What is the color depth of a scanned image?
Color depth is the number of shades (variations) of colors that can be obtained from an image. The more shades of color the scanner captures, the truer to the original any reproduction of the scanned image appears. When you scan an image, the pixel data (color depth) for each pixel is 24-bit (16 million color variations, 8-bit/color) for color, or 8-bit (256 shades) for grayscale images (black-and-white photos). The “Black-and-White” resolution setting records the data as either black or white in a 1 bit format. • Why are there different choices of scanning resolutions, and which one should I use to scan my images? Having choices for scanning resolution allows you to tailor scans to your needs. The resolution you choose depends on the output you choose. When you scan an image, the higher the scan resolution (or number of colors) the bigger the resultant image file is. To maintain good image quality from scanning to printing, and to maintain good file management, choose the resolution t
