The Perfection 4990 Photo is a good value all-round device, which is considerably upgraded with SilverFast scan software.
Authentic colors: For calibrating your scanner, we recommend our patented and award-winning Auto IT8 Calibration using a calibration target from our own production in combination with SilverFast Ai Studio or Archive Suite.
Note on the Dual Lens System: For transparency mode, the Epson Perfection 4990 features two different focus levels. Select scan mode “Transparency”, if you want to use a filmholder. In this case, the focus of the scanner optics is precisely adjusted to the film holder. Use scan mode “Wide Transparency” only, if you want to place transparent originals directly on the flatbed.
