Photogrammetry is the process of collecting a series of still images or videos of an object, such as a shipwreck, and then loading those images into software that can triangulate the photographed points to create a 3D model. Plenty of real-world applications can use this technology, including architecture, engineering, forensics, archaeology, mapping and video games. Becky Kagan Schott enjoys seeing wrecks come to life in a way that a single photo could never accomplish.

MY FELLOW DIVERS WERE ECSTATIC AFTER A TWILIGHT DIVE on the Okinawa wreck near Pompano, Florida, in early June 2019. I was shooting wide angle and hadn’t paid much attention to small creatures during the dive, but they had found the holy grail for macro photographers: nudibranchs — in this case, regal sea goddesses (Felimare […]
