INTRODUCTION
The first movie was made over a 100 years back. Itwas rudimentary, short, devoid of any audio andbasically very dull and boring. Movie technology
has improved by heaps and bounds. Movies thesedays stimulate our minds and take us into a wholenew world. I bet not one of you will disagree of howsimply fabulous the movie Avatar was thanks to
the special effects. It introduced us to a whole newgenre of movie making. Let us trace this trajectoryand see how we reached this advanced a stage of
movie making today.

In the yr 1892 the Lumire brothers started creating
moving picturesThe Lumires held their first private screening of projected
motion pictures in 1895 in Paris.
Their first film was Sortie des Usines Lumire Lyon which means (Workers Leaving the Lumire Factory).
Their work in this field spread unbelievably. Then they
turned their attentions to color photography and in 1903they patented a color photography process, the"Autochrome Lumire", launched on the market in 1907.

Dhundiraj Govind Phalke, popularly known
as Dadasaheb Phalke (30 April 1870 - 16 February1944) was an Indian producer-director-screenwriter, known as the father ofIndian cinema.
He was the first person to start the concept ofmovies in India,with this he came up with his first
debut film raja harishchandra in 1912 which isknown as India's first full-length feature, effectivelymarking the beginning of the Indian film industry.
The Dadasaheb Phalke Award for lifetimecontribution to cinema, was instituted in his honor,
by Government of India in 1969, and is the mostprestigious and coveted award in Indian Cinema
Phalke formed a film company, Hindustan Films .

The Lumire brothers came into picture and invented the firstmotion picture camera in 1895. He invented cinematograph.
In 1895s movies there was no editing n mixing, they were shot
films or cinematic techniques.
19th century marked the beginning of silent films but by the early1920s, most films came with a prepared list of sheet music for thispurpose, which were black and white.
The next development in this field was the introduction ofnatural color. Color television had been available in the US sincethe mid-1950s which gained popularity since then.
Then around 1980s and 1990s 3d movies started gainingpopularity. In the 20th century animation entered in the field of
movie technology which gained and is still gaining lot ofappreciation.

Sound synchronization CMost film cameras do not record
sound internally; instead, the sound is
captured separately by a precisionaudio device (double-systemrecording). The exceptions to this arethe single-system news film cameras,
which had either an opticalor latermagnetic recording head inside thecamera.
Double-system cameras are generallycategorized as either "sync" or "non-sync."Sync cameras use crystal-controlled motors that ensure that film
is advanced through the camera at aprecise speed while Non-sync or

ent Cinematography can not only depict a
moving subject but can use a camera,
which represents the audience'sviewpoint or perspective, that movesduring the course of filming. Thismovement plays a considerable role inthe emotional language of film imagesand the audience's emotional reaction to
the action. Techniques range from themost basic movements of panning, tiltingto dollying, craning and combinations ofthe above.

WHAT ARE SPECIAL EFFECTS
Special Effects is both an art and a
science.The "science" part involves thecomplete understanding of how theaudio-visual sensory parts of ourbody and brain perceive the world
around us, while the "art" partinvolves the strategic use of thisinformation to fool the sensorysystem.

In Hollywood today, some of the highest revenue producing
movies have been 3D animation films. The latest of them to hit
the box-office is the often touted movie Avatar.
There have been many other 3D movies that were embraced by
the public in a very large way also. There is Toy Story I and II,

PROCESS OF ANIMATION
There are four major parts to make an animation:
Development of ideas and story: First of all, there must be an idea to base
the animation on. When an idea is developed, the characters and stories are
further explored and expanded upon
Sketching and Drawings: draw the keyframes of the animation. Keyframes
are significant scenes in the story that shows the essential actions that lead to
the development of the story
Putting it all together: all the cels and pieces of art are compiled together and
screened. by scanning the different pages and then put them together to form
the movie. At this stage the sound and music of the animation is also recordedto match the pictures perfectly
Editing: Finally, the film is now edited carefully and final touches
are made to make sure it has the maximum effect.

TYPES OF ANIMATION
There are many different types of animation that are used in our present day world.
The three main ones are
1. Computer animation2. Stop-motion animation
3. Clay animation
The most common type of animation is drawn on cells and is 2-D.
Later the 3-D(three-dimensional) animation of clay animation is created. Andrecently, the most popular type of animation is computer animation.

