stunning image with the word “53 million” on it does not put the size of the number in perspective. Relate it to something instead.
