Video Cameras

  1. Use .mp4
  2. if you have adobe bridge, use that. if not, use ImageBrowser EX
  3. Camera work is a combination of technical and aesthetic
    1. Focus – sharp vs. soft
      1. Focal length (length that the light travels to be focused – like a projector)
        1. short – wide angle – picks up a lot at the same time
        2. long – telephoto – capturing a small piece of something (telescope)
        3. zoom
          1. variable (zoom) – You can change length in one continuous move
          2. digital zoom – zoom in even further than you can with optical zoom – artificial.
          3. optical zoom – with the optics of the lens (regular, further level)
        4. A long focal length compresses distance, a short focal length expands distance.
    2. Exposure – light vs. dark
      1. aperture – where light enters
      2. iris – adjusts aperture
      3. the size of the iris is indicated by f/stops (used to be visible on lens, a fraction of the focal length of the lens). The smaller the number the larger the opening is, the larger the number the smaller the aperture is. It spreads the light out so that it is evenly dispersed.
      4. Most cameras have auto-iris that control exposure.Use the auto to find the right exposure, but then lock it.
      5. Shutter – a curtain that pops out of the way and allows the light to come through before closing again. You can have a faster shutter speed,might you need to increase the light (aperture)
      6. ISO – makes the imaging chip more or less sensitive to light. The larger the ISO number the higher light sensitivity and granier.
      7. depth of field: the amount of space that is in focus.
        1. Focal length – longer the lens the shallower the depth of field
        2. Subject distance of Camera – causes a difference in focus between the subject and the surroundings.
        3. Lens aperture
    3. Framing – compose the elements in the frame
      1. shot variation / field of view – getting closer or farther from the subject
      2. camera movement
        1. controlled
          1. requires stabilization device
          2. expensive look
        2. spontaneous
          1. reality TV
          2. move the camera when they don’t have to – energizing the shot
        3. zoom – performed with lens optics
        4. pan – swivel side to side
        5. tilt – tilt camera up and down
        6. dolly – moving camera on a platform, even laterally (used to be called truck but not anymore)
        7. Crane/Jib – raise or lower camera in a fluid way
        8. steadicam – counterweighted harness
      3. Composition
        1. somewhat intuitive
        2. Vectors – lead the eye or orient the viewer
          1.  Types
            1. graphic – lead the eye
            2. index – tell you where things should be coming from. Faces/points a certain way.
            3. motion – tell you where things should be coming from when they are moving
          2. Rules
            1. Line of screen direction – things need to shoot from the same side of this line. Important in storytelling.
            2. Headroom – less than there used to be.
            3. Noseroom and Leadroom – space in front of the subject to balance the shot when someone is looking, pointing or moving across the frame.
            4. Dealing with Motion Axes – Z = moving toward or away from the camera. Z has more energy.
