The Bergen Museum of Art has an astonishing collection of Edvard Munch paintings. It is the third Munch’s largest collection in the world and boasts Munch’s main works. Though, I enjoy their collection especially for their Munch’s early paintings.
For this museum I did multispectral imaging documentation of 43 paintings and 6 prints of Edvard Munch..
“The Death Bed” (1895) imaging documentation, loaded on IIP server is visible here.
Munch’s paintings have been subject recently to technical art examination, especially from Biljana Topolova-Casadiego, conservator at the Munch Museet in Oslo.

 “Hyperspectral image capture and analysis of The Scream painted by Edvard Munch in 1893″. The Norwegian Colour and Visual Computing Laboratory, Gjøvik University College, Gjøvik, Norway, is applying hyperspectral imaging on The Scream (1893).
This group is holding the “Colour and Visual Computing Symposium 2013″ in Gjøvik, Norway. http://www.colourlab.no/cvcs/ If you are interested, the submission deadline is in 2 weeks.
 Biljana Topalova-Casadiego, ‘Technical Aspects of Edvard Munch’s Painting’, in Edvard Munch, The Complete Paintings, G. Woll (ed.), London: Thames and Hudson (2009). I didn’t read this resource yet, though, Jilleen Nadolny, who worked on its translation from the Norwegian, with Katja Stieglitz, strongly recommended it as one of the most complete discussion on Munch’s technique.
