Photo Quiz November Light

Front 1

4 basic laws of light

Back 1

travels in straight lines in all directions at once
can be reflected or deflected
can be absorbed
can be refracted or bent

Front 2

light travels in _____ lines in all directions at once

Back 2

straight

Front 3

what surface causes spectacular reflections (hot spots) and what type gives diffused reflections?

ex of surface

Back 3

specular from polished surface, diffused from matte surface

Front 4

ex of a surface that will cause specular reflections and one example of a surface that gives diffused reflections

Back 4

specular from polished surface - chrome, glass, marble, lacquered wood, high gloss paint

diffused from matte surface - fabric, concrete, bare wood, flat paint

Front 5

explain - "the angle of reflection equals the angle of incidence"

Back 5

when light hits a surface, it will reflect from that surface at the same angle that it hit

Front 6

what does it mean that absorption can be selective?

Back 6

when some wavelengths are absorbed but not others; red apple absorbs the white light's short and medium wavelengths - blue and green - but reflects most of the long wavelengths - red

Front 7

refraction

Back 7

the bending of light rays as they pass through one transparent medium to another

Front 8

what is the cause of the bend in the light's travel path?

cause of the cause?

Back 8

the light slowing down

the density of the transparent medium

Front 9

ambient light

Back 9

light that exists in a scene

Front 10

is all "mad-made" light "artificial light"?

Back 10

no man made lighting that exists in a scene is ambient when it comes to photography

Front 11

2 things that influence the quality of light

Back 11

intensity, source size

Front 12

how to determine whether light source is small or large

Back 12

source size is determined in relation to the subject

Front 13

will a source that is physically large automatically be large?

Back 13

no

Front 14

difference between small and large source lighting

ex

Back 14

small is small to subject, large is large to subject

Front 15

8 typical lighting classifications

Back 15

front, quarter, side, cross, back, overhead, low, diffused

Front 16

angle for quarter lighting

Back 16

45

Front 17

classification flattering for portraits

Back 17

quarter light

Front 18

classification used for commercial photography

Back 18

cross light

Front 19

dramatic effect classification

Back 19

low light

Front 20

characteristics of classification: soften features, incorrectly flat image

Back 20

diffused light

Front 21

difference between direct and indirect light

Back 21

direct travels directly from source to subject, indirect is not aimed at subject and is affected by diffusion/filtration/reflection

Front 22

working with flash, remember ____ about color

2 options for flash

Back 22

both flash and scene have color

alter mood with new color palette or blend flash with existing light

Front 23

what dilemma do you face with flash

Back 23

alter mood with color palette or blend flash with existing light

Front 24

best light during when

Back 24

early morning/ late afternoon

Front 25

natural light easiest to meter in

Back 25

front light

Front 26

natural light that is safest light

Back 26

overcast front light

Front 27

eleven tips for shooting in direct sunlight

Back 27

move into shade
make own shade
shoot into sun w/ fill flash
shoot into sun w/ reflector
change perspective
use lens hood
filters
white balance settings
metering
pick time of day to shoot
shoot silhouettes

Front 28

t/f flash is only used to supplement existing light and never as a primary light source

Back 28

false

Front 29

dr harold edgerton invented ____

Back 29

electronic flash

Front 30

inventor of electronic flash, one advantage

Back 30

dr harold edgerton, stops action

Front 31

the fastest shutter speed usable with flash

typical speed

Back 31

flash sync speed

1/200, 1/250

Front 32

what happens when shutter speed is faster than the flash sync speed

Back 32

the sensor is not fully exposed so there is a "flash-less" area of pic

Front 33

difference between front curtain sync and rear curtain sync

Back 33

front - flash at beginning
rear - flash at end

Front 34

t/f whether you choose front curtain sync for your flash or rear curtain sync only matters in longer exposures

Back 34

true

Front 35

what does ev compensation for flash do?

Back 35

reduce or increase the power output of the flash by up to 3 stops

Front 36

Back 36

direct flash

Front 37

drawbacks of which flash: flat light, washed out, hard shadows

Back 37

direct flash

Front 38

causes red eye

Back 38

direct flash

Front 39

benefit of using off camera flash

Back 39

off camera allows the flash to provide more modeling

Front 40

bounce flash

Back 40

aimed at a reflecting surface and the light is bounced off of that subject

Front 41

benefit of bounce flash

Back 41

good modeling with no harsh shadows

Front 42

drawback of bounce flash

Back 42

uses more power to bounce off ceiling, light falls from top to bottom, picks up color of reflecting surface

Front 43

does bounce flash require more power?

Back 43

yes

Front 44

are ceiling and walls only option for bounce

Back 44

no

Front 45

five benefits of fill flash

Back 45

allows you to illuminate areas in a scene that would be lost due to high contrast
allows you to expose properly and bring detail to subject
tones down harsh shadows
adds catch light in eyes
details in nature and macro
