, and Kodak never manufactured nitrate film for the format due to the high flammability of the nitrate base. 35 mm nitrate was discontinued in 1952.

Production evolution

The silent 16 mm format was initially aimed at the home enthusiast, but by the 1930s it had begun to make inroads into the educational market. The addition of optical sound tracks and, most notably, Kodachrome in 1935, gave an enormous boost to the 16 mm market. Used extensively in WW2, there was a huge expansion of 16 mm professional filmmaking in the post-war years. Films for government, business, medical and industrial clients created a large network of 16 mm professional filmmakers and related service industries in the 1950s and 1960s. The advent of television production also enhanced the use of 16 mm film, initially for its advantage of cost and portability over 35 mm. At first used as a news-gathering format, the 16 mm format was also used to create television program

 video tape has made significant inroads in television production use, even to the extent that in some countries, 16 mm is considered obsolete as a TV production format by broadcasters. Nevertheless, it is still in extensive use in its Super 16 ratio (see below) for high-quality programming in the US and UK. Independently produced documentaries and shorts (intended mainly for TV use) may still be shot on film. Furthermore television documentary film-makers will frequently use clockwork 16 mm cameras to shoot scenes in extreme climates.

Super 16 mm

The variant called Super 16 mm, Super 16, or 16 mm Type W uses single-sprocket film, and takes advantage of the extra room for an expanded picture area of 7.41 mm by 12.52 mm with a wider aspect ratio of 1.67.

Ultra 16 mm

A variation of the Super 16 format is the DIY-crafted "Ultra-16", which is formed by widening the gate of a standard 16 mm camera to expose the area between the perforations. The placement of the perforations on a standard strip of 16 mm film (to the left of the division between frames) allows for use of this normally unexposed area. The Ultra-16 format, with frame dimensions of 11.66 mm by 6.15 mm, allows for a frame size between those of standard 16 mm and Super 16 while avoiding the expense of converting a 16 mm camera to Super 16, the lens requirements of Super 16 cameras, and the image vignetting
Vignetting

 caused by traditional 16 mm cameras. Thus, standard 16 mm optics may be used to achieve a wider image. The image readily converts to NTSC/PAL (1.33 ratio), HDTV (1.78 ratio) and to 35 mm film (1.85 ratio), using either both the full vertical frame or the full width (intersprocket) frame, depending upon application.

Film reproduction methods

In most original film production, movies are shot on 35 mm. The 35 mm size must be converted or reduced to 16 mm for use in 16 mm systems. There are multiple ways of obtaining a 16mm print from 35 mm. The preferred method is to strike a 16mm negative from the original 35 mm negative and then make a print from the new 16 mm negative. If a 16 mm negative is struck from the original 35 mm negative, it is called an "original". If a new 16 mm print is made from a print with no negative it is called a "reversal".
16 mm prints can also be made from many combinations of size and format, each with its own distinct and descriptive name as follows:
  • If a 16 mm negative is struck from an original 35 mm print, it is called a "Print Down".
  • If a 16 mm negative is struck from an original 16 mm print struck from a 35mm original print, it is called a "Dupe Down".
  • If a 16 mm print is struck directly from a 16 mm print, it is called a "Double Dupe".
  • If a 16 mm print is struck directly from a 35 mm print, it is called a "Double Dupe Down".


When film traders buy and sell 16 mm prints they often refer to the print through its production method, that is an "original", "reversal", "dupe down", "double dupe", and "double dupe down".

Color fading of old film and color recovery

Over a period of many decades, the pigments in color 16mm film slowly degrade and become transparent. The pigments degrade at different rates with magenta being the longest-lasting. This inevitably results in color film that now appears to be reddish, with few other colors. This was especially noticeable on many pre-2000 video releases of color Warner Bros.
