| If the B&W film isn't indicated as C-41 compatable (or compatable with other manufacturers versions of the C-41 process), then it cannot be put through the C-41 process with success.
The C-41 process does not leave any silver image on the film, so when a silver image B&W film is processed in C-41 process, the film is completely stripped of silver and comes out clear.
Note that you can cross process E-6 slide film in C-41 chemistry and get a non masked colour negative. |
