Adobe Photoshop turns twenty

Over its 20-year history, Photoshop has evolved significantly from a simple original display program to a wildly popular application that has over 10 million users worldwide. With each release, Adobe has introduced technological innovations that defy the impossible. Layers, introduced in Photoshop 3.0, gave designers the ability to create complex compositions easier than ever before. The Healing Brush, another groundbreaking feature introduced in Photoshop 7.0, allowed users to magically retouch images by seamlessly removing blemishes and wrinkles, while preserving lighting and texture. Photoshop tools like crop, eraser, blur and dodge and burn have become part of the creative vernacular worldwide.
