Question 1

As defined by its focal length, a lens may be a
A) wide angle lens.
B) normal lens.
C) telephoto lens.
D) all of the above.

Accepted Answer

All three options (wide angle, normal, telephoto) are defined by the focal length of a lens. Therefore, the correct answer is D.

Question 2

The amount of scene included in the frame of a shot is called the
A) landscape.
B) field of view.
C) the focal plane.
D) none of the above.

Accepted Answer

The amount of scene included in the frame of a shot is called the field of view.

Question 3

Exposure is controlled by
A) the length of the lens.
B) the amount of daylight available.
C) aperture, shutter speed, and sensitivity.
D) none of the above.

Accepted Answer

Exposure is controlled by the three factors of aperture, shutter speed, and sensitivity. The aperture controls the amount of light that enters the camera, the shutter speed controls the amount of time that the sensor is exposed to light, and the sensitivity (ISO) determines how quickly the sensor responds to light. None of the other options listed are accurate ways to control exposure.

Question 4

Aperture can be measured in
A) f-stops.
B) t-stops.
C) both a and b.
D) none of the above.

Accepted Answer

Aperture can be measured in both f-stops and t-stops, so both options are correct.

Question 5

Depth of field is controlled by
A) aperture, distance from the subject, and focal length.
B) aperture and shutter speed.
C) focal length and sensitivity.
D) none of the above.

Accepted Answer

Depth of field is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. It is controlled by several factors, including the aperture (larger apertures create shallower depth of field, while smaller apertures create greater depth of field), the distance from the subject (closer distances create shallower depth of field, while farther distances create greater depth of field), and focal length (longer focal lengths create shallower depth of field, while shorter focal lengths create greater depth of field). Shutter speed and sensitivity (ISO) do not directly affect depth of field.

Question 6

The most common type of camera for professional work is
A) the standard point-and-shoot.
B) the Kodak Brownie.
C) a medium-format camera.
D) a single-lens reflex camera.

Accepted Answer

Single-lens reflex (SLR) cameras are the most common type of camera for professional work because they allow for interchangeable lenses, manual control over settings, and a through-the-lens viewfinder that accurately shows the image that will be captured. Medium-format cameras are also commonly used for professional work, but are more specialized and expensive than SLRs. Point-and-shoot cameras and the Kodak Brownie are not commonly used for professional work due to their limited control and image quality.

Question 7

There are two types of film:
A) point-and-shoot and SLR.
B) negative and reversal.
C) ISO and ASA.
D) none of the above.

Accepted Answer

The two types of film are negative and reversal. Negative film creates a negative image that must be turned into a positive print, while reversal film creates a positive image directly on the film itself. This choice is the most accurate among the options given.

Question 8

The most common size of film for still photography is
A) 10 megapixels.
B) 45mm.
C) 35mm.
D) none of the above.

Accepted Answer

The most common size of film for still photography is 35mm. Megapixels refer to digital photography resolution and 45mm is a focal length of a lens.

Question 9

Printed photographs are made from
A) negative film.
B) reversal film.
C) overexposed film.
D) none of the above.

Accepted Answer

Printed photographs are typically made from negative film, which is developed and then used to create a positive image on paper. Reversal film is used to create slides, not printed photographs, and overexposed film would produce poor quality images.

Question 10

With digital prints, resolution is determined by
A) the size of your camera.
B) how much you spend on your lenses.
C) the size of the image and the dpi of the printer.
D) where the image will be used.

Accepted Answer

Resolution in digital prints is determined by the size of the image and the DPI (dots per inch) of the printer. The higher the DPI, the more detail and clarity the print will have. The size of the camera and the cost of lenses may affect the quality and sharpness of the original image, but it does not directly determine the resolution of the final print. Similarly, where the image will be used may affect the necessary resolution for optimal viewing, but it does not determine the resolution of the print itself.

Question 11

Digital images are often compressed, which means
A) the file size of the image has been mathematically reduced.
B) the light that enters the camera is shrunk by the limitations of the sensor.
C) the image has been cropped.
D) the image has been converted to gray scale for storage.

Accepted Answer

Digital images are often compressed to reduce the file size for storage and transmission purposes. This compression is achieved by using mathematical algorithms to reduce the amount of data needed to represent the image while still maintaining its visual quality.

Question 12

There are several ways to shoot extreme widescreen with film, including
A) filming with an anamorphic lens.
B) shooting with several cameras next to each other.
C) using standard film and letterboxing out the top half of the image.
D) all of the above.

Accepted Answer

Filming with an anamorphic lens is the best choice for shooting extreme widescreen with film as it allows for a wider field of view and preserves the image quality without letterboxing or multiple cameras. Shooting with several cameras next to each other can result in inconsistencies and difficulties during post-production, while letterboxing out the top half of the image will result in a loss of image quality and resolution.

Question 13

The phrase boosting the gain refers to
A) the opening of a camera's aperture.
B) amplifying the strength of an electronic signal after it is formed.
C) cherry-picking the best images during editing.
D) none of the above.

Accepted Answer

Boosting the gain refers to amplifying the strength of an electronic signal after it is formed. This is often done to increase the volume or clarity of audio signals or to enhance the brightness or detail of images. A camera's aperture opening and cherry-picking images during editing are unrelated to boosting the gain.

Question 14

Barrel distortion is when objects at the extreme edges of the frame curve toward the center of the frame.

Accepted Answer

Barrel distortion is a common lens distortion where straight lines near the edges of the frame curve outward, creating a barrel shape. This causes objects at the extreme edges of the frame to appear to curve toward the center of the frame.

Question 15

The characteristics of a telephoto lens tend to be the same as a wide-angle lens.

Accepted Answer

The characteristics of a telephoto lens are not the same as a wide-angle lens. Telephoto lenses have a narrower angle of view and tend to compress the scene, while wide-angle lenses have a wider angle of view and tend to exaggerate perspective.

Question 16

A fast shutter speed will appear to freeze action.

Accepted Answer

A faster shutter speed allows for less time for motion blur to be captured in the image, resulting in a frozen or sharp appearance of the subject in motion.

Question 17

A circle of confusion is the effect an unbalanced image has on the viewer.

Accepted Answer

A circle of confusion refers to the blur or lack of sharpness in an image caused by factors such as lens aperture and focus distance. It is not related to the viewer's perception or experience of the image.

Question 18

Negative film is used for creating slides.

Accepted Answer

Negative film is not used for creating slides. Positive film or transparency film is used for creating slides.

Question 19

The sensitivity of film is indicated by a numerical rating, such as an ISO rating.

Accepted Answer

Film sensitivity is indicated by a numerical rating, and this rating is commonly referred to as ISO.

Question 20

The number of pixels on a sensor has no bearing on image resolution.

Accepted Answer

The number of pixels on a sensor directly affects the potential image resolution, as more pixels allow for more detail and higher resolution images.
