Before discussing the distinguishing functional features of the Perfection 4990, I’d like to offer you a table that lists all the basic technical characteristics of the model. As usual, EPSON offers quite comprehensive information about its product.
We can’t overlook the fact that the optical density parameter has improved to 4.0Dmax. It means the scanner will now be better at digitizing negatives. It will most probably handle successfully “dark” film and even X-ray images. By the way, you now get additional film holders with the scanner.
Of course, high resolutions are necessary for digitizing transparent originals well. The EPSON Perfection 4990, like the ex-top model, sports an optical resolution of 4800dpi and a mechanical resolution of 9600dpi.
If you compare the characteristics of the new and previous top models, you will find that the new scanner is more reliable. The machine is now expected to last through 100,000 duty cycles against the previous model’s 30,000. In order to bring the scanner home safely, it is handed to you in its package which contains a lot of useful things.