TYPES OF ANIMATION
Computer Animation
In the late 20th century, with the help of computer generated
graphics, movies such as the Star Wars Trilogy and the Jurassic
Park (directed by George Lucas and Spielberg respectively) have
been created. In these two movies, much of the ComputerGenerated Imaging (CGI) was used to create impressive scenes
that would otherwise need to waste much money on building
believable models and then filming them. The use of computers
also came in where dangerous stunts need to be done.

TYPES OF ANIMATION
Stop-motion animation
Stop-motion animation, is simply a way to
animate puppets. Essentially, puppets areused and a photograph is taken every time
their position is changed slightly to create a
fluid-like motion
Stop motion animation has a long history in
film. It was often used to show objectsmoving as if by magic. The first instance of
the stop motion technique can be seen in The
Humpty Dumpty Circus(1897), in which a toy
circus of acrobats and animals come to life.
The textures achieved with CGI cannot match the way real textures captured by stopmotion and this is proved by Tim Burton, in his puppet-animated film Corpse
Bride which was released in 2005.
Along with movies, stop motion animation is used in many projects such as in
children's programming, as well as in commercials and comic shows such as Robot
Chicken.

TYPES OF ANIMATION
Clay animation
Clay animation is sometimes called 3-D animation
because the figures are 3-D on a 3-D set. Clay animationis where you make something out of clay and move it so
it is slightly different in every frame and take a picture, a
lot like regular animation.
Unlike regular animation, in clay animation, instead of
drawing a figure in different positions, you make the clayfigure it different positions. One of the most popular clay
animations we see are from Aardman Animations, such as
Wallace and Grommit.

ANIMATRONICS
Animatronics is the use of mechatronics to create machines
which seem animate rather than robotic. Animatronic creations
include animals (including dinosaurs), plants and even mythical
creatures. A robot designed to be a convincing imitation of a
human is specifically known as an android. Animatronics is mainly used in movie making, but also in theme
parks and other forms of entertainment.
Its main advantage over CGI and stop motion is that the
simulated creature has a physical presence moving in front of
the camera in real time. Animatronics is used in situations where the creatures does not
exist; the action is too risky or costly to use real actors or
animals; or the action could never be obtained with a living
person or animal.

PHYSICS AND MECHANISM OF
3D MOVIES
The technology allows 2 images of the same scene to be
superimposed with each other, in order to create an
illusion of depth. Moviegoers are given special glasses
with filters to help them perceive these two perspectivesas one complete image with depth. It is our brain which
analyzes the two images instantly and perceives them as a
three dimensional object.

TECHNICAL PROGRESS OF 3D MOVIES
The stereoscopic era of motion pictures began in the
late 1890s when British film pioneerWilliam Friese-
Greene filed a patent for a 3-D movie process. In the
late 19th and early 20th Centuries the dominanttechnology to arise in this era was stereoscopic 3D.

1885- In 1855 the Kinematascope, a stereo animation camera,was invented. It was able to create 3d motion pictures.
1915- In 1915 the first anaglyph movie was produced.Anaglyph technology used 3d glasses with 2 different colorlenses that would direct an image to each eye.
1950-filmmakers used to use color filtersto divide the film into two separate images.
The left film is passed through a blue
filter and the right film is passed through
the red. Two projectors would project
these images together .glasses are used
for viewing purpose.
1960- In the 1960s a new technology called Space-Vision 3Dwas released

1970- In 1970, Stereovision technology was developed.
1980- In the early 1980s many movies were released in3D using the process of Space Vision.
1986- In the mid 1980s IMAX began producingdocumentary films in 3D. IMAXs 3D technologyemphasized mathematical correctness and this eliminatedthe eye fatigue that was seen in previous 3D technologies.
2003- In 2003, James Cameron released Ghosts of theAbyss. This was the first full length 3D IMAX featurefilm. This movie used the latest IMAX
3D technology called Reality Camera System.

IMAX The IMAX 3D process uses separate camera lenses separated by an intraocular
distance of 64 mm (2.5 in), the average distance between a human's eyes. Each lens
feeds a separate roll of film. By projecting the two films simultaneously, viewers
experience seeing a 3D image on 2D screen.
One method of creating the 3D illusion involves polarization of the light from thetwo images.
Alternatively the two projectors take turns displaying each frame at an effective rate
of 48 frames per second. The viewer dons LCD shutter glasses that contain LCD
panels that block or emit light in each eye in sync with the projector, such that each
eye only sees the image intended for it.

