What is the relationship between aperture, shutter speed, and ISO in terms of exposure?

  1. Aperture controls the amount of light entering the lens, shutter speed controls the duration of light exposure, and ISO controls the sensitivity of the sensor.

  2. Aperture controls the depth of field, shutter speed controls the motion blur, and ISO controls the overall brightness of the image.

  3. Aperture controls the sharpness of the image, shutter speed controls the color temperature, and ISO controls the contrast of the image.

  4. Aperture controls the white balance, shutter speed controls the exposure, and ISO controls the dynamic range of the image.


Correct Option: A
Explanation:

In cinematography, aperture, shutter speed, and ISO are the three main factors that determine the exposure of an image. Aperture controls the amount of light entering the lens, shutter speed controls the duration of light exposure, and ISO controls the sensitivity of the sensor to light.

What is the difference between underexposure and overexposure in cinematography?

  1. Underexposure occurs when too little light reaches the sensor, resulting in a dark image, while overexposure occurs when too much light reaches the sensor, resulting in a bright image.

  2. Underexposure occurs when the aperture is too small, while overexposure occurs when the aperture is too large.

  3. Underexposure occurs when the shutter speed is too fast, while overexposure occurs when the shutter speed is too slow.

  4. Underexposure occurs when the ISO is too low, while overexposure occurs when the ISO is too high.


Correct Option: A
Explanation:

Underexposure and overexposure are two common problems that can occur in cinematography when the camera's exposure settings are not properly adjusted. Underexposure occurs when too little light reaches the sensor, resulting in a dark image, while overexposure occurs when too much light reaches the sensor, resulting in a bright image.

What is the dynamic range of a camera?

  1. The ratio between the brightest and darkest parts of an image that the camera can capture without losing detail.

  2. The range of colors that the camera can reproduce.

  3. The sharpness of the image that the camera can produce.

  4. The amount of noise that the camera produces.


Correct Option: A
Explanation:

The dynamic range of a camera is the ratio between the brightest and darkest parts of an image that the camera can capture without losing detail. A camera with a high dynamic range can capture a wider range of tones, from bright highlights to dark shadows, without losing detail in either area.

What are some factors that affect the dynamic range of a camera?

  1. The sensor size, the lens quality, and the lighting conditions.

  2. The camera's aperture, shutter speed, and ISO settings.

  3. The camera's white balance and color temperature settings.

  4. The camera's focus and zoom settings.


Correct Option: A
Explanation:

The dynamic range of a camera is primarily affected by the sensor size, the lens quality, and the lighting conditions. A larger sensor, a higher-quality lens, and better lighting conditions will generally result in a higher dynamic range.

How can cinematographers use exposure and dynamic range to create specific visual effects?

  1. By underexposing or overexposing the image to create a dramatic or stylized look.

  2. By using a shallow depth of field to focus attention on a specific subject.

  3. By using a slow shutter speed to create motion blur.

  4. By using a high ISO to reduce noise in low-light conditions.


Correct Option: A
Explanation:

Cinematographers can use exposure and dynamic range to create specific visual effects by underexposing or overexposing the image to create a dramatic or stylized look. For example, underexposing an image can create a dark and moody atmosphere, while overexposing an image can create a bright and airy look.

What is the difference between exposure latitude and dynamic range?

  1. Exposure latitude is the range of exposure values that a camera can capture without losing detail, while dynamic range is the ratio between the brightest and darkest parts of an image that the camera can capture without losing detail.

  2. Exposure latitude is the range of aperture values that a camera can use without losing detail, while dynamic range is the range of shutter speed values that a camera can use without losing detail.

  3. Exposure latitude is the range of ISO values that a camera can use without losing detail, while dynamic range is the range of white balance values that a camera can use without losing detail.

  4. Exposure latitude is the range of focus values that a camera can use without losing detail, while dynamic range is the range of zoom values that a camera can use without losing detail.


Correct Option: A
Explanation:

Exposure latitude is the range of exposure values that a camera can capture without losing detail, while dynamic range is the ratio between the brightest and darkest parts of an image that the camera can capture without losing detail. Exposure latitude is typically measured in stops, while dynamic range is typically measured in decibels (dB).

How can cinematographers use exposure and dynamic range to create a sense of depth in an image?

  1. By using a shallow depth of field to focus attention on a specific subject.

  2. By using a wide depth of field to keep everything in focus.
