For those who don’t know, cartography is the making of maps. The word comes from the french terms carte and -graphie, which literally mean map and writing. Daniel Boschung is a face cartographer, and he does exactly what that title suggests: he makes geographic landscapes out of portraits of the human face.
The maximum resolution of a perfect human eye is around 450 pixels per inch (PPI). That means if you’ve got a smartphone, like the iPhone 5S, you probably wouldn’t notice the separate tiny pixels that make up the screen because of its display of 326 PPI. The screen looks almost as sharp as real life. Keeping that in mind, if you were to take a 90 x 90 inch portrait of one of the faces photographed by Daniel Boschung in this project, the final resolution of the picture would amount to somewhere at 111,000 PPI.
