In October 2017, Factum Foundation's Otto Lowe and Pedro Miró recorded the marble Trophy Wall decorating the façade of St. Mark´s Basilica in Venice. They conducted high-resolution photogrammetry and composite colour photography of different panels.
The marbles add a symbolic layer of meaning to the facade of St Mark Basilica. The slabs, formed with materials taken from Constantinople, were positioned to draw attention and significance to their location. Each colour carried political or liturgical connotations that visitors could recognize within the interior and the exterior of the space. For instance, green, black and white marbles, used to cover slabs and column shafts of the facade were traditionally associated with imperial sarcophagi.
Processing the data
This complex surface was digitized with photogrammetry as part of a research project about the aesthetics of marble. More than five thousand photographs were taken of the two walls.
The images were processed using Capturing Reality software to focus on the relief with and without the colour information. The samples below offer both sets of information.
