Abstract
Camera with adjustable viewfinder mask having differently dimensioned openings for pseudo-photography, has light pipes to provide binary coding of film frames corresponding to mask positions.
Claims6
In a photographic camera for making pseudo photographs on film exposure areas upon opening of camera shutter means, said camera including adjustable view finder means for selecting from a range of pseudo fields of view for exposures, the combination comprising:
- means for directing ambient light to a selected fiducial area of the film,
- means under the control of said viewfinder means for controlling ambient light passage by said directing means to provide a predetermined coded pattern of exposure of said fiducial area, and
- means blocking ambient light passage to said directing means except when the camera shutter is open.
In a photographic camera for making pseudo photographs on film exposure areas upon opening of camera shutter means, said camera including adjustable viewfinder means for selecting from a plurality of pseudo fields of view for exposures, the combination comprising:
- light piping means for conveying ambient light to fiducial areas of the film.
- a movable masking element comprising part of said adjustable viewfinder means, said masking element having a plurality of differently dimensioned masking openings and being movable to bring selected openings into alignment with the viewfinder, said masking element further having an extension which has portions of different dimensions and positioned in the camera to provide a varying degree of blocking of said light piping means, depending upon the particular masking opening aligned with the viewfinder, and
- an element forming part of said shutter means and positioned to block passage of ambient light to said fiducial area except when said shutter means is open.
