In 1987, a Student Set Out to Fix a Mac Problem. The Code Spiraled Out of Control, and He Ended up Creating "Photoshop"

Key Points:

• Thomas Knoll developed the initial image-processing utility "Display" in 1987 to simulate grayscale on a black-and-white Macintosh Plus, which eventually became the foundation of Adobe Photoshop.
• John Knoll, Thomas's brother and an effects artist at Industrial Light and Magic, requested integrating separate image-processing tools into one application, leading to Photoshop's cohesive workspace.
• Drawing on photographic darkroom experience, Thomas introduced the Levels adjustment feature to address monitor gamma inconsistencies, blending analog techniques with digital editing.
• After multiple rejections from tech companies, Adobe recognized Photoshop’s potential and launched version 1.0 in 1990 for Macintosh, targeting professional design and publishing markets with innovative tools like the Lasso and Magic Wand.
• Photoshop's widespread adoption accelerated with the rise of the public web, affordable inkjet printers, and consumer digital cameras, enabling seamless digital photography workflows that transformed image editing and printing.
