Fig 5.

Hyperspectral images of the Ricardus Dialogue: (a) shows an image from the green portion of the spectrum, chosen for the good visibility of the text; (b) is a false color image made to enhance the contrast; (c) shows a magnified portion of the text for comparison. Note the blurriness of the letterforms in comparison to figure 4c as well as the greater preponderance of visual noise in the image.
