The Mechanics of CamerasThe IMAGING SENSOR is at the
heart of any digital camera or camcorder
In 3-CCD cameras, light enters the camera lens, passes through a prism and is separated into its three components of Red,
Green and Blue.One CCD or Charge Coupled
Device is devoted to capturing each of the three colors
thereby tripling the potential resolution.
3 CCD Cameras
The Mechanics of Cameras
Single CCD Cameras are usually cheaper and often have a larger
CCD to offset lower inherent resolution. The larger the CCD,
the shallower
the Depth of Field. Our eyes naturally the Depth of Field. Our eyes naturally have shallow depth of field, so larger have shallow depth of field, so larger
CCD’s replicate reality in a more CCD’s replicate reality in a more realistic manner. The largest CCD’s realistic manner. The largest CCD’s
used are about the size of 35mm film used are about the size of 35mm film frames. Therefore, shallow Depth of frames. Therefore, shallow Depth of
Field is generally considered to be Field is generally considered to be more cinematic. more cinematic.
Single CCD Cameras
The Mechanics of Cameras
ResolutionResolutionResolution is measuredin several ways:Horizontal vs. Vertical linesHorizontal vs. Vertical linesA 640x480 image is low resolution while 1920x1080 is A 640x480 image is low resolution while 1920x1080 is HDHD• Size of Imaging SensorSize of Imaging SensorSensors come in ¼, ⅓, ½, ⅔, 1” & 35mm - larger Sensors come in ¼, ⅓, ½, ⅔, 1” & 35mm - larger imagers capture more informationimagers capture more information• Compression Ratio Compression Ratio (compression algorithm)(compression algorithm)To optimize storage, most cameras use compression. To optimize storage, most cameras use compression. TheThelower the compression rate, the higher the resolutionlower the compression rate, the higher the resolution

Overriding the Options
• Manually Control: Setting the Exposure Override the Autofocus Lie to the White Balance Manually Setting the Volume Setting the Zebra Levels Using the Internal ND Filters
