Abstract
A painting is not a solely a static depiction. The painting as an artefact is in fact a three-dimensional landscape of paint, with varying appearance properties across its surface, including color, topography, gloss and translucency variations. This effect can be intentional – for instance using paint to create a 3D effect – or the consequence of drying, hardening, or degradation. Aging, environmental influences, handling, but also conservation treatments have and will continue to influence the appearance of a painting. Currently, the documentation of a painting’s complete appearance is generally limited to archival photography, representing it as a 2D image. A more extensive documentation of appearance – and changes over time – is generally not captured.
