RTI at the Cataraqui Cemetery March 20, 2010


An overcast day – the perfect conditions for Reflectance Transformation Imaging acquisition. Nine students joined us from 1 to 6 pm to image 9 stones. The students were divided into two groups and produced some of the best RTIs to date. We imaged two limestone and seven marble head stones.

Here are some screen shots and comparison images:

one of the oldest stones / local limestone / regular light / specular enhancement

the bio growth and rain drops obscure some of the surface information

practically illegible stone of Philip Ferguson Hall / regular light / specular enhancement

marble insert into sandstone / Ann Jane Brown / Regular Light / Specular Enhancement
