SCI-220 HUMAN ANATOMY FINAL EXAM ACTUAL
QUESTIONS AND ANSWERS GRADED A+
✔✔For program exposure the camera - ✔✔chooses the f/stop & shutter speed based
on what is detected with the light meter
✔✔In Aperture Priority Mode - ✔✔you set the f/stop & the camera sets the shutter
speed
✔✔Shutter Priority Mode - ✔✔you set the shutter speed & the camera sets the aperture
✔✔What is bracketing? - ✔✔Taking the same photo more than once, using different
settings for
different exposures
✔✔What is resolution? - ✔✔The ability of the camera system to distinguish alternating
line
pairs as they get thinner & closer together
✔✔What is Acutance? - ✔✔The camera's ability to render a sharp edge of the subject
as a
sharp edge in the photograph
✔✔What does it mean when the picture is sharp and in focus? - ✔✔light enters the
camera and converges at a sharp point on the
digital sensor
✔✔What are the circles of confusion? - ✔✔the light is a circle when it hits the digital
sensor, it will remain "confused" and out of focus
✔✔Light rays converging before or after
the digital sensor will always result in - ✔✔a blurry image
✔✔Wide-angle lenses can cause - ✔✔a barrel distortion
✔✔A telephoto lens can cause - ✔✔a pincushion distortion
✔✔How do you determine the DOF range with lens? - ✔✔•Choose focal distance
•Choose f/stop
•Check DoF scale to determine the
range
✔✔Three factors that affect DOF - ✔✔•f/stop choice
•Lens choice
, •Camera-to-subject distance
✔✔When do you want to minimize the DOF - ✔✔- daytime surveillance
-latent prints on glass
✔✔What is focal length? - ✔✔The distance (mm) between the optical center and the
sensor
when the camera is focused on infinity
✔✔What does the focal length tell us? - ✔✔•the angle of view—how much of the
scene will be captured
•the magnification—how large individual
elements will be.
✔✔ Photography is the creation of an image using - ✔✔light
✔✔In a midrange photo what is the primary subject? - ✔✔The evidence, fixed object, &
distance between them
✔✔What is composition? - ✔✔choosing what will be in focus in the photo
✔✔four composition issues - ✔✔1.Determine the primary subject and the composition
that
best captures it
2.Determine proper exposure
3.Select an optimal focusing technique
4.Determine the optimal lighting to use
✔✔What are the Cardinal Rules - ✔✔1. Fill the frame
2. Maximize depth of field
3. Keep the film plane parallel
✔✔A soft shadow allows - ✔✔you to see the detail within the shadow
✔✔What is Lens Flare? - ✔✔Sunlight directly enters the lens and creates images on the
lens' optical elements & aperture opening
✔✔What does a Macro Lens do - ✔✔•Take photographs with the lens closer to the
object than
with other lenses
•Makes small objects much larger
•Decreases the focal distance as compared to other lenses
✔✔PIXEL IMPORTANCE - ✔✔More pixels on the image
means better resolution when
