Retouching and supplementations – walking a thin line between completion and misrepresentation

Conservation also means the restoration or at least the increase of the recognisability of the image's original message. In this context, however, blemishes often impair one's perception. Yet the line between well-founded reconstruction and made-up misrepresentation is often very thin.

Contemporary supplementations should never interfere with the original context or look as if these were pushed to the foreground. They must subordinate to the original – and simultaneously remain recognisable and reversible for the expert.

Retouchings of blemishes are realised with suitable glass (according to the concept, in terms of colour, thickness, structure) and reconstructed with glass paints to be annealed in the corresponding painting technique.
