I'm looking for a low resolution (no more than 600 dpi native) flatbed scanner with more than 8 bits per channel sent to the computer, and that has a transparency head for at least 4" x 5", preferably larger. The reason I want low resolution is that the final resolution of the scanned transparencies is low, and I do not want to deal with the moire patterns I get with decimation of high res scans (which is what most scanner software does when you want a scan at lower-than-native resolution), nor do I want to deal with huge files and then use bicubic interpolation in PhotoShop. I do need high bit depth as these are very old B&W negatives, many of which were not properly exposed (ranging from extremely thin to incredibly dense). Quite often *all* the info is in the shadows! This is a job to be done at a remote site where it is much more appropriate to use a laptop than a larger computer, but that means limited disk space, limited memory, and limited speed of both the CPU and disk. In such a scenario smaller files are better. Thank you for your suggestions, --Dana
