  • the camera (and film) maximize quality and efficiency by providing a new sequence of events and approaches as each frame of unexposed film (or other emulsified material) moves into a film gate for exposure, by way of light related from a capture lens.
  • film prior to exposure, film undergoes an expansion process, such as by way of a film surface affecting device that, for example, is globe-shaped, and that makes contact with the film from the side of the film that is reverse to the side having emulsion for exposure.

  • correcting optics may be subsequently employed to reconfigure stored (or recorded) visuals for desired display, aspect ratio, 2 dimensional display systems and related options geared to potential final display intentions.
  • optical image conversion approaches include anamorphic lens systems, which record a visual which is first distorted, and thereafter "undistorted" by optics designed to adjust for the initial distortion imposed for proper recording onto media with a different aspect ratio than the full, undistorted scene capture through the camera lens.
  • a device releases a compressed amount of gas, such as oxygen, to expand or otherwise inflate a surface of the pre-positioned film.
  • gas such as oxygen
  • Air preferably allows for fast, intermittent "inflation" of the film surface, like a balloon, without making physical contact with the film which can potentially mark or damage the film.

  • the size of the intended maximum area of exposable emulsion which may be a coating or embodiment of the expandable surface itself as an aspect of the elastic or variable material, is not revealed and/employed until the air (or other penetrating object in an alternative embodiment) expands the surface to something similar or identical, to the expansion of the surface experienced when the emulsion was first incorporated or coated onto it.
  • a selectively air-tight seal between the compressed air means and the film gate (or film surface) may be employed for controlled, consistent expansion of the expandable film, emulsion, or other photosensitive bearing material.
  • a transparent surface in the ideal shape of the emulsion for exposure might be involved, to contain the inflated emulsion surface, for example, in an identical size and position for each subsequent exposure, for image continuity.

  • the present invention may provide a new aesthetic and technical range of options relying less, or not at all, on optical distortion of captured and/or displayed images to achieve a desired aesthetic effect. Namely, capture of a visual in nearly if not the same three-dimensional aspect, or display ratio, as the eventual screening means will utilize.
  • the "bubble" of emulsion exposed by the present expandable emulsion exposure system, and film media product(s) may be selectively similar in curvature and spherical shape to that of the eventual screen on which the visuals will be displayed, reducing need for familiar extreme optical impositions and reconverting (distorting) of visual data for recording and screening from two-dimensional filmed images, and images screened from film.
  • double-sided emulsion is provided that increases recording ability without increasing the need for additional media by footage, (including film stock,) and associated costs, or to capture secondary images (such as differently focused, exposed or slightly differently positioned capture lens images) for recording on opposite sides of a strip, or joined strips of colloid or other emulsion bearing (or embodying) materials.

  • the camera is selectively able to relay altered versions of the lens image (or other captured visual) to each separately exposed side of the emulsified material.
  • This feature is useful for recording on a single side relative to the normal film plane, for example whether the single side is exposed or film repositioned to allow for the reverse side to also be exposed.
  • the altered image versions may have different focusing priorities of the relayed lens image, may have different exposure times or f- stop (iris) settings during exposure, or may have offset lens captures, in case a plurality of lenses is used, of the scene being photographed.
  • Other possible imposed variations of differences selectively imposed on the captured visuals relative to each other are envisioned herein.
  • images recorded within film stock may provide information to affect final images of potentially much more image information, (affecting also quality and resolution,) while still not requiring additional media, (such as motion picture film stock,) in accomplishing the goals (individually or in tandem,) of additional provided overall images or increased image quality within final images derived from the film captures.
  • an entirely new film stock product is provided by teachings herein, as well as equipment used to expose, manage and screen the film stock.
  • This is possible, even though the gauge size and film configuration, whether recording on one or both sides of the film stock, can be unlike conventional film stock.
  • typical sprocket holes, familiar gauge sizes and other conventional aspects of film capture and screening may selectively not be involved in a new film "format" and imaging system, respective devices and methods as disclosed herein.

Intermittent motion of the film to subsequent frames for exposure might best occur after a "frame" has been exposed on each' side of the double sided film, in the double sided configuration, selectively.
  • a motion picture film camera preferably captures visuals through a single, initial capture lens.
  • the lens image may be selectively diverted and or divided (e.g., split), to allow for two separate relayings of all or part of the initial lens image.
  • a mirror which may be operable to move, relays the lens image during a period of time selectively to additional lens elements for focusing, particularly in case focusing has not already been accomplished prior to the mirror diversion of the captured lens image/light.

