Photogrammetry can be used to reconstruct 3-dimensional models from a series of interrelated 2-dimensional images. The technique utilizes projective geometry to generate a point cloud within a 3D coordinate system based on relative points of reference across the image set. Single points of view coalesce into a multi-faceted copy, one in which new optical perspectives are made available that are inaccessible to the single images alone. Rather than an isolated render, a new element is synthesized, existing in relation to, yet set apart from its individual constituents: an emergent phenomenon, much like a body, or a family.

This type of copy has a poetic relative in the twin, and the constitution of one is reflected in the surface of the other. In Christian mythology Jacob duplicitously steals his twin Esau’s birthright and blessing; the astrological Gemini is inconsistent and multiple, and hard to trust. Even the etymology of the word shows it to be polymorphous: "to twin" has been historically used to affect a bringing together; but also to fragment, making two from one.

If a copy is to be like something, then it can only be like itself: something from which the original may sometimes be inferred, sometimes extracted; yet something in which the original is only a point of reference, seen through a lens.
