Yet for a high speed material, the image formed is remarkably fine-grained. Scenes made on Superior-3 can be spliced readily with those taken on slower films. The contrast is variable within the usual working limits. Gamma for gamma, a 50% increase in developing time is required. This builds up the low-key detail without producing hardness. Superior-3 possesses the stability, uniformity and wide exposure latitude typical of all Du Pont Cine Negatives. When shooting with poor or inadequate lighting, its extra speed frequently spells the difference between good and mediocre results.
