Scanning from ISIS
•
Chroma
—this option allows you to specify the amount of gray or
white used to dilute the colors in the scanned image. Move the slider
left or right to change the chroma level between 1 to 255. Low
saturation colors will appear washed out and highly saturated colors
will be pure and vivid.
JPEG Quality
—JPG files have different levels of compression. When
used with high compression, images are small enough in file size to email
or put on a web page. Low compression images maintains better image
quality when compared to the original, but the file sizes are higher.
Move the slider left or right to change the JPEG quality. Low quality
means that the compression level is high and some image quality will be
lost. High image quality means that the compression level is low and the
image quality is close to that of the original.
Drop Out
—this option tells the scanner and software to remove a specific
color from the image. This option is only available when scanning in
grayscale or black and white.
