Underwater reflectance transformation imaging: a technology for in situ underwater cultural heritage object-level recording.DavidSelmoauthorFraserSturtauthorJamesMilesauthorPhilipBasfordauthorTomMalzbenderauthorKirkMartinezauthorCharlieThompsonauthorGraemeEarlauthorGeorgeBevanauthor"There is an increasing demand for high-resolution recording of in situ underwater cultural heritage. Reflectance transformation imaging (RTI) has a proven track record in terrestrial contexts for acquiring high-resolution diagnostic data at small scales. The research presented here documents the first adaptation of RTI protocols to the subaquatic environment, with a scuba-deployable method designed around affordable off-the-shelf technologies.[...]URTI is shown to be capable of providing analytically useful object-level detail in conditions that would render ordinary underwater photography of limited use."
