"Tilt-shift photography is a creative and unique type of photography in which the camera is manipulated so that a life-sized location or subject looks like a miniature-scale model."
"To add good miniature effect to your photographs, shoot subjects from a high angle (especially from the air). It creates the illusion of looking down at a miniature model. A camera equipped with a tilt-shift lens, which simulates a shallow depth of field, is essentially all you need to start."
