Multiple choice

What is the Kelvin scale used for in white balance adjustment?

  1. To measure the color temperature of light

  2. To adjust the contrast of the image

  3. To control the exposure of the image

  4. To reduce noise in the image
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Kelvin scale is used to measure the color temperature of light, which is expressed in degrees Kelvin (K). Different light sources have different color temperatures, and the Kelvin scale helps photographers determine the appropriate white balance setting to accurately capture the colors under a specific lighting condition.

Multiple choice

What is the purpose of using a gray card in white balance adjustment?

  1. To measure the color temperature of light

  2. To calibrate the camera's white balance

  3. To reduce noise in the image

  4. To enhance the contrast of the image
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A gray card is a neutral gray surface that reflects light evenly across the visible spectrum. It is used to calibrate the camera's white balance by capturing an image of the gray card under the same lighting conditions as the subject. This allows the camera to accurately determine the neutral white point and adjust the colors accordingly.
