Matching

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

Descriptions

  1. This better version of the magic wand tool lets you adjust the range of colors you want to select and see the results dynamically.
  2. Any channel beyond the core color channels, used almost exclusively in Photoshop to hold masks.
  3. A tool in the Extract dialog box that automatically adjusts pixels along the edges of the extracted image element.
  4. A special masking blend mode available in the Calculations dialog box that subtracts the luminosity values in the Source 1 channel from those in the Source 2 channel.
  5. A method for creating a selection outline as an independent channel, which you can then edit and save like any other image.
  6. A command that erases the pixels outside an image element and leeches the fringe coloring conveyed by the original background.
  7. This dynamic setting in the Color Range dialog box gradually fades the selection over a range of luminosity values.
  8. Harsh transitions along the edge of a layer that falsely represent your masking efforts and are best fixed when compositing the image against a new background.
  9. A dialog box thumbnail or image that shows an ongoing selection outline as a grayscale image, where white selects and black deselects.
  10. Saves the selection outline as an alpha channel, which can then be saved with any image stored in the TIFF or PSD format.
  11. This feature lets you press the Q key to view and modify the selection outline as a rubylith overlay.
  12. A command in the Image menu that lets you blend two channels to form a new alpha channel that will eventually serve as a mask.
