• 1.

### Which f-stop give you the least depth of field in a photograph?

• A.

16

• B.

2.8

• C.

22

• D.

8

B. 2.8
Explanation
The f-stop value determines the size of the aperture opening in a camera lens. A lower f-stop value, such as 2.8, means a larger aperture opening, which allows more light to enter the camera. This larger aperture creates a shallower depth of field, meaning that only a small portion of the image will be in focus while the rest will be blurred. Therefore, an f-stop value of 2.8 gives you the least depth of field in a photograph.

### To freeze action in a photograph, which shutter speed would work best?

• A.

1/2

• B.

1/60

• C.

1/1000

• D.

1/45

C. 1/1000
Explanation
A shutter speed of 1/1000 would work best to freeze action in a photograph. A faster shutter speed allows for a shorter exposure time, capturing the subject in motion without any blurring. This is particularly useful when photographing fast-moving subjects such as sports or wildlife, where a slower shutter speed would result in motion blur.

### If you want to blur an image, do you use a slower or faster shutter speed? _________

• A.

Slower

• B.

Faster

A. Slower
Explanation
When you want to blur an image, you use a slower shutter speed. A slower shutter speed means that the shutter remains open for a longer period of time, allowing more light to enter the camera sensor. This longer exposure time allows for any movement in the scene to be captured as motion blur, resulting in a softer and more blurred image. Conversely, a faster shutter speed would freeze motion and result in a sharper image.

### Which f stop gives you the greatest depth of field?

• A.

22

• B.

16

• C.

11

• D.

2.8

A. 22
Explanation
A higher f-stop number, such as f/22, gives you a smaller aperture opening, which increases the depth of field. This means that more of the image, from the foreground to the background, will be in focus.

### Aperture, Shutter Speed, and ______________ play a major role in exposure.

ISO shutter speed
Explanation
Aperture, shutter speed, and ISO are all important factors in determining the exposure of a photograph. The aperture refers to the size of the opening in the lens that allows light to pass through. Shutter speed is the amount of time that the camera's shutter remains open, determining how long light is allowed to reach the camera's sensor. Film speed, or ISO, refers to the sensitivity of the film or digital sensor to light. Together, these three elements control the amount of light that enters the camera and ultimately affect the exposure of the image.

### What controls length of time light enters the camera?

• A.

Shutter

• B.

Aperture

• C.

ISO

A. Shutter
Explanation
The shutter controls the length of time that light enters the camera. It is a mechanism that opens and closes to allow light to reach the camera's image sensor. By adjusting the shutter speed, the photographer can control how long the shutter remains open, thus determining the amount of light that enters the camera. A faster shutter speed allows less light to enter, while a slower shutter speed allows more light to enter.

### If your metered exposure was 1/125 and f8, which would be an equivalent exposure?

• A.

1/500 and f16

• B.

1/60 and f16

• C.

1/60 and f11

• D.

1/500 and f4

C. 1/60 and f11
Explanation
The given question is asking for an equivalent exposure to a metered exposure of 1/125 at f8. An equivalent exposure means finding a combination of shutter speed and aperture that would result in the same amount of light reaching the camera sensor. In this case, the correct answer is 1/60 and f11. By decreasing the shutter speed from 1/125 to 1/60, we are allowing more light to reach the sensor. To compensate for this increase in light, we need to decrease the aperture from f8 to f11, which reduces the amount of light entering the lens. This combination of settings will result in the same exposure as the original metered exposure.

### What do we call a lens with a focal length longer than the standard?

• A.

Telephoto

• B.

Zoom

• C.

Wide Angle

• D.

Macro

A. Telephoto
Explanation
A lens with a focal length longer than the standard is called a telephoto lens. Telephoto lenses have a narrow field of view and are often used in photography to capture distant subjects. They allow the photographer to zoom in and get closer to the subject without physically moving closer. This makes them ideal for wildlife, sports, and portrait photography, where the subject is often far away.

• 9.

### Which ISO will generally produce more noise?

• A.

100

• B.

1600

B. 1600
Explanation
ISO measures the sensitivity of the camera's image sensor to light. A higher ISO value indicates a higher sensitivity to light, which can be useful in low-light conditions. However, increasing the ISO also increases the amount of noise in the image. Therefore, a higher ISO value, such as 1600, will generally produce more noise compared to a lower ISO value like 100.

### As a general rule of thumb, after what shutter speed do you need to use a tripod?

1/60
Explanation
A shutter speed of 1/60 or slower typically requires the use of a tripod. This is because at slower shutter speeds, any movement of the camera can result in motion blur in the image. Using a tripod helps to keep the camera steady and eliminates camera shake, ensuring sharp and clear images.

Rate this question:

• 11.

### What does the ISO value represent?

• A.

Film speed

• B.

Film/sensor's sensitivity to light

• C.

Both

C. Both
Explanation
The ISO value represents both the film speed and the film/sensor's sensitivity to light. Film speed refers to the film's ability to capture images in low light conditions, while the sensitivity to light refers to the sensor's ability to capture light and produce a well-exposed image. The ISO value determines how quickly the film or sensor responds to light, with higher ISO values indicating greater sensitivity and faster response.

### How much light will an f-stop of f/2.8 let through compared to an f-stop of 4?

• A.

Half as much

• B.

Twice as much

• C.

• D.

Four times as much

B. Twice as much
Explanation
An f-stop of f/2.8 will let through twice as much light compared to an f-stop of 4. The f-stop is a measurement of the aperture size, which determines how much light enters the camera. A lower f-stop number indicates a larger aperture, allowing more light to pass through. In this case, f/2.8 has a larger aperture than f/4, so it will allow twice as much light to enter the camera.

### Which shutter speed should you use to take a photo of moving water?

• A.

1/2

• B.

1/1000

A. 1/2
Explanation
A shutter speed of 1/2 would be the ideal choice for capturing a photo of moving water. This slower shutter speed allows the water to appear smooth and silky in the image, creating a sense of motion. A faster shutter speed like 1/1000 would freeze the water in place, resulting in a more static and less dynamic photograph.

### What is the purpose of a tripod?

• A.

To avoid camera shake at fast shutter speeds

• B.

To avoid camera shake at small apertures

• C.

To avoid camera shake at slow shutter speeds

• D.

To avoid camera shake at large apertures

C. To avoid camera shake at slow shutter speeds
Explanation
A tripod is used to avoid camera shake at slow shutter speeds. When using a slow shutter speed, any slight movement or shake of the camera can result in blurry or distorted images. By placing the camera on a tripod, it provides a stable and secure base, allowing the camera to remain perfectly still during the exposure. This helps to capture sharp and clear images, even in low light conditions or when using longer exposure times.
