Shell Photogrammetry Sub-Millimeter Test

This shell measures 27mm long and was processed into the 3D model below using macro photography and photogrammetry. This loop fades between true colour combined with artificial light, then grey topography and back again.



I was careful to light the surface in such a way that the shadow of the camera would be clear for all of the positions needed. The shell was supported with a pin and bluetac, visible at the base. This test was designed to explore the potential of these techniques for recording archaeological artifacts.
