gives the best image quality, it also takes up the most storage space when the image is finally saved to disk.
◗256 Colors —Saves the scanned object as an 8-bit color image. Although an image scanned with this option requires only a quarter of the file size it would if it were scanned with the Color Photo option, only 256 colors can be represented. This option is best for a color image that doesn’t have as many tones as a color photograph would, such as a color drawing.
◗Black & White Photo —Saves the scanned original as an 8-bit grayscale image (256 shades).
◗Black & White Halftone —Saves the scanned object as a 1-bit halftone image.
A halftone image is composed of small black and white dots that give the image the appearance of having shades of gray. Most black and white images in a newspaper or magazine are printed as halftones.
