Question 1

A simple device that takes in a certain amount of light and emits a current in proportion to the amount of light falling on it is called a(n):&#10;A) Observable chamber&#10;B) Photoelectric cell&#10;C) Photon-electric cabal&#10;D) Bayer cell

Accepted Answer

A photoelectric cell, also known as a photocell, is a device that converts light energy into electrical energy. When light falls on the photocell, it emits electrons that flow as a current. The current produced by the photocell is proportional to the intensity of the light. Hence, a photoelectric cell is used to measure the intensity of light or to control the operation of a circuit based on the intensity of light. The other choices are not commonly used names for a photoelectric cell.

Question 2

Light values can be measured as either incident light or which of the following?&#10;A) Indigo light&#10;B) Reflected light&#10;C) Refracted light&#10;D) Exposure light

Accepted Answer

Light values can be measured as either incident light or reflected light. Incident light refers to the light that falls on the subject, while reflected light refers to the light that is bounced off the subject and measured by a light meter or camera metering system. Indigo light, refracted light, and exposure light are not commonly used terms in light measurement.

Question 3

If a photographer wants to meter only a small area of a scene, he or she would use which of the following?&#10;A) Spot meter&#10;B) Commercial meter&#10;C) Advertent meter&#10;D) Pinpoint meter

Accepted Answer

A spot meter allows the photographer to meter a small area of the scene, typically around 1-5% of the viewfinder area. The other options (commercial meter, advertent meter, pinpoint meter) are not commonly used or recognized photography terms.

Question 4

There have been numerous systems to mark the opening of the diaphragm, but most cameras now currently use this system:&#10;A) &#34;f&#34; system&#10;B) Convex system&#10;C) &#34;b&#34; system&#10;D) Spot method

Accepted Answer

The "f" system, also known as the f-number or f-stop, is the most commonly used method for marking the opening of the diaphragm in cameras. It represents the ratio of the focal length to the diameter of the aperture and is used for both manual and automatic exposure settings. This system is widely recognized and consistent across different brands and models of cameras.

Question 5

A colorless liquid that produces a light-emitting reaction when it comes in contact with blood is called:&#10;A) Viagra&#10;B) Luminol&#10;C) Cymbalta&#10;D) Vicoprofen

Accepted Answer

Luminol is a chemical substance that is used by forensic investigators to detect trace amounts of blood at crime scenes. When it comes into contact with blood, it produces a light-emitting reaction known as chemiluminescence, which can be detected using specialized equipment. Viagra, Cymbalta, and Vicoprofen are unrelated drugs and do not have any connection to this type of forensic analysis.

Question 6

Automatic cameras come in three basic types: Shutter priority, fully automatic and:&#10;A) Utterance&#10;B) Spot market&#10;C) Counter priority&#10;D) Aperture priority

Accepted Answer

The question states that there are three basic types of automatic cameras: shutter priority, fully automatic, and something else. The only other option given in the answer choices is aperture priority, which is a common feature in many automatic cameras. Therefore, the best choice is D, aperture priority.

Question 7

The _________________ tells the photographer how much more light is needed for correct exposure.&#10;A) Screen strainer&#10;B) Filter purifier&#10;C) Colander cuff&#10;D) Filter factor

Accepted Answer

The correct term for this is "filter factor", which describes the amount of additional light needed to compensate for the use of a filter on the camera lens.

Question 8

The primary complaint about cameras used in crime scenes today is that shutters are not adjustable on the camera, which prohibits extremely fast burst photography.

Accepted Answer

There is no evidence or widespread complaint about shutters not being adjustable on cameras used in crime scenes today.

Question 9

Intermediate shutter speeds cannot be obtained by setting the index between two marked speeds on the shutter housing.

Accepted Answer

Intermediate shutter speeds require adjustments beyond the marked speeds on the shutter housing, such as using a neutral density filter or adjusting the aperture.

Question 10

The principle of operation of most exposure meters is basically the same.

Accepted Answer

Most exposure meters operate by measuring the amount of light reflected from or incident upon the subject, and then calculating the appropriate settings for exposure. This principle is common to most exposure meters, regardless of their type or design.

Question 11

Due to recent developments in film processing, there is now an almost 100% success rate in making a good print from a badly exposed image.

Accepted Answer

The answer of Due to recent developments in film processing,...

Question 12

Exposure is defined as the amount of light that is allowed to reach the sensor by controlling the variables of aperture and shutter speed.

Accepted Answer

The answer of Exposure is defined as the amount of...
