What does anime cos mean by digging?

Turning over the soil means returning to the picture. For example, in the comic exhibition, I call it returning to the picture when I finish shooting, or the photographer of the comic exhibition calls it returning to the picture when coser finishes shooting.

Usually, photos will be developed relative to Post Bar or official website, and people will return them, and then if they have taken photos, they will receive photos, so sometimes many passers-by will ask for photos.
