SCI-220 HUMAN ANATOMY UPDATED EXAM SCRIPT
QUESTIONS AND ANSWERS GRADED A+
✔✔What do midrange photographs show? - ✔✔Shows a smaller view of an area,
relationships between a few
items
✔✔What do close-up photographs show? - ✔✔Shows one object in detail
✔✔What is exposure? - ✔✔How much light is in the picture
✔✔Underexposed means - ✔✔darker
✔✔Overexposed means - ✔✔lighter
✔✔What are "Stops"? - ✔✔used to express differences in exposure.
✔✔Changing stops either ___________ or__________ the overall lighting from the
original picture - ✔✔halves, doubles
✔✔Variables that directly affect exposure - ✔✔-shutter speed
-aperture
-ISO
-lighting within the scene
✔✔What is the shutter - ✔✔Located inside the camera body in Single Lens Reflex
(SLR)
cameras just in front of the digital sensor (light focuses here
✔✔B" (bulb) is used when shutter speeds are - ✔✔longer than those on the
camera are needed
✔✔Aperture - ✔✔size of the circular opening
✔✔A higher aperture (f/22) means that - ✔✔the opening is smaller and a larger depth of
field
✔✔A lower aperture (f/2.8) means that - ✔✔the opening is larger and has a smaller
depth of field
✔✔A higher ISO is - ✔✔more sensitive to light
✔✔A lower ISO means - ✔✔more light is needed for good exposure
, ✔✔If the ISO is faster this can result in - ✔✔graininess in the photo
✔✔When the natural light is bright you would use a - ✔✔slower ISO
✔✔When he light is dim you would use a - ✔✔faster ISO
✔✔When do you use an ISO of 100 - ✔✔Outside on a sunny day and when taking
close-up photos
✔✔When converting ISO to shutter speed, the shutter speed needs to be - ✔✔equal to
more more than the ISO
✔✔Convert an ISO of 100 to shutter speed - ✔✔1/125
✔✔Convert an ISO of 200 to shutter speed - ✔✔1/250
✔✔Convert an ISO of 400 to shutter speed - ✔✔1/500
✔✔Ambient light - ✔✔what is already present at the scene
✔✔What is white balance? - ✔✔The process of removing unrealistic colors
✔✔What three types of movement can be controlled by the shutter speed - ✔✔-
photographer body movement
-subject motion
-camera movement
✔✔When using reciprocal exposures, if you increase one variable 1 stop, - ✔✔decrease
the other by 1 stop
✔✔what is the reciprocal exposure if a shutter speed of 1/125th with an f/stop of f/4
when the shutter speed is changed to 1/60? - ✔✔f/5.6
✔✔what is the reciprocal exposure if a shutter speed of 1/500th with an f/stop of f/2
when the f/stop is changed to f/4 - ✔✔f/125
✔✔A "normal" scence has a _____ of the light is reflected back - ✔✔18%
✔✔For manual exposure you must - ✔✔manually set the f/stop and shutter speed for
each photo
✔✔For program exposure the camera - ✔✔chooses the f/stop & shutter speed based
on what is detected with the light meter
