Digital archiving of cultural heritage has heretofore focused on capturing accurate color information via spectral imaging. In this paper, we review a means of capturing topographical information entitled Reflection Transformation Imaging. The paper discusses an experiment that attempts to merge these two techniques. Several paintings were imaged and color-accurate, interactive texture maps were generated. Experimental deficiencies are identified and suggestions are made for remediation. A new dual-imaging technique with improved capability is discussed. Our conclusion is that the simultaneous capture of high-accuracy spectral and textural information is entirely feasible.
