8-BIT GRAY

A single-channel image consists of at least 256 shades of gray. An 8- bit scanner produces a greyscale image with 1024 shades of gray between pure black and pure white. Choose this option if you are scanning black and white photographs.

With 8 bits of color information per pixel, the file size of an image is eight times larger than a black and white image and 1/3 the size of a 24-Bit Color image.

24-BIT COLOR

A 24-Bit Color image consists of three 8-bit color channels. The red, green, and blue channels are mixed together to create a combination of one billion colors which give a more true-to-life quality to the image. Choose 24-Bit Color if you are scanning color photos.
