30VISIONEER STROBE XP 450 SCANNER INSTALLATION GUIDE
■8-BitGray—scans the image using up to 256 true shades of gray. Use this setting to scan black and white photographs and other higher quality black and white images. You can also scan a color photo with this setting to turn its colors into gray shades. The file size is about one third the size of a color scan.
■24-BitColor—scans the image in full color. Use this setting to scan color photographs and other color images. The file size is the largest of the image type options.
■Enhanced bit-depths—If you are using an imaging application other than PaperPort, the image type drop-down list will include 16-Bit Grayscale and 48-Bit Color. These image types are only available if the imaging application supports them. You will receive an error message if the application does not support the selected enhanced bit-depth.
Note: You can see the file size at the bottom of the Scan Manager.
RESOLUTION
Resolution determines the amount of detail you can see in the scanned image. The resolution setting for a scan is in dots-per-inch (dpi). The higher the resolution, the finer the details, however, higher dpi settings also take longer to scan and produce larger files sizes. Usually the higher resolution settings are used for precision work, such as photographs or fine artwork.
■Click the Resolution drop-down list and select a resolution.
The resolution settings on your Strobe XP 450 scanner range from 100 dpi to 2400 dpi.
BRIGHTNESS AND CONTRAST
Sometimes an item is scanned with the brightness and contrast set too light or too dark. For example, a note written with a light pencil may need to be scanned darker to improve legibility.
