At first, I thought it was a file transfer problem, so I copied it with a USB flash drive. After copying, the picture is still black. The way to open the picture is the default windows photo viewer, the file attribute is JPG format, and the picture is not protected. As far as the picture is concerned, there is no problem, and it can be opened normally in theory. Change the opening mode, use drawing tools and PS to open normally, the color of the picture is normal, and it is no problem to browse the picture.
: 1. Image quality problem, the picture may have errors in the setting of resolution and gray value, but the drawing tool and PS can be browsed during production, and this reason can be ruled out; 2. The pictures stored after PS are wrong, and the related values of the pictures stored after PS are wrong. After adjusting the value, the picture problem still exists, so this possibility is ruled out; 3.PS software is pirated or the program has loopholes or errors. After copying the picture to another computer, the picture looks normal, which also excludes this reason; 4.windows photo viewer program error, download other JPG format pictures from the computer and display them normally, and eliminate this reason; 5. There are loopholes or defects in computer settings.
