They distract the viewer
The opening in the lens that limits the amount of light passing through.
What is aperture?
What is the unit of measure for aperture?
F-stop
What is the relationship between opening size, f-stop, and depth of field?
Smaller f-stop = larger opening = shallower DoF
Variable range, from foreground to background, of what appears to be in sharp focus.
What is depth of field?
What effect does macro have on depth of field?
Drastically reduces DoF
Amount of time shutter stays open measured in fractions of a second.
What is shutter speed?
What is the relationship between shutter speed and amount of light allowed in?
Faster shutter speed = less light
Faster shutter speeds allow you to…
Freeze movement
Slower shutter speeds allow you to capture…
Blur
What is the tripod rule for shutter speed?
Any shutter speed slower than 1/60 requires a camera to be put on a tripod
What does ISO stand for?
International Organization for Standardization
What does ISO control in terms of shutter and aperture?
How the sensor responds to light it receives from shutter and aperture
What does a high ISO mean?
Brighter picture = more noise
Brighter pictures with greater amounts of noise show that the sensor is { } sensitive to light.
More
As a rule of thumb for ISO, doubled number equals…
Doubled brightness
For class, what ISO range should you strive for?
400 or below
This feature is how a camera determines the correct shutter speed and aperture.
What is metering?
Bracketing refers to…
Exposure
Underexposed photos have { } values while overexposed photos have positive values.
Negative
Does the camera’s flash typically reach far enough on its own?
No
What mode should the external flash be used in?
Through-the-lens (TTL)
The external flash’s auto mode that determines how much light to burst.
What is TTL mode?
What is the purpose of fill flash?
Fill shaded areas
For what 2 circumstances will a tripod be needed?

2) Photographing impression evidence
