You guys who take such a disciplined approach are wise. I just hacked away at it until I liked what I saw. But then it is just for me, and the archival asset is ultimately the film itself, which will be unceremoniously trashed after my demise. As someone mentioned, one of the beauties of Vuescan is the RAW function. It will store just the sensor's output, plus ICE cleaning for those films where it works. You can have Vuescan 'scan' the raw tiff file to process the rough color correction, leaving the fine tuning to Photoshop. It will save in DNG format, for processing in Lightroom, but I haven't figured that out sufficiently.
There is also a Fine setting (not just for Tom), which I found necessary to avoid banding effects on my LS-8000. That might be more a problem on negatives than on positives. It slows the scanning down, but I use 2000 dpi rather than 4000, which compensates somewhat. Haven't needed the max resolution for my little ink jet prints or Web displays.
When first learning about digital imaging, I got a lot of help from the tutorials published by Norman Koren. They may be a bit out of date now, but the info should still be valid. www.normankoren.com/#Tutorials
He is also a fine electronics engineer. I built his PAS preamp design last spring and it sounds terrific. www.normankoren.com/Audio/
There - I've brought the thread around to sound.