REAL D
RealD 3D cinemas uses circular polarized plasticglasses instead of linear polarized to provide betteruser experience when watching stereoscopic content.
This technology requires the use of more expensivesilver screen for projection which makes it a bit moreexpensive to implement.

An alternate color wheel is placed in the projector. This color
wheel contains one more set of red, green, and blue filters in
addition to the red, green, and blue filters found on a typical
color wheel. The additional set of three filters are able to
produce the same color gamut as the original three filters, but
transmit light at different wavelengths. In this way, one
projector can display the left and right stereoscopic images
simultaneously. This method of stereoscopic projection is
called wavelength multiplex visualization

DIGITAL RELIEF
Filmmakers now use computers to determineinteraxial distance and ZPS and to align cameras.
Two film projectors were once required to show 3D,theaters can now use a single digital projector outfittedwith a photo-optical device; theaters are in the processof replacing analog projectors with digital ones.
Today, filmmakers use circular polarization, whichretains 3D fusion while allowing audience members tomove their heads.

What is 4D?
Adding another dimension to 3D.
Physical movement gives 4D.
This happens with the movement ofthe chairs that you sit on.
It makes you feel that you are in the
same place where the event occurs.

Experiencing 4D
Some of the effects you see in 3D
movies are simulated in real time
in the theatres for 4D.
For example, wind, rain, and
vibrations are simulated to give the
viewers the real experience of
being in the centre of whathappens in the movie.

The editor must create:
Spatial relationships between shots
Temporal relationships between shots: flashback,flash-forward, ellipsis
Montage (Fr. editing) is a condensed series of imagesthat shows us a series of events
Duration and rhythm - the length of time you look ata shot; the tempo of the film (leisurely or fast?). Thetempo of edits can be increased/decreased to speedup or slow down a viewers perception of time.

Continuity-creating shots
Master shot - orients the viewer, sets the scene; may be shot from
different angles; establishes the scene
Screen direction/180 rule/axis of action- the direction in which a
figure moves on the screen. The 180-degree rule or axis of action -
a hypothetical line that keeps the action on a single side of the
camera.
Shot/reverse shot - Reverse-angle shots are permitted as long as
everything is kept continuous.

WHY DOMES???
The human eye provides a field-of-view ofabout 200 horizontal x 130 vertical.
Dome screens are large enough to fill your
entire field of vision.Thus the screen gives you an incredible
feeling of immersion and it also enhancesthe feeling of motion.
In fact, the feeling of motion is so strong thatit makes some people ill.!!

WHY DOMES??? Domes also presentimages which arerendered to a view spherethan a view plane.
Modern scientists haveadopted a spherical modelof our visual field to
explain wide-angle vision. Thus spherical domes
reproduce a more naturallooking image with anunlimited number of
vanishing points in alldirections.!

To present a stereoscopic motion picture, two imagesare projected superimposed onto the same screenthrough different polarizing filters. As each filterpasses only that light which is similarly polarized and
blocks the light polarized differently, each eye sees adifferent image.

Colored filters cover each eye, red/green, red/blue orred/cyan filters being the most common. One eye
image is displayed in red and the other in green, blue orcyan so that the appropriate eye sees the correct image.Since both images appear
simultaneously, it is a time-parallel method.

With the eclipse method, a mechanical shutter blockslight from each appropriate eye when the converseeye's image is projected on the screen. The projectoralternates between left and right images, and opens
and closes the shutters in the glasses or viewer insynchronization with the images on the screen.

Lenticular printing and parallax barrier technologiesinvolve imposing two (or more) images on the samesheet, in narrow, alternating strips, and using a screen
that either blocks one of the two images' strips (in thecase of parallax barriers) or uses equally narrow lensesto bend the strips of image and make it appear to fillthe entire image (in the case of lenticular prints).

There is increasing emergence ofnew 3-D viewing systems which donot require the use of specialviewing glasses. These systems arereferred to as Autostereoscopic
displays. They were initiallydeveloped by Sharp. The firstAutostereoscopic LCD displaysfirst appeared on the Sharp ActiusRD3D notebook and the first LCD
monitor was shipped by Sharp in2004 for the professional market.
