THE IMPORTANCE OF ADEQUATE SCANNING RESOLUTION
Please review the sample images below.
The first photo is a faded 1914 print scanned as a color (RGB) image; the second is the same image converted to black-and-white, and whose overall tonal range, density, and contrast have been enhanced.
COMPARISON OF SCANNING RESOLUTIONS
Below are the details of the image above scanned at resolutions of 100, 300, 600, and 1200 dpi. The coarseness of the computer screen may lead us to conclude that there is not much of a difference in quality and sharpness between any of the four samples in each group. However, when these samples are enlarged or printed, the difference becomes very noticeable.
