Hi,
It can be done, but it is not easy. A few hints:
- Sensor and film needs to be aligned.
- The room where you shoot the dupes needs to be totally dark (if you can see the camera you are wasting details in the darks), so you need to eliminate all light leaks.
Best regards

I do it all the time with 6x6 film. The biggest trick is keeping the film flat and evenly lit.
I use a piece of PVC as a spacer, and shoot on top of a small light table. So far, excellent results. My only problem is color correction (going from color negatives, positives haven't been an issue at all). Because of the PVC, I don't need it to be dark in the room at all. I'm building up another rig, when I have free time, to do this on a stand without the PVC. Not sure if that will require darkened room or not.
