The original photograph is not modified on disk. The game selects and projectively rectifies the carved tablet through UV coordinates, applies an estimated linear exposure factor of 0.72, and maps it to a shallow stepped sandstone frame. It uses the actual photographed tree-stump emblem, foliage and **1850** inscription. The source contains its original illumination and shadows; it is not a measured albedo or 3D relief scan. The photographic derivative is distributed under the same CC BY-SA 3.0 Norway license. Its rendered appearance may receive scene lighting, shadows and tone mapping. No endorsement by the photographer is implied.

The separate [entrance photograph](https://commons.wikimedia.org/wiki/File:Valbergt%C3%A5rnet_entrance.jpg), by Vogler, 17 November 2019, was inspected as geometry reference; its pixels are not bundled in the game.
