The Beseler Negatrans is special negative carrier designed to save time and minimize handling of the film when printing multiple images from the same roll of film. The negative carrier does not have to be removed from the enlarger to move the film to the next frame. Instead, the film strip is inserted in the carrier and the film moved from frame to frame by simply turning a thumbwheel. Nothing touches the image area, minimizing fingerprints and scratching. The 35mm Negatrans prints standard 35mm negatives, plus has a built-in mask for 1/2-frame 35mm. A small built-in window can be opened to project the frame numbers on the baseboard when desired. The #8081 35mm Negatrans is compatible with all Beseler 4x5, 23C, 67 and Printmaker series enlargers.
