Q

Two basic types of focusing screens are used on SLR cameras:

A

A. SPLIT-IMAGE SPOT. A circular spot in the center of the focusing screen breaks the image into two parts that do not match up. The lens is properly focused when the two images form a single image.

B. MICROPRISM. A small circle in the center of the focusing screen appears dark and the image within the spot is blurred until the lens is properly focused.

Q

Focusing zone cameras

A

Cameras with fixed focal distances.

Q

Why is a Through-The-Lens (TTL) metering system preferred over a hand held exposure meter?

A

It compensates for different lenses and filters as the light passes through them.

15
Q

Averaging Meter System

A

two or more sensors that measure the average amount of reflected light in the image

16
Q

Backlighted Subject

A

a silhouetted subject as result of a light source being placed behind the subject

17
Q

Bracketing

A

taking a picture several times with different aperture/shutter speed combinations to assure proper exposure

18
Q

Center-weighted Metering System

A

multiple sensors that averages the amount of reflected light, but place extra emphasis on the center of the scene

19
Q

Focusing Zone

A

lens settings based on fixed ranges that are in focus. This is only found on cheap cameras.

20
Q

Follow Pointer Lens

A

two needles used to indicate the metered exposure. One needle indicates the recommended exposure and the second needle indicates the current exposure settings.

21
Q

Framing

A

partially or completely surrounding the subject with objects in the foreground

22
Q

Incident Light Exposure System

A

an instrument that measures the light falling on the subject

23
Q

LED Display

A

LED lights or images used to replicate the Single Pointer and Follow Pointer Displays

24
Q

Meter Calibration

A

adjusting the light sensors to produce medium grey tones when 18% of the light is reflected off the subject.

25
Q

Metering

A

measuring the amount of light reaching the film

26
Q

Panning

A

following a moving subject with the camera while taking the picture to keep the subject in focus

27
Q

Red Eye

A

the result of the flash being too close to the eyes resulting in reflection of the blood vessels

28
Q

Reflected Light Exposure Meter

A

light exposure meter- a device that measures the light bouncing off a subject

29
Q

Single Needle Display

A

a single needle that moves between fixed points to indicate the metered exposure

30
Q

Spot Metering

A

a single sensor measuring the reflected light at the center of a scene. Extra care must be used to measure the subject.

31
Q

TTL Metering

A

(Through the Lens) built in light sensors that measure the light traveling through the lens of the camera.
