External Mic (Rode VideoMic)

  • Use a dead cat when outside to cut down on wind noise
Holding the Camera
  • Keep elbow tucked, two hands
  • Use support from a wall or table
  • Try to get 3 points of contact for a stable shot 
  • Pan from the waist
  • Watch your wrist!  The pivot point is exactly at your sensor so it’s shaky.
  • Use a tripod whenever possible
Manual Focus / No Zooming
  • Keep a constant distance between camera and subject (Track their steps and pace)
  • Your DOF determines your wiggle room
  • Don’t go below a 2.8 f-stop
