Black-and-White Separations of Spacecraft Original Film (Preliminary)

摘要

During the space program a large amount of photography has been acquired in both color and black-and-white. Much of this photography is of great historical and/or scientific importance and should be preserved with the best techniques available.nUnfortunately, most present day color materials employ dyes which fade over extended periods of time. While proper storage conditions can greatly reduce the rate of fading, adequate archival stability over per-1ods of 50 to 100 years cannot be assured.
