Struggling with the software for a day finally paid off as the secret to manual scanning was really in there and was fairly simple. With the negatives finally in the computer, I put together a new set of stereoscopic cards based on the shoot of Caligari participants/organizers. I lost about a third of the images due to problems advancing the film (leading to superimpositions) and to some light leaks (almost certainly caused by the lab using too much force when prying open the film canister). However, many are really good. Even some of the damaged ones are cool.
