PS operation
If you are familiar with the operation of PS, you can directly use PS to make P-pictures. Simply adjust the color and details to achieve the flashing effect easily.
GIF making software
It doesn't matter if you are not familiar with PS, you just need to simply adjust the color of the picture, and then use special GIF production software to make it foolishly. Even a novice can easily get it done!
Dynamic GIF graph
Want a more vivid effect? Try a dynamic GIF diagram. It is interesting and eye-catching to realize the flash effect through the movement of the picture. However, it should be noted that directly generating GIF may affect the image quality. It is suggested to export the SWF file first, and then convert it into GIF with conversion software, which is more effective and keeps the original flavor.
