Three Dimensional Calotypes taken with my 1890s London Stereoscopic camera. The camera is not without issues the worst being a balsamed lens making one slower than the other, that can almost be overcome during development. It makes focusing difficult too. The Septum was to long and presumably not original and the tripod thread had a metric 7mm thread probably for export. A new lens has been promised by he seller I have glued the septum to the right length and a bolt has been sourced cut to size and a tripod mounting plate adapted , But it works ! It is just a bit more challenging .
