I'm still mystified why I never had this problem before, but at least I'm up and running. I've also ordered a Kodachrome IT8 target slide, so as soon as that arrives, I'm going to try profiling the scanner with those analog gain settings. <<<<<<<<<<<<<
There's a discussion (ugly flame war, actually) going on about this on the usenet scanners list right now. The claim is that the Nikon light sources are monochromatic, so only measure the spectral responses of the dyes at three points. The further claim is that Kodachrome dyes have _average_ spectral responses that do the right thing, but that the details of the spectral response are such that there are strong valleys and peaks, and that those valleys and peaks vary from batch to batch. So the Nikon scanners can have wildly different responses to different batches of Kodachrome. Sounded sensible and possible, but I've never shot Kodachrome... David J.
