Infrared Reflectography: InGaAs camera VERSUS Digital Camera


This post compares an InGaAs camera - used for Infrared Reflectography (IRR) with a Digital camera modified for Infrared photography (IR). An InGaAs camera is your choice when it comes to imaging underdrawings. Though, the advantages of the InGaAs camera, even if real,  are limited. So, we should be aware of them before we decide [...]

Raman spectroscopy for Art. Instruments


I started working on cultural heritage science with a bench-top Horiba Jobin Yvon Raman Spectrometer  in 1999. I did keep working on other Raman systems from time to time. A lot has been written on this technique  and its applications for Art and Archaeology.So, this post just provides - as usual - my personal insights. [...]

Volcanic Eruptions. Infrared Photography


I took this image from my Lab, a couple of weeks ago. I live close to Mount Etna, the tallest active volcano in Europe, about 3,300 m high. Etna is in an almost constant state of activity and we are kind of used to those smoke plumes. http://youtu.be/j3ZbaWn_yg8 April 2013. Etna eruption seen from [...]

Mobile Nuclear Magnetic Resonance for Art. Workshop in Volterra


Volterra, Italy, will host the workshop “Analyzing Cultural Heritage using Portable Magnetic Resonance”, 12-15 June 2013. There are some scientists in Europe and US studying the applications for art conservation and historical architecture of mobile Nuclear Magnetic Resonance (NMR) systems. Among them the Pratt Institute where last year I taught “Scientific Art Examination”. [...]

Multispectral Image Analysis for Art. MultiSpec


This post introduces MultiSpec,the Multispectral Image Data Analysis software that I use. It’s free and pretty easy to use. On their website you’ll find tutorials and examples to learn and master it, so, I’ll just give here a very simple example of its application for examination of art. Just to let you see how neat [...]
