The first Photo-livre: the crayon
Wikipedia said about the slowmotion
Slow motion or slowmo is an effect in film-making whereby time appears to be slowed down. It
was invented by Austrian August
Musger. Typically this style is achieved when each film frame is captured at a rate
much faster than it will be played back. When replayed at normal speed, time
appears to be moving more slowly. The technical term for slow motion is
overcranking which refers to the concept of cranking a handcranked camera at a
faster rate than normal (i.e. faster than 24 frames per second). Slow motion can
also be achieved by playing normally recorded footage at a slower speed. This
technique is more often applied to video subjected to instant replay, than to
film. High-speed
photography is a more sophisticated technique that uses specialized
equipment to record fast phenomena, usually for scientific applications.
Slow
motion is ubiquitous in modern filmmaking. It is used by diverse directors to
achieve diverse effects. Some classic subjects of slow motion
include:
Athletic activities of all kinds, to demonstrate skill and style.
To recapture a key moment in an athletic game, typically shown as a replay.
Natural
phenomena, such as a drop of water hitting a glass.
Slow motion can also be
used for artistic effect, to create a romantic or suspenseful aura or to stress
a moment in time. Vsevolod Pudovkin, for
instance, used slow motion in a suicide scene in The Deserter, in which a man
jumping into a river seems sucked down by the slowly splashing waves. Another
example is Face/Off, in which John Woo used
the same technique in the movements of a flock of flying pigeons. The Matrix
made a distinct success in applying the effect into action scenes through the
use of multiple cameras, as well as mixing slow-motion with live action in other
scenes. Japanese director Akira
Kurosawa was a pioneer using this technique in his 1954 movie Seven
Samurai. American director Sam
Peckinpah was another classic lover of the use of slow motion. The technique
is especially associated with explosion effect shots and
underwater footage.The opposite of slow motion is fast motion. Cinematographers refer
to fast motion as undercranking since it was originally achieved by cranking a
handcranked camera slower than normal. It is often used for comic effect, time lapse or occasional
stylistic effect.
The concept of slow motion may have existed before the
invention of the motion picture: the Japanese theatrical form Noh employs very slow
movements.__________________________________
Wikipedia habla sobre el slowmotion
Slow motion o camara lenta es un efecto visual que permite retrasar artificialmente una acción con el fin de aumentar el impacto visual o emocional. La camara lenta se obtiene rodando una escena con un número de imágenes por segundo superior a la velocidad de proyección. Al pasar el registro con un número de imágenes por segundo normal, la escena, más larga, da la impresión de desarrollarse lentamente.
El Austríaco August Musger inventó este método en 1904. Se utiliza generalmente en las películas de cine (en particular, en las escenas románticas, de suspenso o combate), en retransmisiones deportivas para enumerar una acción (objetivo al fútbol, salto de altura, llegada de un curso, etc.) y en aplicaciones científicas (por ejemplo en balística o para estudiar fenómenos naturales dividiendo su formación).
El efecto visual comúnmente llamado Bullet time es una técnica derivada de la camara lenta. Ésta es más compleja de obtener y permite nuevas posibilidades visuales.
La aceleración es la técnica opuesta, que permite aumentar artificialmente la velocidad de una acción o precipitar movimientos
