What is the primary purpose of color correction in image editing?

  1. To adjust the overall color balance of an image

  2. To remove unwanted color casts

  3. To enhance the contrast and saturation of an image

  4. To fix exposure problems

Show answer
Correct Option: A
Explanation:

Color correction is primarily used to adjust the overall color balance of an image, ensuring that the colors appear natural and accurate.

What is white balance, and how does it affect the colors in an image?

  1. White balance is the adjustment of the color temperature of an image to make white objects appear white

  2. White balance is the adjustment of the contrast and saturation of an image to make colors appear more vibrant

  3. White balance is the adjustment of the exposure of an image to make it brighter or darker

  4. White balance is the adjustment of the sharpness of an image to make details appear more defined

Show answer
Correct Option: A
Explanation:

White balance is the adjustment of the color temperature of an image to ensure that white objects appear white under different lighting conditions.

What is color temperature, and how does it relate to white balance?

  1. Color temperature is the measurement of the warmth or coolness of a light source

  2. Color temperature is the measurement of the brightness of a light source

  3. Color temperature is the measurement of the hue of a light source

  4. Color temperature is the measurement of the saturation of a light source

Show answer
Correct Option: A
Explanation:

Color temperature is the measurement of the warmth or coolness of a light source, expressed in degrees Kelvin (K). It determines the overall color cast of an image.

What is the difference between contrast and saturation in image editing?

  1. Contrast is the difference between the lightest and darkest areas of an image, while saturation is the intensity of the colors

  2. Contrast is the difference between the warmest and coolest colors in an image, while saturation is the intensity of the colors

  3. Contrast is the difference between the brightest and dullest colors in an image, while saturation is the intensity of the colors

  4. Contrast is the difference between the sharpest and blurriest areas of an image, while saturation is the intensity of the colors

Show answer
Correct Option: A
Explanation:

Contrast is the difference between the lightest and darkest areas of an image, while saturation is the intensity of the colors.

What is the purpose of using a color wheel in color correction?

  1. To select complementary colors for enhancing the contrast of an image

  2. To select analogous colors for creating a harmonious color scheme

  3. To select monochromatic colors for creating a unified look

  4. To select triadic colors for adding visual interest

Show answer
Correct Option: A
Explanation:

A color wheel is used in color correction to select complementary colors, which are opposite each other on the wheel. Complementary colors can be used to enhance the contrast of an image by creating a strong visual contrast.

What is the technique of split toning in color correction?

  1. Applying different colors to the highlights and shadows of an image

  2. Applying different colors to the warm and cool tones of an image

  3. Applying different colors to the light and dark areas of an image

  4. Applying different colors to the saturated and desaturated areas of an image

Show answer
Correct Option: A
Explanation:

Split toning is a technique in color correction where different colors are applied to the highlights and shadows of an image. This can be used to create a variety of effects, such as adding warmth to the highlights or creating a cool, moody look.

What is the purpose of using curves in color correction?

  1. To adjust the overall contrast of an image

  2. To adjust the brightness and darkness of an image

  3. To adjust the color balance of an image

  4. To adjust the saturation of an image

Show answer
Correct Option: A
Explanation:

Curves are used in color correction to adjust the overall contrast of an image. By manipulating the curve, you can control the distribution of tones in the image, making it brighter or darker, or increasing or decreasing the contrast.

What is the difference between hue, saturation, and lightness in color theory?

  1. Hue is the color itself, saturation is the intensity of the color, and lightness is the brightness of the color

  2. Hue is the color itself, saturation is the purity of the color, and lightness is the darkness of the color

  3. Hue is the color itself, saturation is the warmth or coolness of the color, and lightness is the brightness of the color

  4. Hue is the color itself, saturation is the dullness or vibrancy of the color, and lightness is the brightness of the color

Show answer
Correct Option: A
Explanation:

Hue is the color itself, saturation is the intensity of the color, and lightness is the brightness of the color. These three elements together define the appearance of a color.

What is the purpose of using a histogram in color correction?

  1. To analyze the distribution of tones in an image

  2. To adjust the overall contrast of an image

  3. To adjust the color balance of an image

  4. To adjust the saturation of an image

Show answer
Correct Option: A
Explanation:

A histogram is used in color correction to analyze the distribution of tones in an image. It shows the number of pixels at each brightness level, allowing you to see if the image is too bright, too dark, or has a good balance of tones.

What is the technique of color grading in color correction?

  1. Adjusting the overall color balance of an image

  2. Applying different colors to the highlights and shadows of an image

  3. Creating a unified color scheme for an image

  4. Adjusting the contrast and saturation of an image

Show answer
Correct Option: C
Explanation:

Color grading is a technique in color correction where a unified color scheme is created for an image. This involves adjusting the colors, contrast, and saturation to achieve a consistent and cohesive look.

What is the purpose of using a color lookup table (LUT) in color correction?

  1. To apply a specific color grade to an image

  2. To adjust the overall color balance of an image

  3. To analyze the distribution of tones in an image

  4. To adjust the contrast and saturation of an image

Show answer
Correct Option: A
Explanation:

A color lookup table (LUT) is used in color correction to apply a specific color grade to an image. A LUT is a mathematical table that maps input colors to output colors, allowing you to quickly and easily apply a desired color look to your image.

What is the difference between additive and subtractive color mixing?

  1. Additive color mixing is used for digital images, while subtractive color mixing is used for printed images

  2. Additive color mixing is used for mixing light, while subtractive color mixing is used for mixing pigments

  3. Additive color mixing is used for mixing warm colors, while subtractive color mixing is used for mixing cool colors

  4. Additive color mixing is used for mixing saturated colors, while subtractive color mixing is used for mixing desaturated colors

Show answer
Correct Option: B
Explanation:

Additive color mixing is used for mixing light, where different colors of light are combined to create new colors. Subtractive color mixing is used for mixing pigments, where different colors of pigments are combined to create new colors.

What is the purpose of using a soft proof in color correction?

  1. To preview how an image will look when printed

  2. To adjust the overall color balance of an image

  3. To analyze the distribution of tones in an image

  4. To adjust the contrast and saturation of an image

Show answer
Correct Option: A
Explanation:

A soft proof is used in color correction to preview how an image will look when printed. It allows you to see how the colors will appear on a specific printer or paper type, helping you to make adjustments to the image before printing.

What is the technique of dodging and burning in color correction?

  1. Lightening specific areas of an image

  2. Darkening specific areas of an image

  3. Adjusting the overall color balance of an image

  4. Adjusting the contrast and saturation of an image

Show answer
Correct Option: A
Explanation:

Dodging and burning is a technique in color correction where specific areas of an image are lightened or darkened. Dodging is used to lighten areas, while burning is used to darken areas.
