When we think about all of the visual graphs in regards to how a lens' apertures work, there are literal drawings of them. But photographer Nick de Bruijn came up with a special way of explaining how they work simply by using and carefully arranging the lenses themselves.
As you can in the image above, the lenses are arranged from top to bottom from 1. 2 to f3. 5. The way that one is supposed to think about this is the largest aperture is on top (and therefore less closed down) and then smallest is on the bottom. Of course, that all depends on the maximum aperture of the lens--but if you think about the size of this all being in regards to a single lens, then you'll see how genius this all is. . thephoblographer.com
