FINGERPRINT: the toolbox

infrastructuur-fingerprint00021-1In a previous blogpost, we introduced the FINGERPRINT project. FINGERPRINT is an interdisciplinary collection and data management project on the exceptional collection of graphic works by Pieter Bruegel the Elder (ca. 1520-1569). It involves the collection and processing of a large amount of visual and material data. To obtain that visual data we have an extensive toolbox at our disposal: a high resolution medium format digital back, a motorized repro stand, a Nikon DSLR modified for multispectral imaging with a collection of multispectral filters, the RICH microdomes and much more. A brief overview. Continue reading

Digitizing a porcelain card – in pursuit of a faithful reproduction

porseleinkaart_mo_03

The KU Leuven University Archives requested a digital reproduction of a porcelain card. A porcelain card is a 19th century lithographic printing technique that uses either white lead or kaolin to produce prints with a very distinct shimmer (more information here). Because this shimmer is an essential aspect of the porcelain card, we somehow had to preserve some of the shine in our reproduction. 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.
