The Signature

Every film is signed by the manufacturer.

Alongside the frame numbers at the outer edge of every roll of film, each manufacturer places their name, or the film type - or sometimes both. After a quick search through our storage, we found the first proper Ferrania signature used on films from the late 1950s until 1964. After this, the signature was switched to "Ferrania-3M" and later, simply "3M".

The signature is a mask that is inserted into the perforator and exposes directly onto the edge of the film. In a second step, the frame numbers are exposed using a similar mask. The video below shows both of these steps in slow-motion detail (and of course in the light).

During a recent emulsion test, we also tested this signature - with beautiful results! This will be the signature on all FERRANIA P30® ALPHA film.

New Yorker. Crazy for old cameras and analog film. But I love sci-fi. Go figure.
