Match the key concepts in the numbered list to the left with the letter of the phrase below that best describes it.

  2. The three brightness ranges that you can edit independently using the Levels command.
  3. This command lets you darken highlights and lighten shadows, just what you need when correcting flash photos.
  4. The best tool for manually adjusting the brightness and increasing the contrast of an image on a channel-by-channel basis.
  5. Expressed as an exponent, this value multiplies the brightness of an image to lighten or darken midtones.
  6. This command both corrects and neutralizes the shadows, highlights, and midtones in an image, making it the most useful of Photoshop’s automatic levels-correction functions.
  7. A bar graph representation of all brightness values and their distribution in an image.
  8. This command automatically corrects the shadows and highlights of an image but leaves the color balance unchanged.
  9. An independent grayscale image that Photoshop colorizes and mixes with other images to produce a full-color composite.
  10. The one command that lets you pinpoint a specific color in an image and make it lighter or darker; best suited to reducing contrast.
