An RTI file is a composite of multiple images of a subject photographed from a fixed position for which a light source has been repositioned at a constant radius from the subject, thus creating a hemisphere of positions. ]]></termNote><termCreatedDate>2026-03-30 20:40:14</termCreatedDate><relation><relationType>UF</relationType><termId>31371654</termId><termName>RTI</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31371655</termId><termName>imaging, reflectance transformation</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31340758</termId><termName>digital imaging</termName><termType>PT</termType></relation></term>  </Zthes>
