After the course last year at Open Source in Milan on non-invasive analysis and imaging for art works (Non Invasive Diagnostics For Paintings), I have been researching further into the subject in order to be able to make more use of these methods in my work.  Currently I am currently working towards a project with colleagues in the field which will seek to use these methods for a complete imaging survey leading to a later conservation project.

Non-invasive methods of analysis are ethically preferable, where technology allows, over traditional sampling, and are already mandatory in many situations.  This is particularly relevant to projects in Egypt where traditional sampling for pigment analysis or layer structure can only be undertaken in very specific and exceptional circumstances with specific permissions.  For this reason further understanding and research into these methods is very relevant to me, as are any tools and ideas to facilitate it.  This most recent tool from Cultural Heritage Science Open source, who already produce a multi-spectral imaging system for painting analysis which is non-invasive, low cost and designed to be affordable to conservators across the field (see more about their work here: Pigments Checker), have just produced this very useful tool which demonstrates how to use the technical photographs produced through imaging in Photoshop:
