Since common digitization techniques are obviously tailored to minimize the amount of reflection, this turned out to be quite a challenge. Continue reading

iQ-Analyzer report, ColorChecker SG – own measurements

In a previous post we discussed the use of the X-Rite ColorChecker SG card and the online platform delt.ae as a means to control and validate the colour accuracy of our digitisation workflows. Whilst that process allows for a quick colour management, we found it to be somewhat insufficient in those cases where we want to take the quality of our captures to the next level.

Magister Dixit: KU Leuven and UCL collections completed

Magister Dixit projectThe Imaging Lab recently completed the digitisation of 301 manuscripts with lecture notes of the ancient University of Louvain. Digitisation took place as part of the Magister Dixit project, for Lectio, and with support of the InBev-Baillet Latour Fund. Lecture notes have naturally been scattered all over Europe but both KU Leuven and the UCL built up extensive collections after the destruction of the library during World War II in which 68 manuscripts were lost. The recently gathered collection is now virtually reunited. Continue reading
