A simple quiz to test the fundamentals of photography- understanding aperture and shutter speed.

• 1.

### When you change the aperture setting on your camera, what are you actually changing?

• A.

How large of an opening the curtain makes on the camera

• B.

How large of an opening the blades in the lens make

• C.

The focus of the lens

• D.

How fast light is recorded on your digitial or film sensor

B. How large of an opening the blades in the lens make
Explanation
When you change the aperture setting on your camera, you are actually changing the size of the opening that the blades in the lens make. The aperture controls the amount of light that enters the camera, and by adjusting the size of the opening, you can control the depth of field and the amount of light that reaches the sensor. A larger aperture (smaller f-number) creates a wider opening, allowing more light to enter, while a smaller aperture (larger f-number) creates a narrower opening, allowing less light to enter.

### When you shoot using the lowest number possible for your aperture, what is it called?

• A.

Shooting "slow"

• B.

Shooting "low"

• C.

Shooting "wide open"

• D.

Shooting "fast"

C. Shooting "wide open"
Explanation
When you shoot using the lowest number possible for your aperture, it is called shooting "wide open". The aperture refers to the opening in the lens that controls the amount of light entering the camera. By using the lowest aperture number, such as f/1.8 or f/2.8, the lens is opened up to its maximum capacity, allowing more light to enter the camera and resulting in a shallow depth of field. This technique is often used in low-light situations or to achieve a blurred background effect.

• B.

The total distance from near to far that you are capturing in your photo

• C.

How much of your photo from near to far is in sharp focus

• D.

How fast your shutter captures the sharpness of the image

C. How much of your pHoto from near to far is in sharp focus
Explanation
Depth of field refers to the range of distance in a photograph that appears to be in sharp focus. It determines how much of the photo, from the nearest point to the farthest point, is captured with clarity.

### What is another term for Aperture?

• A.

Shutter speed

• B.

F-stop

• C.

ISO

• D.

Focal length

B. F-stop
Explanation
F-stop is another term for Aperture. Aperture refers to the opening in the lens that controls the amount of light entering the camera. The f-stop is a numerical measurement used to represent the size of the aperture. A lower f-stop number indicates a larger aperture, allowing more light to enter the camera, while a higher f-stop number represents a smaller aperture, allowing less light to enter. Therefore, F-stop is the correct answer as it is a term commonly used in photography to describe the aperture setting.

### What 3 things determine the exposure of a photograph?

• A.

Aperture, shutter speed, ISO

• B.

Shutter speed, ISO, metering mode

• C.

Aperture, f-stops, timer mode

• D.

F-stop, aperture, depth of field

A. Aperture, shutter speed, ISO
Explanation
The exposure of a photograph is determined by three factors: aperture, shutter speed, and ISO. 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 is open, determining the duration of light exposure. ISO is the sensitivity of the camera's image sensor to light. These three factors work together to control the amount of light that reaches the camera's sensor, ultimately determining the exposure of the photograph.

### Compared to f/8, f/16 is:

• A.

A larger opening

• B.

A smaller opening

• C.

Farther away

• D.

Blurrier

B. A smaller opening
Explanation
The f-stop number represents the size of the aperture opening in a camera lens. A smaller f-stop number indicates a larger opening, allowing more light to enter the camera. Conversely, a larger f-stop number represents a smaller opening, allowing less light to enter. Therefore, f/16 is a smaller opening compared to f/8.

### You’re taking a picture of your golden retriever, Max jumping to catch a frisbee. Which of these shutter speeds would best freeze the action?

• A.

1/50th

• B.

1/100th

• C.

1/500th

• D.

1/1000th

D. 1/1000th
Explanation
A shutter speed of 1/1000th would best freeze the action because it is the fastest shutter speed among the options given. A faster shutter speed allows for a shorter duration of exposure, which helps to capture a moving subject without any motion blur. In this case, a fast shutter speed would be ideal to freeze the action of the golden retriever jumping to catch the frisbee, ensuring a sharp and clear image.

### You’re taking a picture of a landscape. Which aperture would be best for getting all of it in focus?

• A.

F/16

• B.

F/2

• C.

F/4

• D.

F/8

A. F/16
Explanation
A smaller aperture, such as f/16, would be best for getting all of the landscape in focus. This is because a smaller aperture creates a larger depth of field, meaning that more of the scene will be in focus from the foreground to the background. In contrast, a larger aperture, such as f/2, would create a shallow depth of field, resulting in only a small portion of the landscape being in focus while the rest is blurred.

### Film speed refers to:

• A.

How long it takes to develop film.

• B.

How fast film moves through film-transport system.

• C.

How sensitive the film is to light

• D.

None of these make sense

C. How sensitive the film is to light
Explanation
Film speed refers to how sensitive the film is to light. Film speed is measured by the ISO rating, which indicates the film's sensitivity to light. A higher ISO rating means the film is more sensitive to light, allowing for faster shutter speeds and the ability to shoot in low-light conditions. Conversely, a lower ISO rating means the film is less sensitive to light and requires longer exposure times. Therefore, film speed directly affects the overall exposure and image quality of the photographs taken.

