Similar effects occur in the image of the large, low building; although the miniature simulation of the main subject is reasonable, there are noticeable sharpness differences from top to bottom on the nearest light poles and on the taller building in the background, even though the tops and bottoms of these objects are at nearly the same distances from the camera.

More realistic simulation is possible using more advanced techniques. A simple ''

consisting of a linear gradient can be edited to give uniform sharpness to objects at the same distance from the camera. This effect cannot be achieved using lens tilt.
