Tri-Color-Camera Other Rare small magazine hand stereoscopeThe Tri Color camera was introduced in 1925 by Jos Pe in Hamburg, Germany. The all metal camera produced three black and white negatives simultaneously, each recording one of the three additive primary colors. Two internal beam splitters directed the image to three separate plate holders, each one with either blue, green or red filter. It had an uncommon focusing system by moving all three plates back and forth simultaneously. 4. 5x6cm, Steinheil
