Adobe Illustrator was first developed for the Apple Macintosh in December 1986 (shipping in January 1987) as a commercialization of Adobe’s in-house font development software and PostScript file format. Adobe Illustrator is the companion product of Adobe Photoshop. Photoshop is primarily geared toward digital photo manipulation and photo realistic styles of computer illustration, while Illustrator provides results in the typesetting and logo graphic areas of design. Adobe Illustrator is a vector graphics editor developed and marketed by Adobe Systems. The latest version, Illustrator CC, is the seventeenth generation in the product line.
Adobe Photoshop is a raster graphics editor developed and published by Adobe Systems for Windows and Mac OS. Photoshop was created in 1988 by Thomas and John Knoll. Since then, it has become the de facto industry standard in raster graphics editing, such that the word “photoshop” has become a verb as in “to Photoshop an image,” “photo shopping,” and “photoshop contest,” etc. It can edit and compose raster images in multiple layers and supports masks, alpha compositing and several color models including RGB, CMYK, Lab color space, spot color and duotone. Adobe Photoshop CC is the latest version of Adobe Photoshop.
