Abstract: Photographic film having an image and means for receiving coded indicia is viewed in a film video player to produce a television signal for displaying the film image. The film video player includes cropping means for selectively varying the magnification of the displayed image and for selectively translating a magnified displayed image vertically and/or horizontally, and recording means for applying coded indicia to the film, specifying a selected magnification and vertical and horizontal translation. A printer for making reflection prints from the photographic film includes reading means for reading the coded indicia on the film and cropping means for varying the magnification of the printed image, and translating a magnified image vertically and/or horizontally, in response to the coded indicia.

Abstract: Electronic strobe flash apparatus includes a first energizable flashtube arranged to project light for reflection from a surface to illuminate a scene indirectly, and a second energizable flashtube arranged to illuminate the scene directly. A sequencing circuit controls the energization of both flashtubes so that the ratio of the indirect flash to the direct flash reflected from the scene is constant in instances where the reflected flash is above a minimum level. For this purpose, a light-sensitive circuit, arranged to sense light reflected from the scene, is coupled to the sequencing circuit. The sequencing circuit causes the indirect flash to be produced first. The light-sensitive circuit causes the sequencing circuit to (1) quench the first flashtube to extinguish the indirect flash, and (2) fire the second flashtube to produce the direct flash, when the light-sensitive circuit senses that a predetermined fraction of a desired total amount of light has been reflected from the scene.

Abstract: A quenchable electronic strobe flash unit has a light-responsive integrating circuit for causing the light emitted by a flashtube to be terminated when the integrating circuit senses a predetermined amount of light. A light-level sensing circuit measures the intensity of the ambient light. A threshold-setting circuit, responsive to the sensing circuit, causes the amount of light needed to be sensed by the integrating circuit for terminating the flash in bright ambient light to be, for example, twenty-five percent of the amount of light required to be sensed for terminating the flash in low ambient light. Thus, for subjects within the maximum range of the flash, when ambient light is relatively low, a desired exposure is due primarily to flash light, and when ambient light is relatively high, a selected portion of the desired exposure is attributable to flash light which is, for example, twenty-five percent of the full-flash light output.
