Kodak Ektapress 1600 (Gold II?) gave natural results with sodium vapor lighting, fluorescent illumination and also compact fluorescent lamps, as my recent scans of negatives from 1996 have shown. It is a pity that this film has been discontinued.
The new Fujicolor films give essentially the same results with such light sources as the earlier 4-layer types. But I assume that of the 4th-layer technology, initially integrated into Reala 100, the patent has expired now.
