Open the picture of the text to be modified in PS software. When the text needs to be modified, first select the part of the text, fill the background and then enter new text. In order to keep the modified font consistent with the original font, it is necessary to identify the font in the picture, select the horizontal text tool in the toolbox, input the same text content in the picture, and find the same font as the original text in the character panel. For comparison, you can set the text to different colors. After comparing the font, text size and position, temporarily hide the text, and then select the background layer, where the color of the text in the picture is quite different from that in the picture, and you can directly select the text with the magic wand tool.

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 IndustryLightMagic, a film special effects production company 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.
