Thats what I have. An old cargo van with a berthiot 520mm f6.3 lens mounted in the door. Portraits can go as large as 4 to 1. Harman photo positive paper at iso 3 w with 2-7 second exposures.

I have that shoots that size built into a cargo van and I also use positive paper. Im just curious if the camera does the developing automatically while they wait. It takes an hour.
