VOCAB

2. stands for volume-units: measures volume units, the relative loudness of amplified sound/ there is only one surefire way to know if your camera is recording the audio you want
3. bars a color standard used in video production for the alignment of cameras and recording most higher level video camera and editing software can generate color bars
4. increase in the voltage or power, usually expressed in dB. Gain is a digital camera setting that controls the amplification of the signal, including any associated background noise. Many cameras have automatic gain or autogain which is abbreviated as AGC
9. describes technology that generates ,stores, and processes data in terms of two states: positive and non positive or ones and zeros. Digital video can be copied with no degradation in quality. Unlike traditional video analog video, which is captured frame by frame on a physical tape
11. has the capability to change focal length
13. temperature a scale for measuring the color of available light with warm light in the 2800 to 3400 degree range and cool light on average falling in the range of 5000 to 5600 degrees kelvin.

1. has only one focal length both are typically measured in millimeters
5. of amplification of audio signals
6. balance a color camera function which determines how much red, green and blue is required to produce a normal looking white.shots made with improper white balance will have an abnormal color tint
7. -electronic amplification of a video signal
8. a sequence of images processed electronically into an analog or digital format and displayed on a screen with sufficient rapidity as to create the illusion of motion and continually
10. length the distance from the optical center of the lens to the front surface of the camera imaging device t which the image appears in focus with the lens at infinity
12. Red,Green,Blue which are the primary colors of a digital image. The different colors of light are added together in various to reproduce a broad array of colors
