Bloch Le Viallis

The Leon and Edmond Bloch brothers built only very original devices that must have had only limited success in their time, and therefore are now rarities highly sought by collectors...

 This stereoscopic camera is 6x13 cm format and is fitted with a guillotine shutter with five speeds obtained by spring tension, as well as with a time/instant exposure selector. There are three diaphragms on a leaf with holes.
 lenses are those of an theater eyeglass also used to view images by transparency, but also opaque views by installing an image support (absent. ..) on top of the unit.
