<p>Multiple innovative digital techniques have been developed to study lithic artefacts (e.g. Olson <em>et al</em>, 2014; Bennet, 2014; Caricola <em>et al</em>, 2018; Grosman <em>et al</em>, 2022 & 2011; García-Medrano et al 2023). Based on its flexibility and relative affordability, multi-image photogrammetry has become an increasingly useful analytical tool within archaeology (Magnani <em>et al, </em>2020) with Close-Range Photogrammetry being used for lithic analysis (e.g. Caricola et al, 2018; Porter et al, 2016 & 2019; Collins et al, 2019; Bennet, 2021; Timbrell et al, 2022).</p>
<p>The imaging approach entails capturing a set of overlapping digital photographs of the subject which are processed with specialised software in order to produce 3D geometry. </p>
