| Research Abstract |
Based on an assumption that the black and white contrasts of monochrome photographs are dependent on (i) the characteristic of photosensitive materials, (ii) illumination spectra of light source, it was found that taking monochrome photographs of coloring samples under the same conditions as the reference photographs and comparing the contrasts of both can lead to the decision of original coloring. Using this method, decision of the original coloring of a portrait of a king of Ryukyu Kingdom Sho-Iku (1813-1847), which has been reported to have been lost during the World War II, was carried out.
