Precise capture of colors in cultural heritage digitization

A workflow for the color reproduction of digital still images for the purpose of cultural heritage digitization is presented. An analysis was performed to determine the effect of RAW to TIFF transformation; RGB to CIE L*a*b* transformation; white balancing; use of standard color spaces: sRGB, AdobeRGB (1998), ProPhoto RGB, eciRGBv2; custom DCP, and ICC profiles assigning. For the analysis, Color Checker Classic and Digital Color Checker SG targets were used. The precision of the color reproduction was checked against FADGI and Metamorfoze standards. We demonstrate that to obtain high color fidelity reproduction, white balancing and a custom ICC profile are necessary, while DCP profiling could be omitted. © 2016 Wiley Periodicals, Inc.
