The DiMAGE Scan Dual III can identify over 65, 000 gradations in each of its three color channels (red, green, and blue). Called 16-bit A/D conversion, this process delivers digital images with smooth colors gradations, and captures shadow area details that get missed with conventional 12-bit input. Precise color reproduction is further supported by the scanner's wide 4.8 dynamic range. Considering the size of your film source, high resolution is an absolute must. And at 2, 820dpi optical resolution, the DiMAGE Scan Dual III gives you more than enough detail for creating web graphics or electronic photo albums. You also get impressive results for more intensive applications, such as making large-size printouts.Random noise may sometimes occur in the dark areas of an image. To help minimize this, you can set the DiMAGE Scan DuaL III to sample your film 2, 4, 8 times, or OFF. This enables it to obtain more information from the film source, resulting in clearer scans. Minolta's innovative focusing system offers rapid autofocus calibration, and uses a propriety method to achieve high focus accuracy with any type of film image. You'll get sharp scans even from low-contrast images. For added flexibility, you can switch to Point AF or use manual focus to make fine adjustments in +/-200 steps. Negative film differs from positive film in several subtle ways, so a different process is needed to ensure high image quality. The advanced conversion process of the DiMAGE Scan Dual III makes sure that your negatives are scanned with optimum fidelity to the original film images. To deal with the problem of inconsistent colors, the scanner comes equipped with an effective color matching system that maintains uniform color among different monitors, operating systems, and image editing software. This will make it easier for you to manage colors for electronic or print applications.
