? Introduction to PS

Adobe Photoshop, referred to as "PS", is an image processing software developed and released by Adobe Systems. 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.

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.
