“Tilt-shift photography” refers to the use of camera movements on small- and medium-format cameras, and sometimes specifically refers to the use of tilt for selective focus, often for simulating a miniature scene. Sometimes the term is used when the shallow depth of field is simulated with digital post processing; the name may derive from the tilt-shift lens normally required when the effect is produced optically.

In this Thursday, May 8, 2014 photo, guests look down from the Tilt!, a new tourist attraction that provides guests a unique view of the downtown area from the 94th floor of the John Hancock Building, after it was unveiled in Chicago. People hold onto handrails as the glass and steel facade tilts forward 30 degrees. (Photo by Ashlee Rezin/AP Photo/Sun-Times Media)

In this Wednesday, March 18, 2015 photo, limestone quarry workers walk through a cloud of dust spewed into the air by rotor blades of the stone-cutting machinery in the desert of Minya, southern Egypt. Around 45,000 people, including children, work in an estimated 1,500 quarries, digging out stones that later will be used in construction or powdered to be used by pharmaceutical and ceramic companies.

Lean with it' is a photographic series by chicago-based artist Paul Octavious. The images catalog friends of the photographer tilting their bodies along the same angle as a slanted tree, capturing the scene in different seasons.

Maj. Matt O'Donnell of Glenelg, MD shields himself from rotor wash as Ospreys carrying the delegation of U.S. Secretary of Defense Leon Panetta leaves on March 14, 2012 at Forward Operating Base Shukvani, Afghanistan. Panetta is also scheduled to meet with President Karzai during his two-day visit to Afghanistan. The trip comes as the Taliban has vowed revenge following this past weekend's killing spree by a U.S. soldier who is accused of killing 16 civilians in Afghanistan. Most of those killed were children and women. (Photo by Scott Olson/Getty Images)

Barking mad owners have proved they really do look like their pets – by performing impressions of their own dogs. In a series of hilarious “paw”-traits, owners pull their best faces to look like their pooches. Snapped by photographer Ines Opifanti, people stuck their tongues out, yawned and tilted their heads in curiosity at the camera. Opifanti, from Hamburg, Germany, came up with the idea while interacting with her own dogs, two pug/French bulldog crossbreeds. Here: Amina and Zazou the dog. (Photo by Ines Opifanti/Caters News)

Toyota revealed its i-Road concept, a three-wheeled all-electric motorcycle of sorts that seats two. The unique design is only 33 inches wide, which would make it tops in buzzing in through and around traffic. An Active Lean system tilts the i-Road through corners like a motorbike, while the cabin (which seats two in a tandem layout) is fully enclosed. Maximum range is about 30 miles.

In this photo submitted by the Washington Post tilted “The Moment Time Stopped”, survivors piled bodies of the dead outside for weeks after earthquake on January 14, 2010 in Port-au-Prince, Haiti. The 7.0 magnitude earthquake struck in 2010, and the Haitian government has said more than 300,000 people were killed. The exact toll is unknown because there was no systematic effort to count bodies among the chaos and destruction. (Photo by Carol Guzy/AP Photo/The Washington Post)
