Final Exam

Question 1

SLR

Answer 1

Single Lens Reflex, allows photography to see images as lens see it, interchangeable lenses

Question 2

Body

Answer 2

light tight box, houses working parts of camera

Question 3

Shutter

Answer 3

controls length of exposure, usually in fraction of a second, designated by shutter speed

Question 4

Diaphragm

Answer 4

controls intensity of exposure through adjustment of aperture size, designed by f/stop

Question 5

Lens

Answer 5

gathers and focuses light on film or sensors, designated by focal length

Question 6

ISO

Answer 6

sensitivity and grain or noise characteristics: 100 (least sensitive, requires more light for proper exposure, very little noise), 200, 400, 800, 1600, 3200 (most sensitive, requires less light for proper exposure, generates more noise)

Question 7

Shutter Speed

Answer 7

1/1 (Slow), 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/ 250, 1/500, 1/1000 (Fast)
Each one stop change in shutter speed results in 2x or 1/2 as much light reaching the sensor depending on direction of change

Question 8

F/ Stops

Answer 8

f2.8 (large aperture), f4, f5.6, f8, f11, f16, f22 (small aperture)
Each one stop change in f/ stop results in 2x or 1/2 as much light reaching the sensor depending on direction of change

Question 9

Depth of Field

Answer 9

the range of sharp focus in a photograph
f/ stop- depth of field decreases as f/# decreases
subject distance- depth of field decreases as you get closer to your subject
focal length of lens- depth of field decreases as focal length increases

Question 10

Focal Lengh

Answer 10

physical measurement of lens from front element to camera censor measured in millimeters ex. 24mm, 50mm, 200mm determines angle of view

Question 11

Wide Angle Lens

Answer 11

35mm or shorter
optically exaggerates distance between camera and subject
creates a greater depth of field
good for landscapes and shooting in tight spaces

Question 12

Normal Lens

Answer 12

50mm
Same field of view as human eye
no magnification

Question 13

Telephoto Lens

Answer 13

70mm or longer
optically magnifies subject, compressing distance between subject and camera
creates shallow depth of field
good for shooting subjects at a safe distance

Question 14

Zoom Lens

Answer 14

Variable Focal Length
adjustable focal length
many lens in one
ex. 18-55 mm, 70- 200mm

Question 15

Composition

Answer 15

the pleasing and artistic arrangement of subjects in a photograph

Question 16

Rule of Thirds

Answer 16

technique used to move the center of interest out of the middle of the frame by dividing the frame into thirds horizontally and vertically, place center of interest at any of the intersections to bring a more dynamic look

Question 17

Diffused Light

Answer 17

lighting without defined direction, produces even low contrast illumination with no distant shadows

Question 18

Direct Light

Answer 18

lighting with defined direction, producing high contrast illumination with distant shadows

Question 19

Front light

Answer 19

light coming from the direction of the camera, flat lighting

Question 20

Side Light

Answer 20

light rakes across the subject emphasizing texture and shadow

Question 21

Back Light

Answer 21

light comes from behind the subject; toward the camera creates highlights and silhouettes

Question 22

Pixels

Answer 22

picture elements

Question 23

Resolution

Answer 23

of pixels recorded by the sensor

Question 24

white balance

Answer 24

how cameras accurately record color temperature

Question 25

histogram

Answer 25

graphical display of the distribution of pixels in an image

Question 26

levels

Answer 26

how you alter the distribution of pixels
