  1. Tone Mapping
  2. Exposure Blending
  3. HDR Merging
  4. HDR Stacking
Question 4 Multiple Choice (Single Answer)

What is the purpose of tone mapping in HDR photography?

  1. To reduce the overall brightness of an image
  2. To compress the dynamic range of an image
  3. To increase the contrast of an image
  4. To adjust the colors of an image
Question 5 Multiple Choice (Single Answer)

What are the two main types of tone mapping operators?

  1. Global and Local
  2. Linear and Non-linear
  3. Absolute and Relative
  4. Forward and Inverse
Question 6 Multiple Choice (Single Answer)

What is the difference between global and local tone mapping operators?

  1. Global operators apply the same tone mapping function to the entire image, while local operators apply different tone mapping functions to different parts of the image.
  2. Global operators are more computationally expensive than local operators.
  3. Global operators produce more natural-looking results than local operators.
  4. Local operators are more computationally expensive than global operators.
Question 7 Multiple Choice (Single Answer)

What is the most commonly used global tone mapping operator?

  1. Linear
  2. Sigmoid
  3. Exponential
  4. Logarithmic
Question 8 Multiple Choice (Single Answer)

What is the most commonly used local tone mapping operator?

  1. Histogram Equalization
  2. Adaptive Histogram Equalization
  3. Contrast Limited Adaptive Histogram Equalization
  4. Retinex
Question 9 Multiple Choice (Single Answer)

What is the main advantage of using a local tone mapping operator over a global tone mapping operator?

  1. Local operators produce more natural-looking results.
  2. Local operators are more computationally expensive than global operators.
  3. Local operators can be used to selectively adjust the tone mapping of different parts of an image.
  4. Local operators are less computationally expensive than global operators.
Question 10 Multiple Choice (Single Answer)

What is the main disadvantage of using a local tone mapping operator over a global tone mapping operator?

  1. Local operators produce less natural-looking results.
  2. Local operators are more computationally expensive than global operators.
  3. Local operators can only be used to adjust the tone mapping of the entire image.
  4. Local operators are less computationally expensive than global operators.
Question 11 Multiple Choice (Single Answer)

What is the most important factor to consider when choosing a tone mapping operator?

  1. The dynamic range of the image
  2. The overall brightness of the image
  3. The contrast of the image
  4. The colors of the image
