Graphic documentation is essentially a document, mapping the state of conservation of the walls. In this case it helped give a clearer view of the areas that needed to be uncovered and treated, since originally these walls were gilded / painted. Unfortunately this mural art had been coated and whitewashed several times in past years. Thus this campaign was followed by trails for the uncovering of mural decorations.
