Should paid model photographers return to the picture?

Either sign a contract in advance and say that you want to give the film, otherwise it is normal for the photographer to basically leave one hand. If you really want a negative, it is possible for photography to output it to you in dng format (theoretically). It's just that the space is a little smaller in the later period, but it basically meets your needs. (add a note at the end. The comment area says that some cameras can set copyright ownership, camera serial number and so on. But these can be changed after being eaten raw. These functions belong to the typical function of preventing gentlemen and villains. ).
