Photography Techniques and Lenses Questions
Which of the following term is not associated with a lens?
-
Aperture
-
Focal length
-
Principal focus
-
Momentum
D
Correct answer
Explanation
The term momentum is not associated with a lens. It is the product of mass and velocity of a body.
What kind of lens is used in making a pinhole camera ?
-
Concave lens
-
Convex lens
-
Concavo-convex lens
-
No lens is used
D
Correct answer
Explanation
A pinhole camera is a simple camera without a lens but with a tiny aperture, a pinhole – effectively a light-proof box with a small hole in one side.
-
shutter speed
-
aperture
-
focus
-
aberration
B
Correct answer
Explanation
The aperture is the adjustable opening within the lens that controls the amount of light passing through to the camera sensor.
-
f0.85 - f3.5
-
f4 - f5.6
-
f8 - f11
-
f16 - f32
C
Correct answer
Explanation
Landscape photography typically requires a deep depth of field to keep both foreground and background in focus. f8 to f11 are standard apertures to achieve this sharpness.
-
Contrast
-
Depth of Field
-
Lens Speed
-
Cropping
B
Correct answer
Explanation
Depth of field refers to the range of distance within a photo that appears acceptably sharp. It is controlled by aperture, focal length, and distance to the subject.
-
Shutter
-
Aperture
-
Pentaprism
-
Sensor
B
Correct answer
Explanation
The aperture is the opening in the lens that controls how much light reaches the sensor. It is measured in f-stops, where smaller numbers represent larger openings.
C
Correct answer
Explanation
Av stands for Aperture Value (or Aperture Priority). In this mode, the user selects the aperture, and the camera automatically calculates the shutter speed.
A
Correct answer
Explanation
A smaller f-number (like f1.2) corresponds to a wider aperture, which results in a shallower depth of field. Larger f-numbers (like f11) result in a deeper depth of field.
Which aperture setting results in a shallow depth of field?
A
Correct answer
Explanation
A shallow depth of field is achieved with a wide aperture, which is denoted by a small f-number. In this case, f/1.4 is the widest aperture setting, resulting in a shallow depth of field.
Which aperture setting results in a deep depth of field?
D
Correct answer
Explanation
A deep depth of field is achieved with a narrow aperture, which is denoted by a large f-number. In this case, f/11 is the narrowest aperture setting, resulting in a deep depth of field.
Which aperture setting is commonly used for landscape photography?
D
Correct answer
Explanation
In landscape photography, a narrow aperture (large f-number) is often used to achieve a deep depth of field, ensuring that both the foreground and background elements are in focus.
Which aperture setting is commonly used for portrait photography?
A
Correct answer
Explanation
In portrait photography, a wide aperture (small f-number) is often used to create a shallow depth of field, isolating the subject from the background and drawing attention to them.
What is the term used to describe the point at which the lens is focused?
-
Focal point
-
Focus point
-
Plane of focus
-
Depth of field
A
Correct answer
Explanation
The focal point is the point in space at which the lens is focused. It is the point where the light rays converge after passing through the lens.
What is the term used to describe the range of distances that appear in focus in an image?
-
Focal point
-
Focus point
-
Plane of focus
-
Depth of field
D
Correct answer
Explanation
Depth of field is the range of distances that appear in focus in an image. It is determined by the aperture setting and the focal length of the lens.
Which camera feature allows for selective focus, blurring the background while keeping the subject sharp?
-
Aperture
-
Shutter speed
-
ISO
-
Depth of field
A
Correct answer
Explanation
Aperture, represented by f-stops, controls the depth of field. A wider aperture (lower f-stop) creates a shallow depth of field, blurring the background and emphasizing the subject.
