Speed counts, if less so than image quality. Time the scanner, keeping in mind that its speed will be affected by the performance of the PC to which it is connected. Any scanner worth considering will come with photo-manipulation software. The control software, or driver, that comes with the scanner is as critical as the scanner itself. It sets and adjusts the color automatically but allows you to override the settings and make your own choices.
Drivers can be complex and intimidating.
There's no point in buying a scanner if using it is so aggravating that it gathers dust. Inc. All rights reserved.
