Cine 380

Question 1

How do you change quantity of light?

Answer 1

Scrims, distance from subject, dimmers, more light

Question 2

How do you change quality of light?

Answer 2

Haze/fog machines, silks/diffusion/muslin, reflection/bounce

Question 3

Inverse Square Law

Answer 3

The further away you are from the light source, the more spread out the light becomes

Question 4

Frame Rate

Answer 4

Frequency at which an image is captured for video

Question 5

Shutter Angle

Answer 5

180 degree rotation around the sensor, The larger the shutter angle, the lower the shutter speed
Small shutter angle, high shutter speed

Question 6

Contrast

Answer 6

The variation of shades of gray

Question 7

Dynamic Range

Answer 7

Stops: 1, 1.4, 2, 2.8, 4.0, 5.6, 8, 11, 16, 22

High DR: more details in overexposed/underexposed area

Question 8

Tungsten to Daylight filter

Answer 8

85 (2/3 stop)

Question 9

Daylight to Tungsten

Answer 9

80a (2/3 stop)

Question 10

ND Filters (numbers?)

Answer 10

ND 3, 6, 9

Question 11

Minimum Close Close Focus

Answer 11

Minimum of distance an object can be from the front of the lens that an object can be in focus

Question 12

Hyperfocal Length

Answer 12

Closest point of focus where depth of field extends to infinity

Question 13

Focal length

Answer 13

Distance in mm from nodal point in lens to film plane

Question 14

Focus Distance

Answer 14

Distance in feet or meters that focal ring is set to

Question 15

Distance to subject

Answer 15

Distance in feet or meters from film plane to subject

Question 16

Depth of field

Answer 16

Range of image that is in focus

Question 17

Prime lens

Answer 17

Fixed focal length

Question 18

Zoom lens

Answer 18

Variable focal length

Question 19

Telephoto lens

Answer 19

Long lens

Question 20

Lens Speed

Answer 20

A fast lens’ aperture can open wide and a slow lens lets in less light

Question 21

Wide angle

Answer 21

9-20mm for 16mm
Inclusive/larger canvas
More light to camera - because the focal length is shorter, it lets in more light
Separates foreground from BG (perceived distance)
Potential for deep focus

Question 22

Telephoto

Answer 22

50-120mm or more for 16mm
Exclusive/smaller canvas
Less light to camera
Collapses foreground and BG (flatter, less depth)
Potential for selective focus (due to shallower depth of field)

Question 23

Normal Lens

Answer 23

Sees approximately same magnification as the unaided eye
Keeps FG & BG relationship ‘normal’
Does not distort subject

Question 24

Depth of Field is determined by

Answer 24

Aperture
Distance to Subject
Focal Length

Question 25

2/3 Rule

Answer 25

In relation to a subject, 1/3 of image in front of subject and 2/3 behind is in focus

Question 26

Low key / high key

Answer 26

Low key is more contrast, high key is more even light

Question 27

Shot reverse shots should have:

Answer 27

Similar focal length DOF Framing Angle

Question 28

Pedestal

Answer 28

vertical movement up and down

Question 29

Blue Gel / Orange gel

Answer 29

CTB / CTO

Question 30

Controllable Qualities of Light

Answer 30

Direction - where light and shadows fall like sundials Shape / texture - using shadows as part of the composition to create shapes (smoke helps) Color Intensity - proximity, soft light scatters direction of light wave and hard light is direct
