System and method for digital film development using visible light

A method for preparing a roll of film for being processed, comprising:

• predictively positioning a tongue of a roll of film relative to a film magazine,
• wherein the roll of film is contained in the film magazine;
• performing a tongue extraction operation for extracting a tongue of the roll of film through a light-proof window of the film magazine;
• rotating the roll of film through a prescribed angle in response to the tongue of said film remaining in the film magazine after performing the first tongue extraction operation;
• and
• repeating the second tongue extraction operation.

A method of predictively positioning a tongue of a roll of film, comprising:

• rotating a roll of film contained in a film magazine, wherein the film magazine includes a light-proof window therein;
• capturing an acoustic pattern generated by the roll of film in response to rotating the roll of film;
• correlating the acoustic pattern to a predicted angular position of the roll relative to the light-proof window;
• and
• rotating the roll of film to the predicted angular position, wherein a tongue of said film is predicted to be positioned in a desired orientation relative to the light-proof when the roll of film is at the predicted angular position.
