ABSTRACT:
An improved bellows for use with a folding camera comprises a sheet of opaque resilient material, extending over an opening in the camera body. When the camera is folded, the bellows material is collapsed to a substantially flat plane, and when the camera is unfolded, the bellows material is expanded to define a light-tight, tent-like extension from the back of the camera.
In a preferred embodiment of the invention, the bellows material possesses a dimpled, or wrinkled microstructure such that the material is expandable in any direction by unfolding the microstructure.
