	Movies - Techniscope

2-Perf or Techniscope is a 35 mm motion picture camera film format. The film has an aspect ratio of 2.39:1 like anamorphic, however it uses two perforations worth of film per frame instead of the four used by anamorphic.

Release prints are made by blowing each frame up by a factor of two vertically. Techniscope has several advantages over CinemaScope:

It uses half as much film as 4-perf and is therefore cheaper.
It uses a cheaper and much less complicated spherical lens.

There are some disadvantages:

Because the film frame is smaller, the enlarged image is grainier; however, some films want this intended look or "feel" for the movie. For example, some of the westerns filmed with this method are in desert plains that have unpolished look or an older look to it enhancing the effects that the movie setting is in the past.
It is difficult to find cameras and telecine facilities for 2-perf.
The very small frame line means that any imperfections, such as hairs in the gate, or lens flares, will be very visible.
