Focal Length measured in

Answer 23

mm

The angle of View in relation to Focal Length?

Answer 29

Wide angle shows more of an angle of view

Question 30

How does Focal Length relate to Depth of Field?

Answer 30

The longer the lens, the less DOF you get at any aperture

Question 31

ISO

Answer 31

the numerical value given to the sensor or film's SENSITIVITY to light

Question 32

Which is considered a slower ISO? 125 or 400

Answer 32

125

Question 33

Lower # (ISO)

Slower ISO and needs more light

Question 34

Which ISO would need less light for an exposure? ISO 800 or 400?

Answer 34

ISO 800

Question 35

High # (ISO)

Answer 35

Faster, less light needed

Question 36

What is the benefit of using a faster ISO?

Answer 36

Will make images brighter, good for lower light, may not need to use a tripod

Question 37

Cons of faster ISOs

Answer 37

Grainy

Question 38

Benefits to using a slower ISO

Answer 38

it is less sensitive to light so you will have sharper images, allows for longer shutter speed

Question 39

Cons for slower ISOs

Answer 39

Need more light or a tripod

Question 40

3 Things that control Depth of Field?

Answer 40

Aperture Focal Length Length from Subject (Camera to Subject)

Question 41

The range of focus that exists in front of the sharpest plane of focus and behind the sharpest plane of focus is based on what ratio?

Answer 41

1/3 in front, 2/3 in back (or 1/3:2/3)

Question 42

Critical plane of focus?

Answer 42

what is your SUBJECT

Question 43

When you are close to your subject, how does that affect Depth of Field at any given aperture?

Answer 43

it will make your depth of field shallow; less DOF

Question 44

If you are shooting with a wide angle lens, how does that affect the Depth of Field?

Answer 44

you will have a longer DOF
