Abstract

A camera is provided with a color filter in the light path immediately in front of the film. Preferably, the camera is of the type having a film strip movable from a supply reel to a take-up reel, and the color filter is in the form of a strip of filters of different colors, carried by a pair of spaced reels mounted in the camera for movement of the filter strip in front of the film strip. An indicator is provided for indicating the color of the filter in position in the light path in the camera.

Claims

1. In combination,

(a) a camera comprising means defining a path for light therein, said camera having at the front thereof means for admitting light thereinto, a shutter, said camera having means for holding and advancing light sensitive photographic film transversely of the light path at the back thereof, and

(b) means for positioning one selected segment of a light color modifying means having a plurality of light color modifying segments in said light path at the back of the camera immediately in front of a portion of photographic film supported by said film holding means in position to be exposed upon actuation of said shutter, said positioning means positioning only said light color modifying means.

2. The combination of claim 1, said light modifying means comprising a color filter.

3. The combination of claim 1, said light modifying means comprising a strip of filters of different colors in serial array, each of approximately the same size as the photographic film capable of being exposed upon operation of said shutter, and filter supporting means enabling a selected filter to be brought into the light path.

4. The combination of claim 3, wherein said filter supporting means comprises a pair of spaced filter reels, and means for mounting said filter reels on said camera.

5. The combination of claim 4, said holding means comprising a pair of spaced film reels parallel to said filter reels.

6. The combination of claim 4, said holding means comprising a pair of spaced film reels perpendicular to said filter reels.

7. The combination of claim 1, said light color modifying means comprising a strip of different light color modifying means in serial array, and filter supporting means for moving said strip to place at least one of said different light color modifying means in position in front of film held by said film holding means.

8. The combination of claim 7, and means for indicating which of said different light color modifying means in said position.

9. The combination of claim 1, including means to prevent contact of said light color modifying means and said photographic film.

13. The combination of claim 9, including means to prevent contact of said light color modifier and said photographic film.

10. A camera and in combination therewith a support for a light modifier,

said camera comprising a body having a lens at the front thereof, a shutter, and means for holding photographic film at the back thereof,

said support comprising means for selectively positioning one selected segment of a light color modifier having a plurality of light color modifying segments at the back of said camera in front of and adjacent to film held by said holding means, said positioning means positioning only said light color modifier.

11. The combination of claim 10, and a light modifier comprising a strip of different light modifying elements, each of approximately the same size as a film exposable upon operation of said shutter, whereby said strip may be moved transversely of the light path between said shutter and film in said camera which is in position to be exposed upon operation of said shutter.

12. The combination of claim 11, and further comprising means for indicating the modifying element of said light modifier which is in said light path.

14. A camera apparatus comprising:

(a) a camera body having a lens at the front thereof, a shutter, and film holding means at the back thereof comprising a pair of spaced, parallel first reels for bringing successive portions of film into position to be exposed upon operation of said shutter,

(b) filter means comprising a strip of filters of different colors and each of approximately the same size as a said portion of film, and

(c) means for positioning said filter means with a selected filter in said camera body at the back thereof between said shutter and a portion of film in position to be exposed, and adjacent said portion of film, and for independently moving filter means positioned by said positioning means with respect to said film.

15. The camera apparatus of claim 14, and means for moving said filter means comprising a pair of second reels, said filter means connected to said second reels.

16. The camera apparatus of claim 15, and means for indicating the color of the selected filter in said position.

17. The camera apparatus of claim 15, wherein said filter means moving means comprises means for moving said filter transversely of film moved by said first mentioned reels.

18. The camera apparatus of claim 15, wherein said filter means moving means comprises means for moving said filter parallel to film moved by said first mentioned reels.

19. The camera apparatus of claim 14, including means to prevent contact of said filter means and said film.
