The second floor, where the servicing and the film development happen.
A repair bench with a shutter tester, collimator and the jigs for the mounts we see most. A wet lab running C-41 at controlled temperature and black and white by hand. A Noritsu HS-1800 for scanning. And a darkroom with two Durst enlargers.
It is one room doing several jobs, which is the point — the person who develops your film is the person who scans it.
If you want to see your camera opened, or watch a roll come off the reel, ask at the counter. We are not precious about it. It is easier to trust a bench you have stood next to.
