The Microtek V6USL USB/SCSI Scanner
  Introduction
  While Microtek 
    is far from a new 
    player in the imaging market, their presence in standard retail chains is 
    still growing. At least in the midwestern USA arena, Microtek's products are 
    too few and far between. Enter the bang-for-the-buck V6USL legal size scanner. 
    Will this feature packed model be enough to open the sales floodgates? Considering 
    the recently lowered to $149 list price, SCSI and USB capability and the LightLid 
    (for various negatives), this scanner screams, "Buy me and you'll get 
    a boatload of stuff!" While that may be true, I decided to compare the 
    V6USL to my aging but still current favorite Visioneer 
    7600USB.

  Description 
    & Specifications
  A few years 
    ago, scanners were either SCSI, parallel or USB. This is the first model tested 
    at TargetPC in which comparisons can be made across two interfaces.
  The SCSI 
    card included was a bit confusing. One sticker claims, "Adaptec AVA-2902" 
    while Win98SE found an "Adaptec AIC-7850." After browsing Adaptec's 
    site, I came to the conclusion that either model number was at least rated 
    as fast SCSI or 20MB/s transfer rate. Remember that USB revision 1.0 is rated 
    at 12Mb/s or 1.5MB/s.
  The LightLid 
    actually caught my attention first as I made a beeline to grab some negatives. 
    Easily fitting slides and old-style filmstrips, a 35mm still camera negative 
    required a bit of "futzing" before well aligned scanning could be 
    accomplished. 
  The included 
    software and accessories list is so extensive that I'll just point you to 
    Microtek's 
    site for those interested in all the details. Suffice it 
    to say that I was surprised when a limited version of Adobe PhotoShop 5.0 
    caught my eye during installation. Considering the low list and web prices, 
    the bevy of accessories is simply staggering and may prove to be irresistible 
    irregardless of the actual quality of the unit itself. Kudos to the marketing 
    people at Microtek for throwing all that stuff in the box and not forcing 
    the wary buyer to search all over town to locate badly needed "extra" 
    parts. 
  The 42-bit 
    color depth needs some verbiage however. I'm willing to concede that there 
    is quite a difference between 16-bit and 32-bit color as it is particularly 
    noticeable when playing Unreal Tournament. BUT, when viewing 16-bit scans 
    of human faces, there is not much improvement jumping to 24-bit "true" 
    color. After researching color depths, it appears that most human eyeballs 
    can distinguish 24-bit color, but only an excruciatingly small percentage 
    of those can see any appreciable difference between 24 and 32-bit color. I've 
    found no tests that confirm any detectable differences above 32-bit color. 
    What this means to the consumer is that you shouldn't be taken in by such 
    ideas that a 36 or 42-bit scanner will make any difference whatsoever. Here's 
    a table denoting the various color depths and exact number of colors.
  
     
      | 1-bit | 4-bit | 8-bit | 16-bit | 24-bit | 32-bit | 36-bit | 42-bit | 
     
      | B&W | 16 | 256 | 65,536 | 16.7M | 4.3B | 68.7B | 4398B | 
  
  B&W means black and 
    white (no color), the M denotes Million, and the B denotes Billion.
