Studies on Colpophtos with Hand-made Devices in Early Periods

Ganse already published a Kolpofoto book, where he used a ring type speed light in front of 200 mm lens and Exacta Varex camera, we had neither Exsacta camera, nor a speed light even in common photography in Japan at the period, therefore we decided to use 250 W spot-light for the lighting, reducing its heat by inserting another spotlight lamp in the electric line of lighting lamp during the focusing preventing the patient to be burned by the spot-light heat, where the heat reducing lamp was removed by a foot switch immediately before taking a colpophoto. The camera was the Asahi-flex type I. A normal colpofoto is shown in . The system was revised 1960s using Hektor 135 mm F4.5 Leica lens extending the focus to 200 mm inserting an extension tube between the lens and camera making the lens aperture controllable.
