Digital photography multiple-choice questions and answers, please ask relevant experts for answers. It doesn’t have to be all correct. . . The above is the question, and the following corresponds to ABCD in order.

The answer is in dark italics

1. (5 points) The following (?) are not lamps commonly used in studios.

Ordinary photographic incandescent lamps, iodine tungsten lamps

Studio flash lamps, small electronic flash lamps

Mercury lamps

Quartz lamps

2. (5 points) The keys to handling high-key photos include ( )

It must be shot with soft light (scattered light), and the exposure must be increased;

Must use Use hard light to shoot portraits and natural scenery, and greatly increase the exposure;

You must use cold light to shoot, and reduce the exposure;

You must use condensed light to shoot, and reduce the exposure.

3. (5 points) Types of light positions of photography light sources: forward lighting, ( ), and backlighting.

Lighting

Sunlight lighting

Side lighting

Artificial lighting

4. (5 Points) Factors affecting changes in natural illumination: season, time, ( ).

Focal length, film

Depth of field, location

Aperture, time

Climate, location

2. More Topic selection (***4 questions)

1. (5 points) Which of the following statements is correct ()

If the light ratio is very large and the photo is taken against the light, it must be a silhouette Photos;

Photos with low contrast are called hard-key photos;

Photos with high contrast are called soft-key photos;

High light ratio means high contrast. .

2. (5 points) Which of the following statements is correct? ()

Backlight shooting can produce vivid contour lines, with a strong sense of three-dimensionality and space;

< p>Top light is suitable for portrait shooting.

When shooting with side light, the shadow tone is bright, the three-dimensional effect is weak, and the shadow area is small;

When shooting with side light, the three-dimensional effect is strong and the shadow area is large.

3. (5 points) When photographing waterfalls with a digital camera, which of the following statements is correct ()?

Photos with high contrast are hard-keyed photos and have a simple and bright effect;

Photos with low contrast are soft-keyed photos and have a soft and delicate effect;

If the light ratio is very large and it is backlit, it will be a silhouette photo;

It is not necessary to use scattered light to take high-key photos

4. (5 Points) When describing light, the following statement is correct ( )

Fill light is mainly used to soften shadows and reduce light ratio;

Backlighting can easily create the silhouette effect of the subject. ;

Front lighting can make the color of the subject bright;

Not all of the above are correct.

3. True or False Questions (***2 questions)

1. (5 points) Light ratio is one of the important parameters in photography, which refers to the brightness of the light-receiving surface of the object The ratio to the brightness of the shadow surface is often expressed in the ratio of "brightness of the light-receiving surface/brightness of the shadow surface".

True

False

2. (5 points) Photographic lighting refers to the use of artificial light.

True

Wrong

1. Multiple choice questions ( ***Question 2)

1. (5 points) What is correct about depth of field and depth of focus (? )

The greater the depth of field, the greater the depth of focus.

The depth of field is small, and the depth of focus is also small.

They are all used to illustrate the depth range of the object side and image side where the lens can form a fairly clear image;

All of the above are correct.

2. (5 points) The relationship between the aperture coefficient and the shutter speed is: ().

The image brightness of f/1.4 is the same as that of f/2;

The larger the aperture coefficient, the faster the shutter speed; the smaller the aperture coefficient, the slower the shutter speed;

< p>It doesn't matter;

A large aperture coefficient means a slow shutter speed; a small aperture coefficient means a fast shutter speed.

2. Multiple-choice questions (***4 questions) 1. (5 points) Which of the following statements is correct ()

When taking landscape photos, use a smaller aperture coefficient ;

Use a small aperture coefficient to blur the background;

When taking landscape photos, use a larger aperture coefficient;

Use a larger aperture coefficient; A high shutter speed can produce a "frozen" effect on moving objects.

2. (5 points) Regarding exposure, the following statement is correct ( )

When the exposure is constant, the exposure time is proportional to the illumination;

When the exposure time is constant, the exposure amount is proportional to the illumination;

When the exposure time and illumination both increase, the exposure amount also increases.

When the illumination is constant, the exposure amount is inversely proportional to the exposure time;

3. (5 points) When describing the depth of field, which of the following statements is correct ( )

< p>The brighter the subject, the longer the focal length;

Focal length and aperture coefficient are related, and the two are directly proportional;

Exposure time has nothing to do with focal length;

The shorter the exposure time, the longer the focal length.

4. (5 points) The best exposure mode for photographing moving objects in a digital camera is ( )

Complete manual mode

Shutter priority exposure mode

Aperture priority exposure mode

Program automatic exposure mode

3. True or false questions (***3 questions)

1. (5 points) Accurate exposure means that the photo has details from bright to dark parts.

True

Wrong

2. (5 points) The focal length and object distance remain unchanged. The larger the aperture, the shorter the depth of field. The smaller the aperture, the shorter the depth of field. deep.

True

False

3. (5 points) Focal length refers to the distance from the center point of the lens in the camera to the focal plane.

True

Wrong
