The Video Camera Reigns Supreme
The video camera first made its debut in​ the​ television industry but has now penetrated the​ common field .​
BBC (British Broadcasting Company) used the​ first ones in​ the​ 1930`s.
The video camera is​ used mainly for​ two purposes .​
The primary one is​ for​ projection of​ live shows, like the​ ones we see on the​ television as​ also for​ immediate spying as​ used by and​ for​ the​ military and​ industrial operations .​
The second purpose is​ for​ storage and​ archiving .​
Videotapes were at​ one time in​ use but now discs have replaced these.
The latest video cameras (filmadora) are a​ far cry from its first generation models - similarities are difficult to​ trace .​
Professional models of​ video cameras are mobile units and​ allow fine manual control as​ required in​ fieldwork .​
Camcorders (filmadora) are also video cameras - it​ is​ a​ combination of​ a​ camera and​ a​ recording device (VCR) .​
These are in​ great demand for​ home movies, television production, electronic news conferences etc.
Another type of​ video camera is​ the​ closed circuit variety that is​ used for​ security and​ monitoring .​
They are tiny so that can be hidden and​ are often used to​ monitor the​ environment in​ settings where man cannot physically go .​
These web cams are video cameras used where there is​ danger from radiation, excessive heat and​ exposure to​ poisonous chemicals and​ inhospitable terrain.
Another model is​ the​ digital camera that converts the​ signal to​ a​ digital output and​ these are even smaller than the​ security cameras .​
Often these are incorporated into the​ body of​ the​ computer or​ mobile pones and​ laptops .​
Special types of​ video cameras are used abroad satellites for​ probing space or​ inserted in​ robots creating artificial intelligence .​
These come in​ handy also for​ medical use.
Video cameras (filmadora) are slowly taking over the​ film world as​ video technology improves by the​ day .​
Video cameras are now able to​ create special effects like infinite regression - repetition of​ a​ scene.
Video cameras were first meant for​ broadcasting television pictures .​
The first ones were large, mounted on trolleys and​ connected by wires to​ recorders kept in​ another room .​
Technology meant downsizing everything to​ mini handy proportions.
Simultaneously costs began to​ go down making it​ more affordable to​ the​ common people .​
Sales shot up boosting further research in​ the​ field .​
Shoulder operated luggage type video cameras used to​ sell for​ US$1500 .​
Today better features are available from a​ mini model of​ video camera (filmadora) that can rest on the​ palm of​ the​ hand for​ US$150! It is​ a​ revolution in​ evolution.
It consists of​ three parts - the​ lens, the​ imager and​ the​ recorder .​
The lens focuses light on the​ object .​
The imager converts this into video signal and​ then finally it​ is​ stored or​ recorded in​ the​ recorder .​
The camera (filmadora) section consists of​ the​ optics and​ the​ imager .​
The lens has an​ aperture to​ control light, zoom to​ define the​ field of​ vision and​ shutter-speed to​ capture motion in​ continuity .​
The electronics automatically controls and​ adjusts these units.
Professionals have the​ option of​ choosing from models, which have manual functions as​ well so that the​ operator has a​ say in​ the​ matter .​
The imager is​ the​ eye of​ the​ set and​ changes light into video signal electronically .​
The recorder writes the​ video signal on to​ a​ magnetic videotape or​ disc .​
The time and​ date are also recorded.
From ancient times man has been desperate and​ keen to​ capture in​ time what is​ fleeting and​ transitory .​
He has scratched on stone and​ papyrus building library after library of​ life that is​ as​ fleeting as​ the​ moving river .​
This urge still remains .​
With the​ video camera (filmadora) we capture eternally our personal lives and​ record history of​ protests and​ speeches.
