Understanding Depth of Field in Photography

What does DOF stand for?

• Degree of Focus

• Duration of Focus

• Depth of Field

• Direction of Focus

What happens to objects out of the DOF range?

• They move closer to the lens

• They begin to lose focus

• They change color

• They appear larger

What is a shallow depth of field?

• When the focus range is several yards to infinity

• When the focus range is very narrow

• When all objects are in focus

• When no objects are in focus

What does a small f/number indicate?

• Less light entering the lens

• A narrower aperture size

• A larger aperture size

• A deeper depth of field

What is the effect of a large f/number on depth of field?

• It has no effect on depth of field

• It creates a shallower depth of field

• It decreases the amount of light entering the lens

• It creates a deeper depth of field

What is the Sunny 16 Rule?

• A rule for night photography

• A rule for setting the shutter speed

• A rule for setting the aperture at f/16 in bright daylight

• A rule for setting the ISO

How does distance from the lens affect DOF?

• Closer objects have a deeper DOF

• Distance has no effect on DOF

• Farther objects have a shallower DOF

• Closer objects have a shallower DOF

What does changing the focal length do to DOF?

• Longer lenses provide greater DOF

• Shorter lenses provide shallower DOF

• Longer lenses provide shallower DOF

• It has no effect

What is the relationship between aperture size and shutter speed for exposure?

• Larger apertures always require slower shutter speeds

• Change one stop in aperture requires an opposite change in shutter speed

• Changing one does not require adjusting the other

• They are unrelated

What is the primary way to manipulate DOF without affecting composition?

• Changing the focal length

• Manipulating the aperture

• Moving closer to the subject

• Changing the ISO
