RTI shedding new light on Iberian Late Bronze Age stelae

During the first two weeks of September David Wheatley and myself, jointly with Leonardo García Sanjuán (University of Seville), have conducted fieldwork in Lora del Río, Seville (Spain). This fieldwork has been aimed at providing enhanced contextual data and visual recording of a Late Bronze Age decorated stela. As part of this work we have applied Reflectance Transformation Imaging (RTI) and the results are really amazing. RTI allows us to examine the surface of the stela interactively. Continue reading →

Photographing Portus

Photography has been extremely important to the Portus Project. The photographic record which has been created as we have been working on the site allows us to re-visit and interpret the excavations at many levels. As well as a vast archive of photographs depicting excavated contexts, sections and objects we also have a substantial collection of images which depict the day to day life of an archaeological excavation.

Laser Scanning at Portus

In the past week myself and Gareth Beale have spent time capturing the subterranean areas of  the Imperial Palace at Portus. We have been trialing the use of the Leica Scan Station C10 for archaeological documentation and the results so far appear very impressive. All archaeological remains are subject to constant deterioration, this is especially true of substantial architectural remains such as the Imperial Palace. Continue reading →

Demonstrating RTI for Ceramics

Yesterday I was demonstrating Highlight Reflectance Transformation Imaging (RTI) at the Insight from Innovation conference, a three day archaeological ceramics event hosted by the Ceramics Research Group, celebrating Emeritus Professor David Peacock's contribution to archaeological artefact studies. I always find these kinds of events really exciting as they are often a fantastic opportunity to discuss with experts in their field the potential for RTI within the area that they work.

Portus Project Lecture

Last night Professor Simon Keay delivered a lecture outlining the recent research he has been leading as director of the Portus Project, which explores the site of Imperial Rome's maritime port. Entitled “Roman Emperors, Ships and Commerce: inter-disciplinary research at Portus 2011-2012?, the lecture was chaired by Professor Don Nutbeam, Vice-Chancellor of the University of Southampton, and introduced by Professor Anne Curry, Dean of the Faculty of Humanities.

Infrared RTI

Last night i took the artwork from my wall and did my first infrared RTI. I would say it is even more exiting than normal RTI as you will see things you are not able to see with naked eye. Artwork I was taking photos of was not maybe the best to show the potential of IR RTI but I hope to try it it again with bigger light-source (I used converted Maglite Mini) and more challenging art-piece. Click on image to switch in between normal photo and IR RTI with specular enhancement filter. Continue reading →

GigaPan work at Bodiam Castle

Between the 4th and the 24th August I spent some time at Bodiam Castle and the surrounding area completing a geophysical and building survey of the castle and grounds. The work is a collaboration between North Western University, Chicago, USA (Prof Matthew Johnson) and Southampton (Kris Strutt) and has been used as a teaching aid to first, second and third years. I have spent three years working at this wonderful site and I have never taken a single photograph of the castle. Continue reading →

ACRG Collaboration with the Department of Classics, Cambridge

I have recently completed some work with Dr Rebecca Flemming in the hope of a future collaboration between ACRG and the department of Classics at the University of Cambridge. The work that I have completed relates to the laser scanning of Roman anatomical votive terracottas. The work is in its early stages but I have included some images of the three dimensional models that I have created from the recent laser scan work on objects that are similar in shape and size.

Recent RTI work at the National Archives, Kew

Myself and Peter Wheeler spent a week working at the National Archives recording a number of different items using RTI. The work was a continuation of the DEDEFI project that Hembo Pagi completed in 2011. The majority of the work was from the 19th century Records of the Patent Office books specifically looking at Patents, Designs and Trade Marks Office and predecessor. In total we recorded 56 RTIs over the space of the week and we had time to also record a few Medieval seals for Adrian Ailes. Continue reading →

Multispectral world

Last weekend I spend some time with ACRG multispectral camera (converted Nikon D700). I got Hoya R72 infrared filter and walked on the fields of Western Estonia. I am very happy with results (see below). When it became dark outside I took the soldering iron and made two-led IR torch. This will be used for RTI testing later this week. One thing I found out already, you need quite long exposure time for a sharp image or/and much brighter light source. Continue reading →
