ABSTRACT:
Digital image signal data is applied to a film recorder to produce a pseudo-negative using high gamma transparency film as the negative. The image signal data is modified before application to the film recorder to insert signal values, positive for positive transparency film and negative for negative transparency film, such that upon photographic processing of the transparency film, a negative image is produced with a positive orange mask effect. The pseudo-negative is then used to produce multiple positive print images conventional negative-working print paper.
