1987, Thomas Noel 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. His brother John works in the film special effects production company "Industrial Light Magic" directed by george lucas, and he is very interested in the program designed by Thomas Knoll.
In the following more than a year, Thomas Knorr and Thomas Knorr replaced Display with a more powerful image editing software. After several renaming, they accepted the suggestion of an exhibitor at an exhibition and finally renamed the program Photoshop.
In the early 1990s, great changes have taken place in the American printing industry, and prepress computerization began to spread. With the addition of CMYK function in Photoshop version 2.0, the printing factory began to hand over the task of color separation to users, and a new industry desktop publishing-DTP came into being.

Adobe Photoshop includes:
Functionally, this software can be divided into image editing, image synthesis, tone correction and functional color effect production. Image editing is the basis of image processing, which can perform various transformations on images, such as enlargement, reduction, rotation, tilt, mirror image and perspective. You can also copy, remove spots, repair and modify damaged images.
Image synthesis is to combine several images into a complete image with clear intention through layer operation and tool application, which is the only way for art design. The drawing tools provided by the software can make foreign images and ideas blend well.
Tone correction can adjust and correct the color of the image, and can also switch between different colors to meet the application of the image in different fields such as web design, printing and multimedia.
The production of special effects in this software is mainly accomplished through the comprehensive application of filters, channels and tools. Including the creation of image special effects and the production of special effects characters, such as oil painting, relief painting, plaster painting, sketch and other commonly used traditional artistic skills can be completed through this software.
