Felix Horn: Digital imaging, a tool of preventive conservation Back
Language: Original   -   Translation
Abstract: The numerous reversals of restorations underline the importance of minimal invasive methods and preventive conservation. In this context, digital imaging gains significance as it permits providing a virtual restoration respectively virtual reconstruction of a former state. Three examples are used to demonstrate possible measures and the difficulties encountered. Each task requires its own digital approach including corresponding software.
In the case of some fragments of a Roman wall, the question is how to exhibit them in the future. The old inexpert adhesive would have to be removed. In order to rejoin the fragments, they would have had to be joined in a mortar bed. Digital imaging allowed exact and reversible joining of the fragments: it permitted virtual completion and retouching without actually touching the fragments themselves.
A second example is an extremely fragmentary Ptolemaic cult cloth. The loss of shape and the fragility of the painted textile made restoration impossible. It was obvious to try to obtain an impression of the original appearance of the cult cloth on the monitor.
A third example is a large tapestry from Brussels showing all the damage typical for these picture carpets: hanging had not only led to a loss of shape due to the force of gravity, but also to fading on the front side. Digital imaging permitted gaining an impression of the colorful front that once distinguished it. Scanning in the unfaded colors of the rear side and transferring these color values onto the front side yielded a virtual image of the original coloring.
