A processing method has been provided for an exposed silver halide black-and-white negative working sound recording film element, said processing method comprising the steps of processing said sound recording film element in a processing apparatus providing processing ability in a daylight environment, said processing method comprising the steps of developing in a time of less than 20 seconds; fixing in a fixer; rinsing and drying; making use of an automatic processing machine, the mentioned processing steps being followed by a step of controlling black-and-white densitometry, therefor providing the processing machine with a densitometer; further recording in a motion picture color print film and processing therein image area frames originating from an exposed and processed color negative recording film and from (an) optical soundtrack(s) originating from a silver halide black-and-white negative working sound recording film element, wherein said film element has been processed, after having been exposed, by the method as claimed.
Method of processing an exposed silver halide black-and-white negative working sound recording film element, comprising monodispersed cubic silver halide grains rich in silver bromide having an average grain size of less than 0.35 μm and a coefficient of variation of grain size of less than 40%, wherein said grains have been panchromatically sensitized over a wavelength range from 400 nm up to 750 nm, said processing method comprising the steps of processing said sound recording element in a processing apparatus providing processing ability in daylight environment, wherein said processing method comprises the steps of developing in a developer within a time of less than 20 seconds, fixing in a fixer, rinsing and drying.
