From Overview 13 (Paths, Layers, Channels, History, and Color Balance): Answer the following questions

    To see the answers, drag your mouse across the question.

    1. Channels show where red, green, and blue are used in an image
    2. White would have information on which channels? All
    3. What is the alpha channel used for? Transparency
    4. One reason for using channels is to create precise masks, for selection.
    5. Paths are a series of connected dots used to select items, but instead of going away, the path is available to reselect later
    6. History allows you to undo previous steps, not just the last step
    7. Levels and Curves are other ways to adjust brightness and contrast
    8. Levels allows you to adjust the tonal range using input sliders
    9. Curves allow you to adjust the input and output with a line, with the  horizontal axis and vertical axis representing the input and output
    10. Threshold removes shades, such as shades of gray
    11. A mask is a selection used to cut, copy or to adjust transparency

      From Overview 14 (video, flash, and copyright)
    13. Video could be defined as photographic images viewed in sequence, often 24-30 frames per second if approaching movie and TV quality
    14. Some video editing packages include Microsoft Movie Maker and Apple iMovie
    15. Some video delivery systems include Microsoft Media Player and Apple Quick Time
    16. Video editing often focuses on scenes and titles
    17. A scene is a series of related images
    18. A scene can be divided into smaller scenes that can be copied or rearranged, by clipping or splitting the scene
    19. A transition is the effect, such as fading, between scenes
    20. Titles are words that appear before or after scenes… in some cases the text can appear over a scene
    21. Microsoft Movie Maker uses either a timeline or a story board to arrange scenes
    22. Flash is used for web animation
    23. Flash has lower bandwidth requirements than traditional video formats
    24. For class you may invoke fair use to use copyrighted images; this is not available outside of class
