Retouching Losses were retouched to achieve an aesthetic balance of the whole object and to regain readability of the depicted scene. The retouching was executed in fine brush strokes to achieve full tonal integration with the original paint, but in a way that it is clearly distinguishable as an addition upon close inspection.
