DIS Image Acquisition & Capture 2

Question 1

Which metering mode evaluates light from the entire scene and averages it, giving extra weight to the area near the focus point?

Accepted Answer

Matrix/evaluative metering

Answer

Matrix (Nikon) or evaluative (Canon) metering divides the scene into zones, analyzes each, and uses the focus point area as an additional factor.

Question 2

A photographer shoots indoors under fluorescent lighting without adjusting white balance. The images will most likely have a dominant color cast of:

Accepted Answer

Green-yellow

Answer

Standard fluorescent tubes emit a green-yellow spike in their spectrum, producing a green-yellow cast when the camera is set to Daylight WB.

Question 3

In photography, 'exposure latitude' refers to:

Accepted Answer

The range of exposures within which a sensor or film can capture acceptable detail

Answer

Exposure latitude describes how far over or under a 'correct' exposure a medium can be pushed while still rendering usable detail.

Question 4

What does the term 'bokeh' specifically refer to in digital imaging?

Accepted Answer

The aesthetic quality of the out-of-focus blur in an image

Answer

Bokeh (from Japanese 'boke') describes the visual quality—smooth, creamy, or busy—of the background blur created by shallow depth of field.

Question 5

When capturing an image of a fast-moving subject, which combination best freezes motion?

Accepted Answer

Fast shutter speed, wide aperture, higher ISO

Answer

A fast shutter speed freezes motion; opening the aperture and raising ISO compensates for the reduced exposure time.
