Vector and raster

• raster based images

• 2-Made of pixels
• 3-Large file sizes
• 4-Save photographic information (gradiation, colors) more accurately
• 5-Distort when scaled up (stretching pixels results in a grainy image)
• 6-Common file-saving formats: jpg

• vector based images
• 1-Common software: vector software (ex.Adobe Illustrator)

• 3-Small file sizes
