Just scanned it in my Epson 4870, adjusted the exposure using the preview histogram, everything else was set to normal.
To be honest I wasn't sure what it would look like, my idea of a Kodachrome is lots of reds, so taking a scene with absolutely no red in it near midday seemed a bit of a gamble. The scan looks pretty close to colour of the slide, I'm not sure if it's a touch blue, but when I tried to tweak that the greens went horribly yellow and looked like a digisnap :0).
The only real post processessing was huge amounts of spotting, unfortunately I have to concur with other reports that Dwaynes can send back absolutely filthy slides (my previous roll was spottless though ).
Anyway, thanks for the comments, although it's difficult to take a duff shot in that part of the world ;0)
