The new Coolscan IV ED incorporates a number of enhancements very similar to the Super Coolscan LS-4000 model, with a few exceptions (namely, 36-bit color depth as opposed to 42-bit, USB instead of FireWire, and no multi-sampled scanning). Here's a list of some of the key features of the Coolscan IV ED:
- Uninterpolated scanning resolution to 2900 dpi, interpolated to 4000 dpi
- USB interface, with drivers and software for Mac or Windows
- New Scanner Nikkor ED high-resolution lens, using extra-low dispersion glass
- 12-bit digitization
- Digital ICE scratch/dust removal technology
- Digital ROC for color restoration of old, faded negatives
- Digital GEM for grain reduction without loss of image detail
- Sophisticated color management system supports ICC profiling
