Tilt shift photos are photos of real places but made to look like miniature models. The tilt shift name comes from the optical way of creating the effect. It is when a cameras lens is tilted to make a very shallow depth of field. This effect can also be done through digital photo editing and even phone apps like Instagram can also allow you to acquire the same effect through a phones camera. Check out the tutorial I did on creating tilt shift pictures with Instagram.
