There were many
contributors to the growth of television and therefore not one single person
can claim ownership of the whole process. Its invention and later development
spans over along period of like 100 years as noted by Porter and Duff (1988).
However its development and later improvement is attributable to Vladimir Zworykin and Philo Farnesworth spanning the late 1880’s
and late 1980’s. They made major contributions both the picture and sound
effects.
Visual
effects refer to the many processes by which an image can be made to look even
better outside the live action shooting. The visual basics used
in films and in television are mostly similar. In order
to create environments that look real, computer generated images (CGI) and what
is captured in the live act is combined to create pictures as explained by Mayur
(2009). This is especially used by the huge-capital film producers as it is costly
and capital intensive. However the small industry players can use the computer
to generate animated films. It is also possible to use a soft ware for
compositing to make a film. Though the live part of the film is only possible
with CGI, poor quality and easy films can be made that way (Mayur, 2009).
Initial
stages of film and television production require live action that is recorded
in lenses, film stocks, projectors and cameras. These image sources are
combined with sound sources, transmitters and receivers to form the desired
final product (Rickitt, 2007). The image source can be a person or an object,
the sound source can be someone speaking or the sound of anything, lenses are
cameras and screens are monitors of computers or television screens. Television
however has a way it transmits its signals differently from films (Shilo, 2007). Using transmitters from the ground you can be
able to receive images from a TV set. The discovery of both influenced the
other. The scientist that came across TV was experimenting with making films
from cameras. However film was created first and influenced television making.
