SCI 220 Exam 1 Questions with Correct Answers Latest Update 2025/2026
Photography is the creation of an image using - Answers light
In a midrange photo what is the primary subject? - Answers The evidence, fixed object, &
distance between them
What is composition? - Answers choosing what will be in focus in the photo
four composition issues - Answers 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 - Answers 1. Fill the frame
2. Maximize depth of field
3. Keep the film plane parallel
A soft shadow allows - Answers you to see the detail within the shadow
What is Lens Flare? - Answers Sunlight directly enters the lens and creates images on the
lens' optical elements & aperture opening
What does a Macro Lens do - Answers •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 - Answers More pixels on the image
means better resolution when
enlarged
What id depth of field? - Answers The variable range of what appears in focus
Techniques to better depth of field - Answers Reciprocal exposure, hyperfocal focus, zone focus,
prefocus the camera
, Reciprocal exposure - Answers Use the one uses the smallest aperture (lens opening)
Hyperfocal focus - Answers •When the background is infinity
•Uses depth of field scale with the camera's distance scale
Zone focus - Answers •When infinity is not the background
•Focus by "rule of thirds" if the lens doesn't have a depth of field
scale
Prefocus the camera - Answers •Done with macro lenses
•Put the camera at its closest focusing position by rotating the
lens' focus ring to the shortest distance
•Set up camera at a distance where the object is in focus
What does keep the film plane parallel mean? - Answers •Keep the back of the camera parallel
to the subject
•Keep the length of the lens perpendicular to the subject
•Keep the front lens parallel to the subject
•Keep the digital sensor parallel to the subject
What do overall photographs show? - Answers Shows a larger view of an area, relationships

What do midrange photographs show? - Answers Shows a smaller view of an area, relationships