  • the offset is approximately 90 degrees, or perpendicular to the typical position of a film gate.
  • the mirror or other mirroring element(s) relays the captured lens image to a second gate during a predefined period of time.
  • This second capture gate may also be offset, relative to a typical film gate position, and may also perpendicular, for example, to a typical prior art film gate position.
  • the second capture gate is positioned directly opposite of the first offset gate.
  • the above-described embodiment preferably allows for mirrored or other image diversion elements to provide a full lens image to one gate and then the other for exposure of motion picture film, or other imaging means, (including, for example, charge coupled devices ("CCD") for electronic capture, or other electronic digitizing elements).
  • CCD charge coupled devices
  • all or a portion of the lens image e.g., if beam splitting is employed in lieu of full image diversion by mirrors or other elements
  • a CCD may receive intermittently all, or intermittently or continually a portion of the original lens image as well, to allow for video assist viewing, or related similar monitor (electronic) viewing of images being captured for film or other media recording by the present camera and invention.
  • electronic recording of the lens image may provide image information for additional digital image applications, related to the film captured images; including the option of allowing one of the capture media to provide key frame data at a selectably slower frame rate during capture than the other, whose image data may inform other aspects of final image data allocation and management.
  • a modified approach to using celluloid film may be employed by the teachings herein.
  • two strips of conventional film may be selectively joined or positioned.
  • the celluloid strips may be thin and separated by an opaque layer or piece celluloid or other material. This minimizes an amount of material and weight necessary for color negative film, and reduces the capture of a maximum number and film frames of a selected gauge size, such as 35mm.
  • One advantage of the embodiment that includes a mirrored diversion, as described above, is that a single strip of modified celluloid may capture twice as much overall image information by employing offset film gate(s) to allow for both sides of the celluloid to be exposed from visuals (light) captured through a single lens.
  • Another advantage is that, in the embodiment including two gates, which may be positioned in parallel or opposite to each other, is that a captured lens image may be selectively relayed as is for recording the unmodified lens image to each of the "gates" or respective sides of the celluloid having different emulsion.
  • the lens image may undergo selective secondary effects or modifications, such as additional optics providing different focusing priorities or other camera setting variations, for relaying the captured lens image multiple times.
  • a capture lens is positioned at a selected focal length, for example five feet from the camera plane focusing selection, might relay a visual (e.g., an image) which is relayed for a period of time to a focusing optic unit, preferably within the camera housing, for recording onto film (or other recording means) as a ""near focused" visual. Thereafter, the mirror or other relaying devices may relay the lens image to a different focusing optic set up, to allow for that period of time for relaying of the lens image to undergo optical variation by way of a different focusing priority, such as "infinity.” Alternatively, the same optics may be used that is selectively reset for another setting. This preferably allows for background focus, or background clarity in lieu of foreground clarity.
  • a single strip of celluloid might record twelve 35mm frames of film focused for "five feet" from the camera gate on one side of the film, while twelve frames of film (visuals) are recorded on the other emulsified side of the celluloid set with the infinity focusing priority.
  • 24 frames per second twelve or virtually any other number of visuals per second might be recorded in this way, on both sides of the media having emulsion.
  • the selected emulsion width (and thus overall emulsion area related to each visual captured) need not be the same on both sides of the stock; variably wide film gates and differing optic configurations may allow also for this option.
  • the frame rates between images recorded by one film gate and the other also need not be identical, depending on the objectives for the image versions captured on the respective sides of the strip of film stock relative to the final images for selectively display.
  • the example of multiple focus versions may be used for a special screening effect, such as three-dimensional effect or simply enhanced depth of field effects.
  • the dual-sided film might simple be utilized to increase the material efficiency of the film capture process.
  • the amount of film stock by foot can be reduced, for example, by half for the same amount of image information captured.
  • One benefit example of this result is a reduced weight of overall media necessary on a shoot, but that is only one example of many potential benefits of the increased efficiency.
  • offset multiple gates embodiments may be provided as two film gates exposing only one surface of typical motion picture film, as opposed to the embodiment described above including a double- sided emulsion celluloid.
  • two gates may record, for example, altered versions of the same lens image (such as differently focused) on a single strip of celluloid each gate recording only on every other frame of the film.
  • different focusing priorities may be provided by differently set focusing optic(s) that may allow for a single strip of film to provide media allowing for distinct post production options that are applicable and unique to the teachings herein.
  • a mirror and/or beam splitter to divert a lens image provides for different versions of a single lens image for film emulsion recording, or electronic recording including such options as digital CCD and the like, familiar to digital origination of visuals, such as with the CINE ALTA and other high definition digital cinema systems.
  • Different media working in tandem to capture such versions is another provided option and range of configurations possible within the present invention.
  • differently exposed or focused versions of the same lens image are recorded either simultaneously or selectively staggered over time.
  • An option of recording visuals on one or both sides of a single strip of specially prepared celluloid (such as provide with double-sided emulsion) is further provided by the selective lens image diversion and dual film gate, as described herein.
