Danke für Euere Erklärungen.
Habe zu "tilt-shift" noch ein kleines Kapitel in der engl. Wikipedia gefunden:

Miniature faking


Miniature simulation using digital post processing


Main article: Miniature faking
Selective focus via tilt is often used to simulate a miniature scene, such that "tilt–shift" came to be used as a general term for any miniature faking technique.
Basic digital post-processing techniques can give results similar to those achieved with tilt, and afford greater flexibility, such as choosing the region that is sharp and the amount of blur for the unsharp regions. Moreover, these choices can be made after the photograph is taken. One advanced technique, Smallgantics, is used for motion-pictures; it was first seen in the 2006 Thom Yorke music video Harrowdown Hill, directed by Chel White. Artist Olivo Barbieri is well known for his miniature-faking stills in the 1990s.
