G'Day Franc:
Thanks for the comment on Vuescan. I will look at it. I only have the one scanner (V750M Pro) so multiple unit flexibility is a moot point for now, and the 750 came with Silverfast 6 Ai at no extra cost. I have upgraded versions (for a few dollars) and have become used to it. It will scan to 48 bits if I wanted. For the moment, I will try to wring out all that Silverfast offers, but I will certainly take a closer look at Vuescan. Actually, the bigger problems which I have mainly overcome have been film carriers, keeping the media flat, keeping the dust off, and testing how far I need to take the scan passes etc. I have also tried the liquid mounting. The silverfast support forum is good, and I am really impressed by the rapid and personal response from the Silverfast support team. (My latest 'test' is scanning the media twice so that the second scan is for a 'heated' piece, just to see if there is a difference.)
G'Day Melton:
I use Firewire (with the anti-cockateil cable) feeding into an iMac Intel with lots of horsepower. Actually I scan directly to a G Drive so I can do other stuff while I am scanning. I really do not time the scans - I know it takes longer to set it up, than to scan it!! I have scanned positive and negative film in MF and 35, with good results. I'm sorry that I have no prior reference for 'speed' because this is my first digital darkroom venture. I have done multi pass high resolution scans making 300MB files, and these seem to take 6-8 minutes, but again, I have not timed it. I am usually off doing something else, and when I get back to it, it's done. I sometimes 'batch scan' for contact sheets, but more often concentrate on one piece.

BTW, for other forum members, the Cockatiel (Quarrion) is native to the Australian bush where I was born and raised. We had thousands of them in the fields, especially around wheat season. Of course, back then, no computers, so they HAD to eat wheat.
