It’s hard to believe, but Photoshop is nearly 20 years old. The original Apple Macintosh version was written in 1988 by brothers Thomas and John Knoll. The first full version published by Adobe appeared on the Macintosh in 1990. The entire program came on a single 1.44MB floppy disk.
Photoshop has grown and changed over the years, but has always incorporated the latest developments, reinforcing its position as the industry standard for professional image editing. The first Windows version (v2.5) appeared in 1992, layers were introduced in version 3.0 in 1994, multiple undo history in version 5.0 in 1998, and camera RAW support was added with version 7.0 in 2002. The concept of Creative Suite, incorporating and harmonising a whole range of Adobe’s other programs, including ImageReady, Illustrator, InDesign, Premiere, Encore and AfterEffects, was introduced in 2003 along with Photoshop 8.0, known as Photoshop CS. An update, unsurprisingly called Photoshop CS2, came along less than two years later in April 2005, adding many new features such as Smart Objects, a red-eye tool and the invaluable Spot Healing brush.
