sedikit penjelasan ttg film 35mm:

35 mm film is the basic film gauge most commonly used for chemical still photography (see 135 film) and motion pictures, and remains relatively unchanged since its introduction in 1892 by William Dickson and Thomas Edison, using film stock supplied by George Eastman. The photographic film is cut into strips 35 millimeters (about 1 3/8 inches) wide—hence the name.[1][2] The standard negative pulldown for movies ("single-frame" format) is four perforations per frame along both edges, which makes for exactly 16 frames per foot[3] (for stills, the standard frame is eight perforations).

A wide variety of largely proprietary gauges were used by the numerous camera and projection systems invented independently in the late 19th century and early 20th century, ranging from 13 mm to 75 mm (0.51–2.95 in).[4] 35 mm was eventually recognized as the international standard gauge in 1909,[5] and has remained by far the dominant film gauge for image origination and projection despite challenges from smaller and larger gauges, and from novel formats, because its size allows for a relatively good tradeoff between the cost of the film stock and the quality of the images captured. The ubiquity of 35 mm movie projectors in commercial movie theaters makes it the only motion picture format, film or video, that can be played in almost any cinema in the world.

The gauge is remarkably versatile in application. In the past one hundred years, it has been modified to include sound, redesigned to create a safer film base, formulated to capture color, has accommodated a bevy of widescreen formats, and has incorporated digital sound data into nearly all of its non-frame areas. Since the mid-1990s, Eastman Kodak and Fujifilm have held a duopoly in the manufacture of 35 mm motion picture negative film. However print film continues to be offered for sale by Agfa-Gavaert (a maker of Aerial films split off from Agfa Photo before the latter's insolvency), as well as Lucky Films in China.

The 120 format is typical of roll film. The spool was originally made of wood with metal flanges, later all metal, and finally plastic. The film is at least 30 inches (76 cm) long, up to 32–33 inches (81–84 cm),[1] attached to a piece of backing paper longer and slightly wider than the film. The backing paper protects the film while it is wound on the spool, with enough extra length to allow loading and unloading the roll in daylight without exposing any of the film. Frame number markings for the three standard image formats (6×4.5, 6×6, and 6×9; see below) are printed on the backing paper.
The 220 format was introduced in 1965 and is the same width as 120 film, but with about double the length of film and thus twice the number of possible exposures per roll. Unlike 120 film, however, there is no backing paper behind the film itself, just a leader and a trailer. This results in a longer film on the same spool, but there are no printed frame numbers. Moreover, it cannot be used in unmodified old cameras that have a red window as frame indicator. Also, since the film alone is thinner than a film with a backing paper, a special pressure plate may be required to achieve optimal focus if the film is registered against its back side. Some cameras capable of using both 120 and 220 film will have a two position adjustment of the pressure plate (e.g. the Mamiya C220 or Mamiya C330) while others will require different film backs e.g. the Pentax 645 or Kowa Six).
The specifications for 120 and 220 film are defined in the ISO 732 standard. Earlier editions of ISO 732 also provided international standards for the now-obsolete 127 and 620 film formats.
