Using a Camera
Video Cameras contain several functions most of which are automated [Focus, anti-shake]
Focus – Every camera needs to focus, sometimes it isn’t visable because it is automated. A video camera can be manually focused by a ring on the lens cover.
White Balance – Means the colour balance, most video cameras automatically use this function however every video camera has the white balance button, this is mainly used when moving from Outdoors to Indoors. [or Indoors to Outdoors]
