Film is a strip of sequential, still images, taken on photographic film. It is then exposed to light and developed. Video is when audio and visual information is converted into electrical impulses and stored on a magnetic tape, or as a computer file.
A video camera is used to capture moving images and sounds. Light travels through the lens and is reduced to a cone shaped beam.
The charge coupled device receives light from the lens and converts it into digital information. This information will be stored on a tape, a card, or a drive.
Q3 What is the difference between film and video?
Q4 How does information get stored on a storage device that is found within the camera?
Most cameras have a zoom lens. The zoom lenses have a variable focal length that allows objects to appear closer or farther away without changing the lens.
When video taping an object in a studio, we want to have our light source seem as realistic as possible. To do this, we want to use three source lighting.
Key light is your primary source of lighting, and is set on a diagonal.
Fill light helps to minimize the shadows from the Key Light. This light comes in from the opposite diagonal of the Key Light.
Back Light helps to separate the object from the background by providing a gentle glow on the shoulders of the subject.
Q5 What are the three sources of light we want to use when creating a professional looking video?
When video taping in a studio, microphones are typically used and are connected with XLR cables.
Omnidirectional microphones pick up sound in all 360 degrees around the microphone and gives a more natural sound.
Unidirectional microphones typically pick up sounds from a particular area around the microphone, such as when someone is speaking directly into the microphone.
A Lavalier is a small, hands-free microphone that is clipped onto the subject’s clothing.
Q6 When should you use each of the three types of microphones?
How you size or “frame / compose” your subject matter in the camera’s lens depends on the placement of the camera and subject matter and use of the camera’s lens zoom feature. The three basic shot sizes are:
Wide Shot: the entire subject matter is framed in the shot.
Medium Shot: Half of the subject matter is framed in the shot.
Close Up Shot: A part or detail of the subject matter is framed in the shot.
Q7 When would you use each of the three basic shot sizes?
Avoid the natural inclination to center important objects. Instead, divide the shot into three rows and three columns, placing important items on the lines, or the points of intersection.
4 professional techniques to help identify and remove flaws from camera work, and raise production value, are: TRIPOD, STILL, EXPOSURE, and COMPOSITION.
- Tripod:
Flaw: camera work shakes (NO “BLAIR WITCH”)
Solution: use a tripod to record stable images
- Still:
Flaw: camera work in constant motion (again, NO “BLAIR WITCH”!)
Solution: set composition and then lock the pan and tilt bolts on the tripod and do not over zoom
- Exposure:
Flaw: lights or windows in the shot create dark images and silhouettes because of the bright spot in the shot, the Auto Iris function things the entire image is bright and to correct the exposure, darkens the shot
Solution: no lights, windows, doors with windows, skylights or sun in shot – in addition, too much of a light coloured wall, beach or snow will also create this under exposed image – change your camera angle or background to remove light source from image and/or add/utilize studio lighting
- Composition:
Flaw: clutter: elements that are not important to the shot add distraction
background: background is busy, filled with clutter and distractions
merger: strong elements overlap and appear connected (trees, powerlines)
level: horizon line is not level
Solution: remove clutter, select a neutral background, fill screen with subject, do not have major objects behind subject, make sure major reference liens in shot are square to camera frame
