Change in Function
As of late, with digital scanning and image manipulation, non-photo blue fulfils its function in a different way. The artist can do his or her sketch and inking in the traditional method and scan the page. Most scanners will detect the light blue lines. However, shifting to greyscale and increasing the contrast and brightness will cause the blue to disappear. Another common approach involves replacing the blue channel with another channel – typically the red channel. The exact processes may differ depending on the scanner, settings and image-editing software, but the concept remains the same.

Famous quotes containing the words change and/or function:
“The most advanced nations are always those who navigate the most. The power which the sea requires in the sailor makes a man of him very fast, and the change of shores and population clears his head of much nonsense of his wigwam.”
—Ralph Waldo Emerson (1803–1882)
“Advocating the mere tolerance of difference between women is the grossest reformism. It is a total denial of the creative function of difference in our lives. Difference must be not merely tolerated, but seen as a fund of necessary polarities between which our creativity can spark like a dialectic.”
—Audre Lorde (1934–1992)
