STORM TRACK: January 31, 1978 (Volume 1 Issue 2)
For slide projecting I suggest using duplicates, since all color dyes fade in time and repeated projection hastens this process. According to the January issue of Modern Photography, Kodachrome dyes are longest lasting; slides are more durable than negatives; Cibachrome prints are -likewise- recommended; and cool (up to 70 deg F), dry (RH 15-40%) and dark storage is best.
