FMTV 110 Basic Cinematography Final
what is the conversion of watts to amps?
100 watts = 0.84 amp (+/- 1 amp)
how does white balance change with higher "temperature"?
bluer colors are higher number, warm colors are lower numbers
what is the "vertigo" shot?
change in depth of field during the shot by compressing space on the z axis
a fresnel lens is a series of ________ in a flat lens
concentric rings
how is the "vertigo" shot created?
dolly back while zooming in at the same time
open-faced lights
fixture has a lamp which sits in front of the reflector, generally without a focusing beam and light diffusion (ex. lowel 500 watt, arrilite 750 watt)
what four factors affect depth of field?
focal length, distance, aperture, sensor size
are fresnel lights hard or soft?
fresnel lights are soft
how does sensor size affect depth of field?
large sensors (full frame) will create shallower depth of field than smaller sensor (M4/3)
what is a prime lens?
lens with a fixed focal length
what is a zoom lens?
lens without a fixed focal length
what are elements of mise en scene?
lighting and camera, costume/hair/makeup, blocking and expression, setting, set and production design, props
are open-faced lights hard or soft?
open-faced lights are hard
what is the difference between a prime and zoom lens?
prime lenses have a fixed focal length, zoom lenses do not
define ISO
sensitivity to light
what does putting the camera at a high-angle do?
shows weakness or makes the subject seem small
how does focal length affect depth of field?
telephoto (long lens) creates shallow depth of field, wide angle (short lens) creates deeper depth of field
how does distance affect depth of field?
the closer the lens to the subject, the less depth of field (ex. bringing an item closer to the camera and seeing only that in focus)
what is focal length?
the distance from the center of the lens to the principal focus
what is mise en scene?
the overall look and feel, "the action of putting on to the stage"
what is white balance?
white balance changes the color of an image depending on the color temperature
lens focal lengths
wide angle lens, normal lens, telephoto lens
if an Arri light is 650 watts, how many amps does that convert to?
+/- 6.5 amps
lens focal length - telephoto
- compresses space (makes things look closer than they are) - SHALLOWER depth of field.
lens focal length - wide angle
- expands space (makes things appear farther away) - GREATER depth of field
lens focal length - normal
- field of view/perspective similar to what the eye sees at the given distance from the subject
how does aperture affect depth of field?
- the smaller the aperture, the greater the depth of field. - the larger the aperture, the shallower the depth of field
what three factors affect exposure?
ISO, shutter speed, aperture
what does ISO stand for?
International Organization of Standardization
how is color temperature measured?
Kelvin scale
fresnel lights
a focusable lighting fixture with a fresnel lens, a reflector, and a track ex. Arri kit
what are the three basic shot sizes?
long shot, medium shot, close-up
what does putting the camera at a low-angle do?
makes subject seem scary or intimidating, big or powerful because they sit above the audience
what is color temperature?
measurement of warmth of light
what does it mean to "pull focus"?
moving focus from one thing to another using depth of field
