A camera for 4x5" plain film, no lens, just pinhole. After shot, a negative should by changed in a darkroom. Thus, it's one shot camera.
Setup for 10 minutes exposition. Luckily, windyless weather helps make the picture very sharp, as you can see on contact on Foma Speed paper, or on Foma emulsion painted on watter color paper.