### Depth of Field is controlled by:

• A.

The Focal length of the lens

• B.

The size of the Aperture opening

• C.

The distance between camera and the subject

• D.

All of these

• E.

None of these

D. All of these
Explanation
The depth of field in a photograph is determined by three factors: the focal length of the lens, the size of the aperture opening, and the distance between the camera and the subject. The focal length of the lens affects the magnification and compression of the image, which in turn affects the depth of field. The size of the aperture opening controls the amount of light entering the camera and also affects the depth of field. Lastly, the distance between the camera and the subject determines the perspective and depth of field. Therefore, all of these factors play a role in controlling the depth of field in a photograph.

### What type of lens would give a wider depth of field?

• A.

100mm

• B.

Macro lens

• C.

14mm

• D.

18-200mm

C. 14mm
Explanation
A 14mm lens would give a wider depth of field because it has a wider angle of view compared to the other options. A wider angle of view allows more of the scene to be in focus, resulting in a greater depth of field.

### The dSLR camera is one the most popular types of camera on the market today. dSLR stands for:

• A.

Digital Single Lens Reflex

• B.

Digital Standard Lens Refraction

• C.

Digital Simple Light Recorder

A. Digital Single Lens Reflex
Explanation
The correct answer is "Digital Single Lens Reflex." A dSLR camera is a type of camera that uses a mirror and prism system to reflect light from the lens to the viewfinder, allowing the photographer to see exactly what will be captured in the image. The "digital" part of the term refers to the use of digital sensors to capture the image instead of traditional film. "Single Lens Reflex" indicates that the camera has a single lens for both viewing and capturing the image, and that it uses a reflex mirror to direct light to the viewfinder.

### Which of the following are especially suitable for use in low-light photography?

• A.

Slow ISO setting (ex: 100 ISO)

• B.

Fast shutter speed

• C.

Wide Aperture

• D.

Telephoto lens

C. Wide Aperture
Explanation
Wide aperture is especially suitable for use in low-light photography because it allows more light to enter the camera sensor, resulting in brighter and well-exposed images. A wide aperture (small f-number) creates a shallow depth of field, which can also help to isolate the subject and create a pleasing background blur. Slow ISO setting, fast shutter speed, and telephoto lens do not directly contribute to capturing more light in low-light conditions.

Rate this question:

• 14.

### What determines your depth of field?

• A.

• B.

Aperture, focal length and shutter speed

• C.

Your aperture and the total distance between you and the subject you are focused on

• D.

Your aperture, focal length and the distance from your camera to the subject you are focusing on

D. Your aperture, focal length and the distance from your camera to the subject you are focusing on
Explanation
The depth of field is determined by the combination of the aperture, focal length, and the distance from the camera to the subject being focused on. The aperture controls the amount of light entering the camera and affects the depth of field. A wider aperture (smaller f-number) creates a shallow depth of field, while a narrower aperture (larger f-number) creates a deeper depth of field. The focal length also plays a role, as longer focal lengths tend to have shallower depth of field. Additionally, the distance between the camera and the subject affects the depth of field, with closer distances resulting in a shallower depth of field.

### Out of the apertures listed, which will give you the most light?

• A.

F/22

• B.

F/5.6

• C.

F/2.8

• D.

F/11

C. F/2.8
Explanation
The aperture controls the amount of light that enters the camera. The lower the f-number, the larger the aperture and the more light that is allowed in. Among the given options, f/2.8 has the lowest f-number, indicating a larger aperture and therefore allowing the most light to enter the camera.

Rate this question:

### Which aperture will give you a blurry background?

• A.

F/22

• B.

F/16

• C.

F/2.8

• D.

F/11

C. F/2.8
Explanation
A larger aperture, indicated by a smaller f-number, such as f/2.8, will give you a blurry background. This is because a larger aperture allows more light to enter the camera, resulting in a shallow depth of field. With a shallow depth of field, the subject in focus appears sharp while the background appears blurred.

• A.

F/22

• B.

F/5.6

• C.

F/2.8

• D.

F/11

C. F/2.8
Explanation
A larger aperture, represented by a smaller f-number, allows more light to enter the camera. This means that with f/2.8, the camera can capture more light in a shorter amount of time, enabling a faster shutter speed.

Rate this question:

• 18.

### How is the f/stop calculated/derived?

• A.

By dividing the measured diameter of a particular lens opening into the focal length of the lens

• B.

By multiplying the measured diameter of a particular lens opening into the focal length of the lens

• C.

By the dividing the depth of field and shutter speed of the lens and camera together

A. By dividing the measured diameter of a particular lens opening into the focal length of the lens
Explanation
The f/stop is calculated by dividing the measured diameter of a particular lens opening into the focal length of the lens. This calculation determines the aperture size of the lens, which affects the amount of light that enters the camera and the depth of field in the resulting image. By dividing the diameter into the focal length, photographers can determine the f/stop value, which is used to control the exposure and depth of field in their photographs.
