Cameras, methods, and systems with partial-shading encodements

A camera comprising:

• a body;
• a film holder having an exposure frame surrounding an exposure opening;
• a taking lens system mounted to said body, said taking lens system having an optical axis, said taking lens system transmitting a scene image through said exposure opening;
• a screener mounted to said body forward of said taking lens system, said screener being movable, relative to said exposure frame along said optical axis, between a primary position and at least one secondary position, said screener filtering said exposure frame differently in each of said secondary positions, said exposure frame being unshaded when said screener is in said primary position.

A camera comprising:

• a body;
• a film holder having an exposure frame surrounding an exposure opening;
• a taking lens system mounted to said body, said taking lens system having an optical axis, said taking lens system transmitting a scene image through said exposure opening;
• a shading screen rotatable, relative to said taking lens system, between a primary position and a plurality of secondary positions, said shading screen being offset from said exposure opening in said primary position, said shading screen shading a different portion of said exposure opening in each of said secondary positions.

A camera comprising:

• a body;
• a film holder having an exposure frame surrounding an exposure opening;
• a taking lens system mounted to said body, said taking lens system having an optical axis, said taking lens system transmitting a scene image through said exposure opening;
• a shading screen rotatable, relative to said taking lens system, between a primary position and a secondary position, said shading screen being offset from said margin opening in said primary position, said shading screen shading said exposure opening in said secondary positions, said shading screen having a border having a convex portion having a pair of opposed ends and an intermediate portion extending between said ends;
• a ring segment extending along said convex portion of said border, said ring segment being fixed to and rotatable with said mask;
• a screen drive engaging said ring segment, said screen drive being selectively actuable to rotate said ring segment and said shading screen mask between said positions.

A photography system comprising:

• a plurality of cameras, each said camera including:
• a body;
• a film holder having an exposure frame surrounding an exposure opening;
• a taking lens system mounted to said body, said taking lens system having an optical axis, said taking lens system transmitting a scene image through said exposure opening;
• a shading screen rotatable, relative to said exposure frame about a rotation axis, between a primary position and a secondary position, said shading screen being radially offset from said exposure frame, relative to both said axes, in said primary position, said shading screen partially shading said exposure frame in said secondary position;
• and
• a film unit removably disposed in said film holder, said film unit having a plurality of latent images, at least one of said latent images having an encodement pattern responsive to said shading;
• and
• a photofinishing unit including:
• a digitizer digitizing said filmstrips to provide a sequence of digital images from said archival images, and transmitting said electronic images;
• a digital fulfillment engine receiving said electronic images, said digital fulfillment engine including automatic digital processing of said digital images to determine the presence of said encodement pattern and to alter said light images having said encodement pattern in accordance with a modification preassigned to said encodement pattern.
