Abstract
Universal negative-holder frame for photographic enlargers, which is essentially characterized by two fundamental parts, one determined by a plate support and the other formed by a lid of the same nature articulated to the first, with a central opening appropriate to the passage of the image, lateral holes arranged in a position coincident with the band numbering of the standardized universal pass band and, finally, another perforation of smaller dimensions, able to allow, with the aid of a punctate reticle, the focus on the height of the frame relative to the sensitive surface.
