Dolly - Netflix

Dolly is an American variety show starring Dolly Parton that aired on ABC from September 27, 1987 to May 10, 1988. The show was an attempt at a traditional variety show, featuring music, comedy skits and various guest stars. It had been roughly a decade since the last successful variety series, The Carol Burnett Show, The Sonny & Cher Comedy Hour and Cher had gone off the air, and it was regarded as a gamble to try to revive the genre. Banking on Parton's talent and appeal, however, ABC paid the performer a reported \$44 million for a two-year contract.

Dolly - Dolly zoom - Netflix

The dolly zoom is an in-camera effect that appears to undermine normal visual perception. The effect is achieved by zooming a zoom lens to adjust the angle of view (often referred to as field of view, or FOV) while the camera dollies (moves) toward or away from the subject in such a way as to keep the subject the same size in the frame throughout. In its classic form, the camera angle is pulled away from a subject while the lens zooms in, or vice versa. Thus, during the zoom, there is a continuous perspective distortion, the most directly noticeable feature being that the background appears to change size relative to the subject. The visual appearance for the viewer is that either the background suddenly grows in size and detail and overwhelms the foreground, or the foreground becomes immense and dominates its previous setting, depending on which way the dolly zoom is executed. As the human visual system uses both size and perspective cues to judge the relative sizes of objects, seeing a perspective change without a size change is a highly unsettling effect, often with strong emotional impact. The effect was first conceived by Irmin Roberts, a Paramount second-unit cameraman, in Alfred Hitchcock's film Vertigo. In addition to Vertigo the shot has been used in many films, including Goodfellas, Road to Perdition, Jaws, Body Double, The Island of Dr. Moreau, and Josie and the Pussycats.

For example, a FOV of 90° and a distance of 2 meters yield a constant width of 4 meters, allowing a 4-meter-wide object to remain still inside the frame during the effect.

distance                =                              width                          2              tan              ⁡                              (                                                                            1                      2                                                                            FOV                                                  )                                                    .              {\displaystyle {\text{distance}}={\frac {\text{width}}{2\tan \left({\frac {1}{2}}{\text{FOV}}\right)}}.}
