light there is nothing except for sound. It is where video starts.
source bounces off an object, goes though the camera lens, onto the
CCD and then is recorded onto the tape. The less light you have, the
less information bounces off the object through the lens to the CCD,
making your picture feel grainy because there is less information
recorded. The more light you have, the more information there is for
the camera to pick up making the picture more vibrant and clear.
thinking about light, there are 5 major areas to consider.
The Lighting Source
This is generally what you start with to illuminate objects in the
scene. There are a variety of different types of lights to choose
from: box lights, condecent lights, incandescent lights, spot lights
and the list goes on.
The object that reflects light into the camera can dull or shinny,
dark or light. These different variables need to be factored when
setting up your lighting source.
The size of the lens, the amount the shutter opens, and the frequency
in which the shutter opens all can contribute to how much light is
necessary for a shot.
The CCD(Charged Coupling Device) converts light waves into digital
signals. Some cameras have larger CCD's with higher resolutions. Some
camera's have separate CCD's to specifically handle certain colors(red,
green and blue). Not all CCD's are created equal, some are more sensitive
than others having better signal to noise ratios.
The Ambient Light
Ambient light comes in many colors and can effect what the camera
sees. It is created by the reflected light mixing together in a room.
For instance, if the carpet is red, objects may take on a slight red
can chance in different areas of space. (More coming soon)
