What is an Ermano camera?

In the 1920s, news photographers and other professional handheld camera photographers mostly used a camera called "Ermanox". This medium-format camera was produced by the Hermann Factory in Dresden, Germany in 1924. The film size is 6.5 × 9 cm. It was equipped with an f/1.8 lens, the largest aperture in the world at the time. Using this camera, you could quickly capture photos using indoor ambient light.
