interpositive

n.A photograph, usually on film, with normal polarity that is created during a two-step process to duplicate negatives.

Notes

Interpositives are typically made using negative film; a negative of a negative produces a positive image. The interpositive is then used to make another negative. Interpositives are frequently used to make printing masters from original camera film or to reproduce still negatives that are deteriorating. Interpositives can be either color or monochrome.
