The ACCORD team worked with the Rhynie Woman group based in Rhynie and Huntly, Aberdeenshire from the 29th to the 31st of August 2014. Together we modelled and recorded a standing stone with Pictish symbols known as the 'Craw Stane', another Pictish symbol stone in the town square and two headstones in the Rhynie churchyard, one 18th Century and the other 19th Century. We used the techniques of Reflectance Transformation Imaging (RTI) and photogrammetry.
The Rhynie Woman group are the formalisation of a community of interest that emerged around archaeological excavations (The REAP - Rhynie Environs Archaeological Project led by Dr Gordon Noble at the University of Aberdeen, in collaboration with Dr Meggen Gondek at the University of Chester) taking place in their locality, and a shared passion for art and creative practices. As a named group, the Rhynie Woman are only one year old, and are currently writing a constitution and seeking official status as a Charity. Ten members of the Rhynie Woman took part in this ACCORD project. Their logo is the outline of the famous Pictish carving from the local area known as the Rhynie man, and they maintain an active Facebook page.
For photogrammetry, data collection consisted of digital images captured with an 18-55mm Nikkor lens on a Nikon D5300 DSLR camera. Before any images were taken, the camera and lens settings were set to automatic with no flash and images captured at JPG fine quality (metadata for each image is provided in the accompanying excel spreadsheet). A total of 188 digital images were captured in order to create a photogrammetric model of the Pictish 'Craw Stane'.
For reflectance transformation imaging, in all cases, data collection consisted of digital images captured with an 18-55mm Nikkor lens on a Nikon D5300 DSLR camera. Before any images were taken, the camera and lens settings were fixed so that each image was taken within controlled parameters, with no flash and images captured at JPG fine quality. We used the RTI builder software available from Cultural Heritage Imaging, which uses a polynomial texture mapping plugin. We used an LED hand-held light source for highlight based data capture, and a shiny black sphere mounted on a tripod next to the object surface. To minimise light pollution data capture took place under a tarp. In total we took 40 images of the 'Craw Stane', 50 images of the Pictish stone in the village square, 70 images of the headstone dedicated to Alexander MacKay, and 57 of an elaborate 18th Century headstone.
