SCI 220 Exam 1 Questions and Correct Answers
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
enlarged
What id depth of field?
The variable range of what appears in focus
Techniques to better depth of field
Reciprocal exposure, hyperfocal focus, zone focus, prefocus the camera
Reciprocal exposure
Use the one uses the smallest aperture (lens opening)
Hyperfocal focus
•When the background is infinity
•Uses depth of field scale with the camera's distance scale
Zone focus
