  • 25. The Mechanics of Cameras
    • The 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
  • 26. 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 have shallow depth of field, so larger CCD’s replicate reality in a more realistic manner. The largest CCD’s used are about the size of 35mm film frames. Therefore, shallow Depth of Field is generally considered to be more cinematic. Single CCD Cameras
  • 27. The Mechanics of Cameras
    • Resolution
    • Resolution is measured
    • in several ways:
    • Horizontal vs. Vertical lines
    • A 640x480 image is low resolution while 1920x1080 is HD
    • Size of Imaging Sensor
    • Sensors come in ¼, ⅓, ½, ⅔, 1” & 35mm - larger imagers capture more information
    • Compression Ratio (compression algorithm)
    • To optimize storage, most cameras use compression. The
    • lower the compression rate, the higher the resolution
  • 28. Filters and Depth of Field
    • Clarifying
    • Diffusion
    • Focus Control
    • Depth of Field
    • Exposure Control
    • Color Modification
  • 29. 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
