A folding bellows is provided for use in a folding camera that is movable between erected and storage positions and includes a base section housing having a film plane therein, a pivoting objective lens housing near one end of the film plane, and a pivoting mirror near the opposite end of the film plane for reflecting light from the lens onto the film plane to expose a film unit thereat. The bellows includes a bottom section attached to the base section, a forward wall attached to the lens housing, a rear wall that overlies the erected mirror and has a lower section attached to the mirror and an upper section that is not attached to the mirror, and a extensible top wall. When the camera is erected, the bellows assumes an erected position wherein it forms part of an ambient light excluding exposure chamber for light shielding the camera's exposure optical path. When the camera is folded, the upper section of bellows rear wall pivots back over the lower section and the top wall is extended to overlie the upper section so that the bellows assumes a flat storage configuration.
