Q

Focus

A

To adjust the optics of a lens to produce the correct level of sharpness in an image when it is projected by the lens onto a camera’s focal plane.

20
Q

A

One individual photo; frame is most commonly used to describe how many frame-per-second are shot when using a Continuous Drive mode.

21
Q

Frames-Per-Second (fps)

A

The number of photos that can be shot by a camera over the course of a second when using a Continuous Drive mode.

22
Q

F-stop

A

Name used to describe a LENS APERTURE VALUE.

23
Q

Fully Automatic

A

Shooting mode in which the majority of shooting functions are controlled entirely by the camera rather than the photographer.

24
Q

27
Q

Histogram

A

Graph showing the brightness range of tones in an image.

28
Q

Horizontal

40
Q

Low contrast

A

A scene or photo where there is a narrow tonal difference between the darkest and brightest areas.
