Photography Terminology

What is aperture in photography?

• The length of time the shutter is open

• The diameter of the entrance pupil of the lens

• The sensitivity of the camera sensor

• The amount of light per unit area reaching the camera sensor

What does a larger aperture size do?

• Increases the depth of field

• Decreases the depth of field

• Lets more light into the camera

• Lets less light into the camera

What is the focal ratio often abbreviated as?

• F-stop

• Shutter speed

• T-stop

• ISO number

What effect does a shallow depth of field have on an image?

• More of the image will be in focus

• Less of the image will be in focus, resulting in background blur

• Decreases the overall light entering the camera

• Increases the brightness of the image

What is bokeh?

• The amount of light a camera can physically gather

• The rendering quality of out-of-focus areas

• The brightness of an image

• A measurement of the size of the aperture

What does the shutter speed control?

• The sensitivity of the camera sensor

• The length of time the shutter is open, exposing the sensor to light

• The diameter of the lens's aperture

• The amount of light per unit area reaching the camera sensor

What is ISO an abbreviation for?

• Internal Sensor Optimization

• International Sensitivity Operation

• International Shutter Organization

• International Organization for Standardization

What does a high signal-to-noise ratio indicate?

• Information is barely recognizable from background noise

• The image is overexposed

• The image is underexposed

• Information clearly stands out against background noise

What is the purpose of shooting in RAW file format?

• To increase the brightness of the image

• To decrease file size

• To make it easier to edit in post-production

• To automatically adjust camera settings

What does the camera's meter do in auto mode?

• Determines the best ISO setting

• Adjusts the focal length of the lens

• Records the brightness of subjects to determine camera settings

• Controls the depth of field
