Jules Richard was a French industrialist who had a great influence on the popularity of stereo photography at the beginning of the 20th century. He introduced two new image formats and launched a wide range of stereo cameras, stereoscopes and accessories in various price ranges.
The Stéréo-Panoramique Leroy was an innovative camera developed by Lucien Leroy. The camera could produce both stereo photos and panoramic photos on 6x13cm glass plate negatives.
My latest acquisition is a wooden 6x9 field camera from the 1890s. It's a stereo camera with two lenses from Balbreck ainé.
The Glyphoscope was a stereo camera using glass plates, developed by the famous manufacturer Jules Richard from Paris. It was a compact, simple and affordable camera that could also serve as a stereoscope.
