Below you can see an experiment in preserving physical objects using photogrammetry. The technique involves taking dozens (or perhaps hundreds) of photos of an object from all different angles, and using software to stitch it together into a 3D model. The software can't infer the properties of the material in terms of how it reacts to light, so this has to be done using after the fact. In this case I've used Sketchfab to replicate the way that the bronze reflects the light.

The model you see is a recreation of a bust of Basil Liddell Hart, the founder of the military archive here at King's. This bust sits in the reading room. There are some flaws that can be edited out using 3D modelling software (the brass plaque is very smooth reflective and caused issues for the software; this could be flattened out in) and this is rather time consuming. But you can see the potential for preservation and providing remote access online.
