Cards

Term
Three stages of production
Definition

1. Pre-production

2. Production

3. Post-production

Term
Steps in a camera. Light comes in then...
Definition

1. Hits beam splitter

2. Split into red, green, blue

3. Sent to CCD's (one for each color)

4. CCDs transduct (change energy from light to electronic signal.)

Term
3 layers of CCD
Definition
Light sensitive grid, storage grid and output grid.
Term
Progressive scanning
Definition
Scans all the lines sequentially
Term
Interlaced scanning
Definition
Scans all odd # lines, back to top then scans all even # lines
Term
5 parts of digital transition
Definition

1. Aspect ratio from 3x4 to 9x16

2. Switch to sampling for signal copying (vs. analog)

3. Digital uses binary code to store info

4. Frame rate changed

5. Lines of resolution increased (except for 480, that stayed below the normal 525.)

Term

Short lens

1. also known as

2. What field of view

3. Zoomed in or out?

Definition

1. Short focal length

2. Wide field of view

3. Zoomed out

Term

Long Lens

1. a.k.a.

2. What kind of field of view?

3. Zoomed in or out?

Definition

1. Long focal length

2. Narrow field of view

3. Zoomed in

Term

F-stop

1. Refers to...

2. f/x. If x is smaller, how much light in? X is bigger, how much light in?

Definition

1. Aperture (how much light is let in)

2. Bigger x is, less light is let in.

Term
Aperture
Definition
How much light is let in lens.
Term

Depth of field

1. What is it?

2. Depends on?

Definition

1. The area of which all objects, located at different distances from the camera, appear in focus. 

2. Depends on f-stop, focal length of lens, and distance from camera to the object.

Term
Keys to framing
Definition
Allow for nose room and head room
Term
Analog signal
Definition
Electronic copy of signal
Term
Digital signal
Definition
Discontinuous signal by sampling
Term
Frame rate
Definition
How long it takes to scan a complete frame
Term
Sampling
Definition
Samples are taken off the analog and Quantized into 0s and 1s.
Term
Field
Definition
One half of a scanning cycle, or frame.
Term
Compression
Definition
Eliminates data off signal that doesn't need to be preserved.
Term
Lens speed
Definition
How much light can get through a lens. Fast lens is more light, slow lens less light.
Term
Lens iris and aperature
Definition
Iris controls how much light is transmitted. Aperture is the adjustable hole that controls the amount of light, and it can be "closed down" in well-lit scenes.
Term
Optical zoom vs. digital zoom
Definition
Optical doesn't affect quality of image, digital gets fuzzy because the image is just being magnified.
Term
Four parts of camera chain
Definition

1. Camera

2. Power supply

3. Sync generator

4. CCU (camera control unit.)

Term
Pan
Definition
Horizontal movement
Term
Tilt
Definition
Vertical movement
Term
Cant
Definition
Tilt camera sideways
Term
Pedestal
Definition
Elevate or lower camera on tripod
Term
Dolly
Definition
Move toward or away from object
Term
Truck
Definition
Move camera laterally
Term
Crane
Definition
Move the camera up or down on a crane or jib
Term
How to calibrate zoom lens
Definition
Zoom in as far as possible, focus
Term
Shutter speed
Definition
Higher shutter speed, higher amount of light needed
Term
Standard T.V. ratio
Definition
3x4
Term
HDTV ratio
Definition
9x16
Term
Five camera shots (describes field of view)
Definition

1. Extreme long shot

2. Long shot

3. Medium shot

4. Close up

5. Extreme close up

Term
Vector
Definition
Camera shot that creates direction that the eye moves through the shot
Term
3 kinds of vectors
Definition

1. Graphic vector: Stationary objects create direction

2. Index vector: Something unquestionably points in a direction.

3. Motion vector: Something moves in a direction on screen.

Term
Pickup pattern
Definition
Area a mic can hear well
Term
3 pickup patterns
Definition
Omnidirectional, cardioid and hypercardioid
Term
Cardioid mics
Definition
Hears well in one direction
Term
Omnidirectional mics
Definition
hears well in all directions
Term
Hypercardioid mics
Definition
Have a long reach
Term
3 construction types of mics
Definition
Dynamic, condensor and ribbon
Term
Dynamic mic
Definition
Rugged. Can work with loud sounds
Term
Condensor mic
Definition
Higher quality sounds, more sensitive than dynamic
Term
Ribbon mic
Definition
High quality and very sensitive
Term
Lavalier mic
Definition
Clip on mic
Term
Sweetening (sound)
Definition
Post production elimination of unwanted sounds or adding wanted sounds.
Term
5 purposes of audio boards
