How does ps make it clear?

There are many ways to deal with blurred images by PS. The following methods are introduced as follows:

1, Photoshop opens the picture.

2. After opening the picture, click the picture size in the picture.

3. Enter the image size page and change the resolution. Changing the resolution will change the size, so there is no need to change the size.

4. After changing the resolution, select the cube twice in resampling, and then click OK.

5. After the change is confirmed, the picture will become larger and the definition will remain unchanged.

The birth process of photoshop Glenn Knoll, the father of Thomas Knoll, the main designer of Photoshop, is a professor at the University of Michigan and a photography enthusiast. His basement is a darkroom. His two sons, Thomas and John, have been playing darkroom with their father since childhood, but John seems to be more interested in the personal computer just released at that time.

Later, Thomas became fascinated with personal computers and bought an Apple computer (Mac Plus) at 1987 to help his doctoral thesis. 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.
