Photographer's Note

The empty attic Labruguière these old glories of their best profile photographs appear in the spring sun. These are folding. Technically they're workshop rooms, the bellows folding (folding) connects the film plan to all shutter / lens. First advantage, the flexible connection allows easier implementation at the point in playing on the distance between the film plane and the lens. Another advantage is that the bellows can be completely folded and to be housed, and the shutter with the lens in the housing body. Black chamber of the apparatus being thus closed, the space saving is significant and the folded device can fit in a pocket. This type of device will undergo continuous improvement until the late 1940s. D'clever mechanisms jamb allow all elements of the camera (shutter, lens, bellows, prism viewfinder) to withdraw or to move into position automatically. If the first foldings using a variety of formats (4.5 x 6 cm, 6.5 x 11 cm, ...) the appearance of size 620 and 120 into widespread format 6 x 9 cm for such devices. This format allowed a negative print on photographic paper without magnification by direct contact.
