International Academic Projects: Technical Imaging of Paintings (and other cultural heritage objects)

Examining traditional imaging methods and others.

Tutor: Nathan Daly

This seminar will focus primarily on paintings, (other objects will be mentioned when discussing the benefits/limitations of different techniques) and  will examine traditional imaging methods (visible imaging, ultraviolet, infrared reflectography and X-radiography), other imaging methods (3D imaging, RTI, Optical Coherence Tomography, Terahertz imaging), Spectroscopic imaging/scanning methods (MA-XRF scanning, Hyperspectral imaging/reflectance imaging spectroscopy, MA-XRD scanning; Microscale scanning – Raman, FTIR, etc.).

Case studies will illustrate the application of some of the techniques and mention will also be made of:  the identification of the proper technique to use; mosaicking and registration; the size of datasets and ease of processing and interpretation; complexity/convolution of observed signal/images.

There will be a 55 minute presentation followed by 15 minutes of discussion.

Nathan Daly received a PhD in chemistry from Columbia University and recently joined the Scientific Department of the National Gallery as a postdoctoral fellow funded by an UKRI research grant with University College London and Imperial College London. In this role he specializes in the acquisition of MA-XRF and hyperspectral data of both reference materials and paintings in the National Gallery collection and their subsequent preprocessing and analysis.
