摘要:
The invention concerns a method of, and an apparatus for, photographically making positive pictures from individual frames of motion-picture films, film strips and microfilms. The image from a respective selected film frame is exposed onto a self-developing ("instant-picture") film sheet which is then developed to produce a positive paper picture of this image.

A casing, particularly for roll film cartridges, includes a hollow housing having a chamber for closely receiving a film cartridge and a channel which communicates with the chamber. The channel is operative for receiving a length of roll film which extends out of the cartridge when the latter is inserted into the chamber. The channel extends tangentially to the chamber and has at least one flat inner surface along which the length of roll film can extend to be held in flat condition.

The reproducing apparatus, such as a motion-picture film projector, stops recording medium transport in response to interrupt-transport frame markings on the recording medium and reproduces the thusly marked image frames as still images. Interrupt-transport frame markings are provided at the terminal frame of each motion-picture scene on the recording medium, or at each still-shot image frame on the recording medium, or both. The user of the reproducing apparatus can select automatic reproduction of motion-picture scenes interspersed with automatic still reproduction of still shots, and can additionally select automatic still reproduction of the terminal frame of each motion-picture scene.

A method for processing photographic silver halide materials with aqueous processing baths which are replenishedduring processing, in which at least one chemical substance in the form of a plurality of solid bodies of geometrically defined shape and of the same size and composition is added to replenish at least one processing bath, is distinguished by a low consumption of chemicals and by a minimal accumulation of overflow for subsequent disposal.
摘要:
The user of a motion-picture camera selects between motion-picture and single-exposure operation, and presses a release member to initiate shooting, letting go of it to terminate motion-picture shooting. Each time the user lets go of the release member, an internal device provides an interrupt-transport marking alongside the just exposed film frame, or phase shifted relative thereto. Alternatively, the interrupt-transport marking is provided the next time the user presses the release member. In this way, the terminal frame of each motion-picture scene, and each and every one of the interspersed single-exposure shots, is provided with an interrupt-transport frame marking. Thus, if the film is run through a reproducing apparatus provided with a marking detector, detection of each interrupt-transport marking during motion-picture reproduction causes the terminal frame of each motion-picture scene, and also each one of the still shots, to be persistently reproduced as a still image. The interrupt-transport markings could alternatively be provided by such a device in a reproducing apparatus.
