 Diorama effect using tilt is less effective if a scene includes objects of significant height, such as tall buildings or trees, especially when photographed at a small angle to the ground, because there is a sharpness gradient along surfaces that are obviously the same distance from the camera.Though probably less common, similar difficulties arise if an object has significant extent along the line of sight, such as a long train receding from view, again photographed at a small angle to the ground, because parts of the train that are obviously at considerably different distances from the camera are rendered equally sharp.With a view camera, tilt can usually be set with movements built into the camera; with a small- or medium-format camera, a tilt/shift lens or adapter is usually required.
