its for the camera professinls,indepth details and lpt of pictures.

1. Videography
Video is the technology of electronically
capturing, recording, processing, storing,
transmitting,
and
reconstructing
a
sequence of still images representing
scenes in motion.

2. Videography
The word combines "video" from
Latin, meaning "I see" with the Greek
terminal ending "graphy", meaning "to
write".
 The advent of digital imaging in the late
20th century began to blur the distinction
between videography and
cinematography.

3. videographer
A videographer may be the person
actually operating the Video camera
Or
 he /she may be the person in charge of
the visual design of a production

4. TV Display Basics
The television lights up by thousands of
tiny dots of phosphors with 3 high-energy
beams of electrons.
In most systems, there are three phosphor
colours -- red, green and blue -- which are
evenly distributed on the screen.
By combining these colours in different
proportions, the television can produce the
entire colour spectrum.

5. Understanding TV Camera

6. Electronic Process
Television is an electronic process which
convert light energy into electrical signals
Both TV & film operate by producing a
series of rapidly changing still images, or
Frames to represent motion of the screen.

7. Photoelectric Transducers
It translates or Convert Light (Photo) in to
electrical impulses (electric)
Pickup Tubes and Charge-Coupled
(CCD) are Transducers used in TV
Camera

8. Pickup Tubes and Charge-Coupled (CCD)

9. Charged Coupled Device (CCD)
CCD is an integrated
“chip” that replaces the
pickup tubes in the
Camera
 1st Grid: convert light to
electrical charges
 2nd Grid: hold electrical
charges pattern
 3rd Grid: Amplifies
charges
Charges pattern or video
signal

11. Interlace Scanning

12. Interlacing
In the PAL standard the odd (upper) field
is drawn first and the even (lower) field
second.
 In the NTSC standard, the even (lower)
field is drawn first and the odd (upper) field
second opposite to PAL.
