Adobe Photoshop, referred to as "PS", is made by Adobe? Image processing software developed and distributed by the system. Photoshop mainly deals with digital images composed of pixels. With its numerous editing and drawing tools, we can edit and create pictures effectively. PS has many functions, including pictures, graphics, text, video, publishing and so on.

Adobe supports Windows operating system, Android and Mac OS, but users of Linux operating system can use Wine to run Photoshop.

1987 Thomas Noel, the chief designer of Photoshop, bought an Apple computer (MacPlus) to help his doctoral thesis. At the same time, Thomas found that the Apple computer at that time could not display black and white images in gray scale, so he wrote a program to display it himself. At this time, his brother john knoll works in the film special effects production company Industry Light Magic directed by george lucas, and he is very interested in Thomas' program.

More than a year later, the two brothers replaced Display with a more powerful image editing program. After many renaming, they accepted the suggestion of an exhibitor at an exhibition and renamed the program Photoshop. At this point, Display/Photoshop has been adjusted in color scale, color balance and saturation. In addition, John also wrote some programs that later became the basis of plug-ins.
