What is Adobe Photoshop?

Adobe Photoshop is a powerful raster graphics editor developed by Adobe Inc. It is primarily used for editing images, creating digital artwork, graphic design, and photo manipulation. Photoshop allows users to modify individual pixels, making it ideal for highly detailed image work.

Launched in 1988 by Thomas and John Knoll, Photoshop has evolved from a basic photo editing tool to a creative industry standard used by professionals in fields like photography, advertising, publishing, UI/UX, and motion graphics.

A Brief History of Photoshop

Photoshop was originally created by Thomas Knoll, a Ph.D. student, as a simple image display program called Display. His brother, John Knoll, an employee at Industrial Light & Magic, saw potential in it as a full-fledged image editor.

They sold the license to Adobe, and in 1990, Adobe Photoshop 1.0 was released. Since then, it has become the flagship product of Adobe Creative Cloud, used by millions of creatives worldwide.

Key milestones:

• 1990: Photoshop 1.0 released for Mac
• 2003: Adobe introduces the Creative Suite (CS)
• 2013: Launch of Adobe Creative Cloud (subscription model)
• 2020s: Integration of AI tools like Adobe Sensei and neural filters

Understanding Raster vs Vector

Photoshop is a raster-based program, which means it works with pixel-based images. This is ideal for editing photos, painting, and manipulating visuals with high detail.

It differs from vector-based programs like Adobe Illustrator, which are better for logos and scalable designs.

Raster images (like JPEGs or PNGs) lose quality when scaled. Photoshop allows you to work at high resolutions to avoid this issue.
