A method is chosen by the question. Each technique below makes a different kind of evidence visible, and most of my projects combine several of them with the work of archaeologists, historians and conservators.
The geometry of a place or an object, measurable and open to study from any side.
Surface relief too faint for the eye: incisions, tool marks, worn inscriptions.
Traces of pigment that the eye no longer separates from the wall.
A whole wall and a single mark in the same image.
A place as it is seen from where someone stood.
What it is like to be inside a record of a place.
A site opened to the public as a guided route.
Context and method
These methods are rarely used alone. A typical project starts with photogrammetry for geometry, adds RTI or DStretch where a surface carries faint marks, and uses gigapixel or 360 imaging so that a viewer can move between a whole site and a single mark. Each step produces a computational surrogate of the place, and I treat every one as an interpretation: the processing choices are documented together with the result, so that other researchers can judge what an image shows and what it leaves out.
