BPM Bellows Camera and lens Mounts

Each mount was hand engraved with the camera or lens fitting, as seen here with the Pentax K version. The mounts had no form of mechanical or electrical coupling so the system is totally manual.

BPM Reprotran

Accessory for BPM bellows system that is used for copying film. It attaches to the rails of the bellows system and the transparency to be copied is held flat on to the diffusing screen by the two spring clips. These allow the slide or film to be placed in most positions for reproduction and can also be used to copy from a portion of medium format transparency film.

Once the transparency is in place and roughly focused using the bellows, the distance of the screen can be finely tuned for focus using the extended screw bolt.
