The First Version of Adobe Photoshop: A Detailed History

Introduction

Adobe Photoshop is now a global standard in digital design and photo editing, but its journey began with a very simple version. Understanding the first version of Photoshop helps us appreciate how far this powerful software has evolved.

Who Created the First Photoshop?

The origins of Photoshop trace back to two brothers:

• Thomas Knoll
• John Knoll

In 1987, Thomas Knoll, a Ph.D. student at the University of Michigan, started developing a program called “Display”. It was designed to show grayscale images on a monochrome monitor.

His brother John Knoll, who worked at Industrial Light & Magic, saw the potential of the program and encouraged him to expand it into a full image-editing tool.

From “Display” to Photoshop

The software was later renamed ImagePro, and eventually became Photoshop. The Knoll brothers worked together to enhance its features, making it capable of editing digital images in more advanced ways.

In 1988, they began trying to sell the program to companies. Eventually, Adobe Inc. agreed to distribute it.

Release of Photoshop 1.0

The first official version, Photoshop 1.0, was released in February 1990, exclusively for Macintosh computers.

Key Details:

• Release Year: 1990
• Platform: Apple Macintosh
• Developer: Adobe Inc.
• Creators: Thomas Knoll & John Knoll

Features of Photoshop 1.0

Compared to today’s version, Photoshop 1.0 was very basic, but revolutionary for its time.

Main Features Included:

• Basic image editing tools
• Cropping and resizing images
• Simple color adjustments
• Selection tools
• Basic retouching capabilities

At that time, features like layers (which are essential today) were not yet available—they were introduced in later versions.

Why Photoshop 1.0 Was Revolutionary

Even though it seems simple today, Photoshop 1.0 was groundbreaking because:

1. Digital Image Editing Was New

Before Photoshop, most image editing was done manually or with very limited software.

2. User-Friendly Interface

It introduced a more accessible way for designers and photographers to edit images digitally.

3. Foundation for Future Innovation

Photoshop 1.0 laid the groundwork for all future versions and modern graphic design tools.

Limitations of the First Version

Photoshop 1.0 had several limitations:

• No support for layers
• Limited tools and filters
• Only worked on Macintosh
• Less advanced color editing

Despite these limitations, it was a huge step forward in digital creativity.

Evolution After Version 1.0

After its initial release, Adobe continued to improve Photoshop by adding:

• Layers (introduced in Photoshop 3.0)
• Advanced filters and effects
• Support for Windows systems
• 3D design and AI tools (in modern versions)

Today, Photoshop is used worldwide for professional design, photography, and digital art.

Conclusion

The first version of Adobe Photoshop, released in 1990, marked the beginning of a new era in digital design. What started as a simple grayscale display program by Thomas Knoll and John Knoll has grown into one of the most powerful creative tools in the world.

Understanding its early history not only gives us insight into its development but also inspires new designers to appreciate the evolution of technology.
