Abstract The Carolingian wall paintings on the upper floor in Chapel of Holy Cross were conserved from 2008 till 2016. In support these measures and investigations construction history, interior decoration, renders, whitewashes painting materials analysed. Towards end conservation work view future public display to a larger public, question was risen whether it would be possible make depictions more clearly visible by special photographic techniques, if techniques could also help transfer laboratory results few individual samples surface area. This led investigation selected areas using multispectral imaging (MSI). this paper, we report analysis scientific photography. It shows how two methods have supplemented supported each other during Cross, complemented observations relevant restoration conservation, enabled interpretation photography results. Hence, give an example that describes potential result-oriented interdisciplinary exchange.
