1. Understanding natural light and color Light comes from an atom where an electron passes from a higher to a lower energy level.
2. Additive color Subtractive color Color models
3. Color palettes
4. Palettes are mathematical tables that define the color of pixels displayed on the screen.
5. Dithering
6. Dithering is a process whereby the color value of each pixel is changed to the closest matching color value in the target palette.
7. Making Still Images Capturing and editing images： Capturing and storing images directly from the screen is another way to assemble images for multimedia. Users can scan images from conventional sources and make necessary alterations and manipulations.
8. images are generated in two ways:
9. Vector-drawn images Computer-aided design (CAD) programs needed by architects and engineers
10. Bitmaps A bitmap is a simple matrix of the tiny dots that form an image and are displayed on a screen or printed.
11. Vector-drawn graphics Applications of vector-drawn object How vector-drawn images work Vector-drawn images versus bitmaps
12. 3-D drawing and rendering Rendering - Use of intricate algorithms to apply user-specified effects Takes many hours for a single image
13. Image File Types Used in Multimedia Macintosh formats Windows formats Cross-platform formats
