| dc.description.abstract | Colour is considered a representative characteristic of material cultural heritage pieces, especially when documenting them. Especially under digitalization processes, colour needs to be handled and preserved with care, given that digital tools may introduce uncontrolled variations in its representation, if not irreversibly lose it to certain degrees. This work aims to present an empirical workflow in order to successfully respect colour integrity when performing photogrammetry as a cultural heritage documentation asset. An experimental battery based on different combinations of acquisition conditions, RGB debayering, calibration and photogrammetry is presented, and based on the most successful parameters, conclusions are drawn for building guidelines for the optimum performance. The fact that control must be held over all processes to avoid undesired losses of information has been regarded as the highest priority, with the sole exception of the unpredictable colour blending operations during the proper photogrammetry. This paper ultimately demonstrates that preservation of colour information can be achieved on an excellent degree, and that having control over the factors of acquisition and colour digitalization parameters contributes to its success. | en_US |
