Quiz 3 & 4 CTVA 300 UPDATED ACTUAL Questions and
CORRECT Answers
foot candle A unit of illumination equivalent to 1 lumen per square foot.
exposure the quantity of light or other radiation reaching a photographic film, as
determined by shutter speed and lens aperture.
aperture an aperture is a hole or an opening through which light travels.
open aperture When the diameter of the aperture is bigger/open. It allows more light to come in
closed aperture When the diameter of the aperture is small. Allows less light to come in
T-stop amount of light transmitted through the opening in the lens
Underexposure Low light in a photo. Dark.
Overexposure Too much light enters the aperture of a camera lens, bleaching out the image.
Useful for fantasy and nightmare scenes.
How many foot candles of light are there in a typical between 50 and 70 foot candles of light falling on objects throughout the room,
CSUF classroom? in the sunlight at 3 pm on a clear day? perhaps 20 or 30 foot candles under a desk. in sunlight is about 8k to 10k
How does a reflective light meter work? an incident light Reflective:
meter? The cinematographer looks through the viewfinder on the right (that's an eyeball,
... trust me) and aims the meter at the object he or she wishes to measure.
Incident:
the cinematographer holds the meter at the subject or object he or she wishes to
measure, aiming the white bulb at the top of the meter toward the light source.
What three factors influence an exposure? the relation of light, the film stock, and the lens' aperture.
What are some differences between a slow and a fast Slow:
stock? lower ASAs or ISOs, are less sensitive to light, requiring therefore more
light than a fast stock in order to make a properly exposed image.
Fast:
higher ASAs or ISOs, are more sensitive to light. This means they require less light
in order to make a properly exposed image.
Describe the difference between T/16 and T/4. Between T/16 is 4 stops more open the T/4. T/2.8 is 1 stop more open than T/4 and T/5.6 is 2
T/2.8 and T/4. Between T/5.6 and T/11. Which one is more stops more open than T/11. The smaller the number the more open it is. The bigger
open? Which one lets in more light? How much more? the number the more closed it is. more open, more light/ Less open, less light.
What are the qualities of an underexposed image? an overexposed image is going to be birght and bleeched out while an
overexposed image? underexposed image is dark and hard to see in some spots.
, What causes the silhouette effect in the image on the top the cinematographer decided to expose the backround and not Mr. Lavant
of page 9 of this unit? resulting in him and the chair to be underexposed campared to amount of light
outside.
How do the filmmakers use exposure to structure the He tells his story in their darkened cabin late at night. Most of the room is severely
materials in scene from Hour of the Wolf linked above? underexposed. The husband's dream, in which a little demon boy attacks himis
more exposure-wise, with the shots before and after it. Subjects in that dream are
severely overexposed.
What are the effects of the change of aperture during the When the man is about to tell his wife the story it has more closed aperature.
shot linked above from Hélas pour moi on the image? When the story is being acted out it contains more open aperature.
focal length distance between the lens and the image sensor when the subject is in focus
Fixed Lens (prime lens) a fixed focal length photographic lens (as opposed to a zoom lens)
zoom lens a lens with a focal length that can be changed during a shot (zooms in or out)
rack going from one focal length to another (adjusting the size of the field-of-view)
dolly-counterzoom the zoom and the camera movement in the opposite direction
What are the differences in focal lengths among short, normal lens = 40-60mmshort/wide angle lens = below normallong/telephoto =
long, and normal focal length motion picture lenses? above normal
What is the effect of focal length on degree of With respect to magnification, the longer the focal length, the greater the size of
magnification of a subject? the subject matter
In what way do some extreme short focal length lenses The short focal length lens seems to "stretch" space along the z-axis. In sum, the
affect the quality of line of an image? wide lens exaggerates the relative differences in size between objects in the
foreground and objects in the background.
How do short focal length lenses render space? long expand space
focal length lenses? normal lenses? compress space
flat space
In what way do short focal length lenses affect perceived Because short lenses seem to expand the space between foreground and
speed of movement along the z-axis? What about normal background, any movement along the z-axis (movement from front to back,
focal length lenses? long focal length lenses? towards or away from the camera, or vice versa) is also exaggerated. The long
lens has compressed the space between foreground and background with the
result that it takes what seems a very long time for someone to cover what looks
like (but in fact isn't) a short distance.
What effects do short and long focal length lenses have wide-angle lens used to shoot him has exaggerated his features, making his nose
an actors' faces? seem unnaturally bigger than his mouth and bad 60s sideburns.The long lens
compresses the space between the actress' nose and her ears, flattening her
features.
