Images

1. Differences between bitmap and vector

1.1. Bitmaps - use more memory - bigger file size - download slow - draw slow - not easily scalable and resizeable

1.2. Vectors - use less memory - smaller file size - download faster - draw faster - easy to scalable and resizable

2. Colors and Palettes

2.1. Natural light and color - Additive color -Subtractive color - Color models

2.2. Color palettes - also call " color lookup tables ", or CLUTs on    Macintosh - common palettes are 1-, 4-, 8-, 16-, and 24    bits deep

2.3. Dithering - process whereby the color value of each pixel    is changed to the closest matching color    value in target palette

3. Image file type used

3.1. Macintosh formats

3.2. Windows formats

3.3. Cross-platform formats

3.4. Image file compression

4. Still images are generated in 2 ways

4.1. Bitmaps - simple matrix of tiny dots that form an image    and displayed on screen or printed - can have varying bit and color depth - made up of individual dots or picture    elements known as pixels or pels

4.1.1. Bitmap Software - Adobe's Photoshop and Illustrator - Corel's Painter and CorelDraw

4.2. Vectors

4.2.1. Victors-drawn images are used in: - Computer-aided design ( CAD ) - Graphic artists designing - 3-D animation programs

5. Legal rights to protecting use of image

5.1. Public domain images - for sharing purpose, everyone can download    for free

5.2. Royalty-free images - need to make purchase and then used without paying addition license fees

5.3. Right-managed images - require you negotiate with right    holder regarding terms for using the    image

6. Features of 3-D application

6.1. Modeling - placing all the elements into 3-D space

6.2. Extrusion - The shape of a plane surface extends some    distance

6.3. Lathing - A profile of the shape is rotated around a    defined axis
