Exif information in digital photos can be modified, but the modification of shooting parameters is controversial in the circle of photographers, and many people think it is cheating. Some photographers have a low level of photography, but in order to take part in the photo contest, they ask people to process digital photos in the computer.

In order to hide the processing traces of their digital photos, they tamper with the shooting parameters in Exif information at will, which leads to some photo competitions becoming "photo processing competitions" in disguise. But modifying Exif information also has a good side. For example, photographers can add "copyright information" and "user comments" to their digital photos.
