Electronic Media Flashcards
Define focal point
point where light rays converge
Define iris
A hole that opens and closes to allow in different amounts of light (measured in F-stops and also called Aperture).
Define tripod
A three legged stand to hold a camera steady
Define CCD
This is the sensor (I think).
Define depth of field
the area in front of and behind your subject along the Z axis that remains in focus
Define focal plane
the plane where the focused image appears
What appearances do different camera angles give?
High angle shot gives appearance of smallness and vulnerability. Low angle gives appearance of strength.
Have an understanding about the differences in standard vs. high definition video.
SD is mostly square while HD is more rectangle.
The biggest difference is the resolution.
SD = 480
HD = 720 & 1080
Ultra HD = 4k & 5k
What are the four raw file formats for audio and video?
Windows: AVI (video), WAV (audio)
Mac: MOV (video), AIFF (audio)
What is the rule of thirds?
A rule commonly used in photography, but can be good in video too which says that a subject will appear more interesting if lined up with certain lines on a grid. It is also good to have the subject leaning/looking in to the frame.
Define sound
vibration of air molecules
Define amplitude
better known as volume, amplitude is the physical hight of a sound wave.
What is amplitude measured in?
decibels
Define cycle (relating to sound)
one complete vibration, normal to high to low to normal
Define frequency
number of cycles per second, determines pitch, measured in Hertz
