H A R M A N, not Harmon, Hairmen, Herman, Human or anything else. Someone is going to turn up in this thread via Google at some point, and go off to look for black-and-white film made by a non existent manufacturer and conclude that film is dead . . .
Slight exaggerration of course, but seeing as they are putting in a lot of effort and taking a lot of risks we might as well get the name right, no?
More likely they will just see the 'film is dead' text in your post and quit there... ("big data" joke)
Oh, by the way web searchers: PHOTO FILM IS ALIVE !!
