Practical uses[edit]
Cinemascope, Panavision, Technirama and other widescreen formats use anamorphosis to project a wider image from a narrower film frame.
The system of anamorphic projection can be seen quite commonly on text written at a very flat angle on roadways, such as "Bus Lane" or "Children Crossing", which is easily read by drivers who otherwise would have difficulty reading as the vehicle approaches the text; when the vehicle is nearly above the text, its true abnormally elongated shape can be seen. Similarly, in many sporting stadiums, especially in Rugby football in Australia, it is used to promote company brands which are painted onto the playing surface; from the television camera angle, the writing appear as signs standing vertically within the field of play.
On some 0.5 liter Sprite bottles in Europe, an extra "bar code" was present. When the bottle is tilted towards the mouth while drinking, the bar code resolves into writing due to the anamorphic effect.[citation needed]
Much writing on shop windows is in origin anamorphic, as it was written mirror-reversed on the inside of the window glass.
