Dark papyri are often difficult to decipher because of the lack of contrast between writing and background. Good results are obtained in the far-red near-infrared spectral band. The use of modern CCD TV cameras and films for aerial photography in this band is described as a flexible tool for inspection and fine-grain photographic recording, respectively. A dark papyrus has been examined. Images taken in this spectral band are shown to demonstrate the improvement in legibility.
