Dima Tolkachov’s work “impossibility of unflattening the flattened” is an attempt to rebuild the completely destroyed city of Mariupol in an artistic act. With the help of the relief filter, Dima Tolkachov tries to reflatten houses, buildings and other urban objects in Photoshop on satellite images showing the completely destroyed city of Mariupol. This artificial transfer back into the third dimension deliberately fails twice here, since all the buildings as heaps of rubble and ruins have already lost their three-dimensionality in reality. In Tolkachov’s application, the filter even turns into its opposite. He did not translate these two-dimensional images of our world into a world full of depth and richness of detail, but puts a grey cloak of horror and concealment over them.
