During the past decade, photogrammetry rapidly evolved from a sophisticated skill practiced by a small group of devoted experts with appropriate equipment and special software, to a broadly available tool, which could be managed by anybody, with no restrictions regarding the educational level, professional background or virtual modelling experience.

Photogrammetry is now a common, indispensable tool, which in skilful hands can result in an excellent product in the part of the working process for which it is designed. Although technological upgrades continue to improve the hardware, software and accuracy of photogrammetric recording, the true innovation lies in avoiding overreliance on photogrammetry, but instead striving to understand its drawbacks and limitations. Simply performing photogrammetry as the end goal of an underwater excavation is not sufficient.

Considering the stated premises, the International Field Workshop Photogrammetry in Underwater Archaeological Research - Theory and Practice aims at introducing the participants to the theory and practice of the photogrammetric photo and video recording, for the needs of underwater archaeological research, taking into consideration all its advantages and constraints.
