An Automated Blowup Printer

The printed results of making 35mm blowup negatives from film shot in 16mm have improved dramatically over the past 25 years. This improvement can be attributed to numerous factors: improved lenses, cameras, 16mm film stocks and blowup negatives; new ways of eliminating the effects of scratches and abrasions on the original; use of new high-quality aspherical blowup lenses; more effective exposure-control techniques; and the super-16 format. Taking advantage of the first factors is still the responsibility of the filmmaker, but the others are effectively used in a new, fully automated, additive, blowup optical printer which is described. The advantage of the printer is that a complete feature dupe can be made in just a few days compared with the weeks to months necessary for nonautomated systems.
