RTI stands for Reflectance Trasformation Imaging.

RTI at the Urban Variation Conference, Gothenburg

Last week Gareth and I travelled to Gothenburg in Sweden to present at the Urban Variation conference.  The conference website is here: http://conference.earlymoderntown.com/urban-variation/.  The conference was organised by the Early Modern Town Project team (find the University of Gothenburg project website, here; http://www.earlymoderntown.com/) and was attended by a multidisciplinary crowd of academics and professionals.

AHRC RTI project

The AHRC have awarded Follow on Funding to build on the RTISAD project. This grant will explore the possibilities of digital imaging in ancient document research, in archaeology, in industrial applications such as textile design, and in other contexts. The underlying technology called Reflectance Transformation Imaging (RTI) uses multiple images to produce an interactive representation of subtle surface details such as brush strokes on paintings.

Winchester Cathedral RTI Community Day

On the 1st February I hosted a community RTI (Reflectance transformation imaging) day at Winchester Cathedral. The day was based around the introduction of this useful technique to the Cathedral guides, the Master students based in the computing research group and the lifelong learning students that have taken recent evening classes at the University.

How to fix incorrectly aligned RTI images

Often, when capturing a RTI data set, especially when using a cable, the images captured can be out of place, resulting in an incomplete data set. The following is a how to guide to fix this problem using Photoshop. The first step is to load all of the files into Photoshop using the correct tool. This is done by clicking the file tab, then Scripts and then "Load files into Stack". Continue reading →

The oldest erotic image in Estonia?

As one of the Estonian newspaper stated, it could be the oldest erotic image found in Estonia. It is an engraving on the wall of the old church in Lüllemäe. To get a better "reading" of the image we used RTI technique to document it. Here are some example screenshots below, interactive image can be viewed from Archaeovision's website. Continue reading →

AHRC RTISAD project legacy – 18 months

Another six months have passed, and we have been as busy as ever using the RTISAD equipment and expertise. Dissemination In October Nicole Beale demonstrated Highlight Reflectance Transformation Imaging (RTI) at the Insight from Innovation conference, a three day archaeological ceramics event hosted by the Ceramics Research Group. More details on this blog post. Continue reading →

RTI & Numismatics Conservation

RTI is considered to be a powerful documentation tool for cultural heritage applications. Previous work in the field of RTI in numismatic studies demonstrated advantages in identification and documentation issues in comparison to traditional approaches, as well as improved communication and dissemination abilities (Mudge et al. 2005; Gabov and Bevan 2011).

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 →

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.
