Bellows camera
A bellows camera is a type of camera designed in the era of the daguerreotype  ( years 1840-1850 ) and, with many improvements, still in use today. It comprises a flexible bellows that forms a light-tight seal between two adjustable frames, the frontal one with the lens, and the other on the back of the camera with the ground-glass screen that will be replaced by the photographic film holder to take de photo.
