Leica Leitz Wetzlar ELDIA Film Negative / Slides Copier / Printer - Mint in Box!

A simple film copying device from Ernst Leitz, the makers of the Leica camera.

What is it used for?
Imagine you have some 35mm b&w negatives and you want to project them for an audience. Also imagine that this is decades before computers, scanners and digital projectors became common utilities. In this world - queue the Film Copier that can turn your favorite Tri-X photos into bright slide projections.

How does it work?
A roll of undeveloped film is loaded into the film copier and then a roll of developed negatives is fed through the copier and exposed frame by frame (a simple lamp will do) creating 1:1 contact prints onto the positive roll. As simple as that. It is also possible to feed a strip (or single frame) or photographic paper through the copier to create a strip of paper contact prints.
