So I've been playing around with Kodachrome and my Nikon V. I've learned a couple things. First, its a pain in the butt to get details out of the shadows. I'm just not getting out of my scans what I see when I hold the slide up to the light.

I tried Nikon Scan and Vuescan, and they both seem decent. I think I like Vuescan more for Kodachrome and B&W but Nikonscan more for C41. Anyway, I (think) I'm getting better scans by scanning 1-3 times in Vuescan. If its a slide with little in the way of shadows, I can get by with one scan with the analogue gains set just right. If its a tougher slide, I've found that I scan it with the gains set to 1, then 5, and maybe 10. I then open up all these images in Photoshop and merge to and HDR, setting each scan either 1 or 1.5 EV apart. Then I convert to 16 bit, with the exposure set low enough that I don't blow out any highlights and the gamma set high enough so I have a nice low contrast scan. Once in 16 bit, you can set levels/curves to give you the contrast you want and adjust the color. It seems to be working ok. Thought I'd share.

I'll post a pic or two shortly.
 
Same here. vuescan does a better job for K64 on the V than nikonscan. The situation reverses for the 9000, but that's another story.
I've been getting good results by simply using the full 14-bit scan of the V and then adjusting the curves on vuescan to recover shades. Extreme cases might require multi-scan, which vuescan will do but not nikonscan. I then save in 16-bit tiff for further post-processing with Neat Image. The output of that is 8bit as I'm done heavily processing then. Seems to work better for me this way and saves messing around with editing 16-bit in memory size terms.
