35mm Film - A Short History
By Mark Vurnum
35 mm film - short history.
When it comes to photography and motion picture it is impossible
not to hear about 35 mm. film when going technical into the
conversation. It is called 35 mm. film as it is 35 mm. wide and will
have perforations on both edges at each 4.23 mm along it.
With a history dating back since 1889, when it was first introduced
by Thomas Edison, the 35 mm film is still used today with some
variations in format based on what it is used for but basically its
form stayed the same all these years. It was first introduced into
photography in 1913 and is still very popular amongst several
professional photographers.
If we are to talk about film we have to talk about sound as well. In
the beginning the idea of synchronizing sound and video was
appreciated but was quite difficult to realize. That's when the
sound started to be stored directly to film, forming the analog
soundtrack that takes out of the film a small margin to the left. In
the search for perfection the display ratio changed together with
new methods of storing the sound.
Nowadays digital soundtracks have been implemented. The
technology break through behind this was the storage of the
sound between perforations in Dolby Digital, in 2 strips along the
outside part of the edges in SDDS and lately on a special compact
disk synchronized thanks to a time code with the film in DTS.
With technology evolving as it does at the moment new
techniques and features will probably be available in the future
but so far the main format of the 35 mm film has remained
unchanged with just mild modifications that are better suited for
the purpose it was designed for. The most common aspects of the
film nowadays is considered the one that has 4 perforations, a
vertical pulldown and a density of around one frame in 19 mm.
