The colour >rendition of Kodachrome is amongst the best(?) I have seen - but compare it >to Velvia and it looks flat, Some time ago there was an interesting test report in Pop Photo. They're sometimes a good source of technical background. Anyway, although I don't have the article in front of me, it said that the sensitivity of the dye layers in color film could be either narrow, with resect to the color spectrum, or broader. The narrower sensitivity resulted in less overlap between layers and produced brighter color. This would be the Velvia look. A broader sensitivity of each color layer to a wider range of color frequencies resulted in more muted color, but also allowed greater discrimination of fine hue differences. Kodachrome would be in this category. I haven't seen anything written on this since, but it would be interesting to know if technology has changed anything or if it's simply an either/or thing.
