How Tom can help your project

3D Scanning and Digital Surface Enhancement

This is a globally rare specialism. Using high-resolution 3D data and a suite of digital surface filtering techniques — ambient occlusion, depth mapping, sky visibility, positive openness and more — Tom can reveal carved details invisible to the naked eye. He works with rock art teams, epigraphers, medievalists, classicists, and museum curators on prehistoric petroglyphs, early medieval inscribed stones, decorated monuments, and small artefacts. He can work with your existing 3D data or capture new data remotely or on-site.

Clients include Historic Environment Scotland, Historic England, and Cornwall Archaeological Unit with research as part of teams published in the Cambridge Archaeological Journal, Time & Mind, British Archaeology and many more.

Audio Restoration

Wax cylinder recordings, fragile acetate discs, degraded magnetic tape, dictation wire — if it’s a historic recording that’s hard to hear, Tom can help. He applies specialist noise reduction, click and crackle removal, and audio enhancement to make voices, music, and spoken word intelligible again. This service is used by archives, oral history projects, museums, and private collectors. Remote working means files can be sent from anywhere in the world.
