ABSTRACT:
A flashing device attachable to a motion picture camera having a body provided with an objective lens aperture and with at least two magazine apertures over one of which may be detachably mounted a film magazine. The camera comprises a driving mechanism inside its body to move the film stored in the magazine and passing it through one magazine aperture over which the magazine is mounted, in front of the lens aperture in order to expose the successive frames of this film to the light of a scene to be recorded. A casing provided with an opening closed by a ground glass is detachably mounted onto the body of the camera over the other magazine aperture with the opening of the casing facing the other magazine aperture. A lamp is mounted inside the casing for directing light onto the ground glass closing the opening of the casing and therefrom through this opening and its facing aperture, onto the film moving through the body of the camera in order to subject the film to a supplemental uniform exposure. A photocell is mounted inside the casing so as to face the ground glass for measuring directly onto the surface of the glass the intensity of the light directed thereto by the lamp. A diagram is also provided for adjusting the intensity of the light directed onto the ground glass by the lamp. If desired, or colormeter may be mounted inside the casing for measuring the color of the light directed onto the ground glass by the lamp and a set of fitters may be used for adjusting the color of the light directed onto the ground glass by the lamp.
