Abstract

As a result of the digital revolution, many journal articles have been written on the technical aspects of digitization. One of the most documented facts is that increased scanning resolution means greater legibility of the text and fine details of the digital file. However, little has been written about the fact that increasing the resolution also results in better color reproduction, and it is this issue that this paper will address. While the differences in color reproduction between high resolution scans and lower resolution scans are subtle, they can be quantified and illustrated graphically using the histogram feature of Adobe Photoshop (an image processing software package). This article begins by reviewing the principles of scanning after which several color images, both color and black and white, scanned at increasing resolutions, will be presented to support the author's thesis.
