Swiss photographer Roger Eberhard is wondering “why do we travel the world and stay in a place that looks same everywhere we go? What does that say about us as creatures of habit?" For his new photo book, Standard, the Swiss photographer traveled to 32 countries across six continents and always stayed for one night at a Hilton Hotel. “His documentation was always the same—one photo captured the interior of his Hilton hotel room, and another the view out of his window,” Meg Miller writes for Fast Codesign. “To flip from hotel room to hotel room in Standard is to find the design and layout of each room to be eerily uniform. This is by design,” Miller writes. Eberhard noticed that, while all the rooms were abiding by the Hilton Design and Construction Standards Manual, they each had slight changes in decor that alluded to the locale. Miller’s piece includes a slideshow of some of the rooms Eberhard spent time in.
