Photography Exam 1
One stop change up in aperture is --
1/2 the light
What fraction of the depth of field is in front (between the camera and the subject) of the focused subject?
1/3
What fraction is the depth of field is behind the focused subject?
2/3
Low/Slow shutter speeds --
Blur the subject
How does focus distance affect depth of field?
The closer the focus to the camera, the smaller the depth of field.
Shutter speed controls --
The depth of field
Which aperture will give the biggest opening (and therefore shallow depth of field)?
f1.4
Which aperture will give the most light?
f1.4
Which of the following apertures with give the least depth of field? - f22 - f11 - f8 - f2.8
f2.8
Which aperture will give the least amount of light?
f22
Which aperture will give the smallest opening (and therefore large depth of field)?
f22
Which of the following apertures with give the most depth of field? - f22 - f11 - f8 - f2.8
f22
The closer the camera is to the focused subject, the ___ the depth of field
shallower
A moving subject will be less blurred if it is moving _____ the camera.
towards or away
The smaller the aperture opening --
- The greater the depth of field - The least amount of light - The most focus
The lower the ASA/ISO --
- The less sensitive to light - The smoother the tones (or shades of grey) - The more potential color - The less noise
The higher the ASA/ISO --
- The more sensitive to light - The lesser the smoothness of tones - The less potential color - The more noise
The bigger the aperture opening --
-The shallower the depth of field - The most amount of light - The least focus
Which shutter speed will blur action best?
1
One stop change down in aperture is --
2x the light
Which shutter speed will stop action best?
4000
Which of the following ISO/ASAs will be the least sensitive to light? - ASA 100 - ASA 200 - ASA 400 - ASA 800
ASA 100
Which of the following ISO/ASAs will be the most sensitive to light? - ASA 100 - ASA 200 - ASA 400 - ASA 800
ASA 800
Which of the following ISO/ASAs will give the fastest shutter speed at the same fstop? - ASA 100 - ASA 200 - ASA 400 - ASA 800
ASA 800
Depth of field is controlled by what three things?
Aperture, focus distance, and focal length
What is the relationship between shutter speed and aperture?
Inverse - when one goes up, the other goes down
What is the effect of shutter speed on depth of field?
None
ASA/ISO measures --
Sensitivity to light
High/Fast shutter speeds --
Stop the subject in motion
How does aperture affect the depth of field?
The bigger the opening, the shallower the depth of field. The smaller the opening, the greater the depth of field.
Aperture controls --
The size of the opening of the lens, depth of field, and volume of light entering the camera
How does focal length affect depth of field?
The longer the focal length, the less depth of field. The angle of view is also changed.
