Photographic professional examination question bank (2)

1. What are the main factors that affect the depth of field?

Answer: 1. Aperture size: The larger the aperture, the smaller the depth of field when the focal length of the lens is constant and the object distance is constant; The smaller the aperture, the greater the depth of field;

Second, the length of focal length: under the condition of constant aperture and constant object distance, the shorter the focal length of the lens, the greater the depth of field; The longer the focal length, the smaller the depth of field;

Third, the object distance: in the case of constant aperture and focal length, the farther the subject is from the camera, the greater the depth of field; The closer to the camera, the smaller the depth of field.

2. Illustrate the strength of reflection ability and its relationship with brightness with examples.

A: The reflection and absorption of a scene are inversely proportional. This characteristic is closely related to the structure and color of its surface. The stronger the reflection ability, the greater the brightness; The weaker the reflection ability, the smaller the brightness. Combine the above knowledge points to discuss.

3. Give an example to explain why low-light photography should be followed. More is better than less. The principle of?

A: Whether it's black-and-white film or color negative, the tolerance of overexposure is greater than underexposure. Film's perception of light is different from that of human eyes. The human eye has only a simple reflection function. Overexposure can not only show the outline of the scene, but also show the shadow level of the scene to a certain extent, and color film may also reproduce the color of the scene. If it is not enough, nothing is possible.

4. What is the composition and function of polarizer?

A: Polarizer is a kind of sandwich filter, which consists of two pieces of glass bonded together and wrapped in a vinyl film with tiny crystals with the same orientation.

First, reduce the brightness of the sky. A lot of light projected from the sky is polarized light, which can be stopped by a polarizer. When the shooting lens forms a 90-degree angle with the direction of the sun, the reduction degree is the greatest;

Second, control the reflection of non-metallic objects. Because the reflection from the metal surface is not polarized light. The limitation of shooting with a polarizer requires that the incident angle of the beam should be between 30 degrees and 49 degrees, and shooting should be taken from the position of reflection angle. It is also useless to use a polarizer to reflect the front camera glass;

Third, it can replace the medium gray color filter.

Fourth, enhance the saturation of color. Avoiding glare caused by reflection of smooth objects can increase color saturation.

5. How can portrait photography eliminate the reflection on glasses?

A: First, change the shooting location or character direction outdoors; Second, the indoor main light is higher. The auxiliary light should not be placed on the front, and the light should be soft and slightly dark. If the front must be used up, you can turn your head slightly left and right, or adjust the shooting angle slightly. Lift the plane. Use reflected light as the main light source. Avoid bright reflectors as much as possible.

6. Because of the close combination of digital camera and computer, it has advantages over traditional camera. What are these advantages? What are the advantages of having examples?

A: First, the imaging speed is fast and it has the function of instant shooting;

Combine the above knowledge points to discuss.

2 1. What is the main reason for underexposure?

A: First, the brightness of the light source is too low to produce moderate exposure on the photoreceptor;

Second, the exposure combination does not match the illumination, and the aperture is too small or the shutter speed is too fast, resulting in the light passing through the lens being lower than the exposure required by the photoreceptor;

Third, the sensitivity (ISO) index is too low.

22. What is the main reason for overexposure?

A: First, the illumination of the light source is extremely high, and the metering is not accurate;

Second, the setting of the aperture and shutter is inconsistent with the illumination of the light source, and the aperture is too large or the shutter speed is too low, resulting in too much light entering the lens, which exceeds the bearing capacity of the photoreceptor;

Third, the sensitivity (ISO) index is too high.
