Thanks for the interesting comments re film scanners vs the DSLR copy approach, which pretty much echo my own thoughts. I'm another member of the Coolscan V and VueScan gang, which I'm reasonably happy with. The Coolscan was a pre-owned purchase from Ffordes and, as usual with their s/h stuff, was rather better than described. Think I was lucky to get it at the time (about 4 years ago), as they don't appear on their site very often. It replaced a Canon FS4000US, which was OK but starting to make worrying noises in the film carrier transport department - not uncommon, apparently.
My only gripe with VueScan is that I keep finding tweaks that make the results even better, so that previous scans (hundreds) really ought to be done again to match that standard.
However, encouraged by Rob (I think it was), I dusted off the Nikon scan software (plus 64-bit patch), mainly to remind myself why I didn't like it, and came away very impressed - it certainly breathed new life into old Kodachromes so I must try it on some old Fuji slides (my more usual diet, back in the day) to see if it's similarly successful. I think my main grumble with it previously was that it was a bit clunky when scanning strips of negatives (or trannies), which Vuescan does effortlessly - but probably I was too lazy to find out how to do it properly. I'm also having a slight tussle making the output pane match the preview one - but that's maybe just a matter of tweaking the curves.
Anyway here are three from a vintage meeting at Donington in May 1979 - straight from the scanner, with no Photoshoppery (mainly to eradicate any blobs left by ICE - I had that set to Normal, as I believe it can affect definition if you get too ambitious with it). For sad people like me, the support vehicles in the Paddock are almost as interesting as the vintage machinery ...
