Why not set the longest so you always catch the full amount in one scan? Isn't the unit calibrated by the manufacturer to catch that anyway? (the dmax). Just scan at the maximum potential, dmax, of the scanner and you'll get the shadows first scan. Why lower it to create extra scans?

CCD (like CMOS) sensors have lower dynamic range than PMTs in drums, one way to overcome that is Multi-Exposure, V850 with right software (SF SE plus, for example) can make 2 scans with different exposures and then both results are combined to get a larger range.
Other expensive scanners (I guess) may make the 2 exposures before the carriage advances to next row.
If you have a very dense or a very thin film, without much dynamic range in it, then you can save a pass by adjusting the right exposure, and still having best results possible.
IMHO adjusting exposure is not always useful, but it can be sometimes.
V850 is not Pro gear, perhaps it's semi Pro, and it has some limitations, but in the hands of an skilled user it can deliver amazing results that are far beyond we can guess from its cost, in special with LF formats.

It should be like this.
With epson and sf you have Continuous Auto Exposure, Recommended Value, and Auto Exposure Level options, so the auto behaviour can be modified away from the "recomended" setting, this works fine, but it's great that Vuescan has that direct adjustment, I like it.
Here is an example of a scan from the V850 at 4000 dpi and AA off. 5x4 Extar 100

How do I get larger images to post to the thread? The limitations don't allow for a very big image, dimension wise that is. I see some fairly big images in the thread.
