A few weeks ago I gave a talk to the Cornwall Archaeological Society about 3D capture methods in archaeology, with examples of some of my recent work. It’s all work in progress, but here are some of the images shown during the lecture.
The stones were all chosen as case studies as they all contain details which can be difficult to see with the naked eye under normal lighting conditions. They include the Noti Noti stone in St Hilary, an inscribed stone and decorated crosses at Phillack, the Penzance Market Cross (left elevation) and the Cunaide Stone in Hayle.
I’ve always enjoyed digitising things – 3D scanning, 2D scanning, extracting scratchy audio from 1/4″ reel-to-reel tape, resurrecting a Betamax machine to transfer long-forgotten clips into modern archivable digital formals, turned oral history recordings on cassette into mp3, you name it. I have scanned and catalogued more photos than I can count.
Finally, I now have the space for my own digitisation studio, which I have begun to construct. It currently consists of a sturdy copy stand with LED lighting, Canon DSLR, Epson scanner, and a decent TEAC cassette deck. There is a trusty Mac sitting at the centre of it for control, capture and editing, as well as a Soundcraft mixing desk for audio input. Coming soon is a turntable (with 78rpm stylus) and an ex-studio VHS machine. On the wish list is a Betamax player.
The copy stand, as well as useful for capturing larger and more fragile items, also allows for me to have a Reflectance Transformation Imaging (RTI) rig set up for the surface capture of small artefacts. My recent FTTP (direct fibre-optic) internet connection allows for fast transfer of very large digital files quickly.
