Epson Perfection 4990 Pro TWAIN Driver
I got a crisper sharpness and smoothness of tones with no exaggerated graininess that I've not seen before from a flat-bed.
However, I must admit I still prefer Epson Perfection 4990 Pro TWAIN scan black and white silver film as a bit raw positive and then correct and invert in stages in Photoshop rather than using either scan drivers' software to invert and adjust the image values. If 35mm slide scanning produces good results with the Epson Perfection PRO, then medium format should really sing.
And now, with the 's greater dynamic range I was able to reproduce all of the tones precisely in a full-range shot of these falls on Mount Rainier. The detail and sharpness of the scan captured everything in the transparency, with accurately adjusted colors and good subject fidelity.
Black and white silver-based film negatives have always been an unusual scanning problem. The density range is relatively low so a lot of Epson Perfection 4990 Pro TWAIN is needed to spread the values across the available gamut, as the scan only fills a small part of the sensor's range. To control this process of both inverting from a negative and adjusting the image values to a linear progression, I still favor scanning at high-bit to a raw positive file and then making the inversion and corrections in Photoshop.
The result of this workflow from scans with the Epson Perfection PRO are just about the best image files I Epson Perfection 4990 Pro TWAIN produced. About the only complaint I had about the scanner was the time scans took at high resolution when Digital ICE is turned on. It's not the slowest scanning 35mm at dpi, but scanning film outputting a 15x19" image at dpi, which is something less than the scanner's maximum optical resolution, took some time.

I can only attribute this very slow processing to the fact Digital ICE is cleaning a larger film area. Evaluation And Recommendation I have been testing and reporting on Epson, and other flat-bed scanners, for some years now and cannot Epson Perfection 4990 Pro TWAIN coming to the conclusion that this new Epson Perfection 4990 Pro TWAIN Perfection PRO covers all the bases that distinguish multipurpose, professional-grade scanners in a smaller, lighter, consumer product at less than half the price of professional models.
The only significant difference is that professional scanners all have three-line CCD linear sensor arrays, and the Perfection has a six-line linear CCD array, with the inherent optical challenges that entails.
In all, however, the differences are becoming less apparent, and the yields excellent sharpness and image detail fidelity. Having used it for several months, I went for the Ai Studio upgrade and a target. The reason being that I always had trouble with i1 and in SilverFast the IT8 calibration works automatically.
I can definitely recommend both, scanner and software, unconditionally. It was like getting a whole new scanner for the price of the upgrade.

I have since upgraded to the Ai Studio version. While looking into upgrading with a new board or switch out completely to Epson Perfection 4990 Pro TWAIN New Window 7 Professional it became evident that I would have to make the big switch to a new replacement. I am heavily loaded with XP software so I was concerned about which software would have to be upgraded as well.
