    Some scanner/software combinations allow multiple line reading. Instead of doing a couple of scans of the entire negative and combining them, MLR takes multiple readings of each line during one pass of the scanner head and averages them. This can help eliminate noise, and it tends to have less registration issues than multi-pass scanning.

    By the way, these guys are great to deal with. How refreshing. After losing my Silverfast Ai disk for about a four or five year old Epson 4870 Pro scanner, they're allowing me to upgrade to their highest end software for a reasonable price. They would have replaced the needed Ai software for free. But, I opted to upgrade instead.

    What a class act.
    +1 same experience here. You don't always get customer service like this anymore.

    One of the irritating things about EpsonScan is that you don't really have direct control of the exposure as you would in say NikonScan. But I have noticed that the scan times vary with the selection made in the levels control. If your selection is made largely to the left side of the histogram, you'll get a longer exposure/slower scan. If the selection is encompassing a larger range, the scan times and presumably exposure are shorter. I would expect that you could trick EpsonScan into giving you a slow scan and a fast scan by manipulating the levels configuration. You'd have to blend it all together manually in photoshop, but this should work.
