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.
