Didactic Panel Illustrating Light Exposure Effects
-
Sarah Simon
Abstract
A small framed display panel holds a selection of paper and media common in works on paper plus a set of Blue Wool Standards. The selection of materials and design of the panel including two types of glazing are presented, and the purpose of the panel as a tool for explaining the effects of light on materials is discussed. At the centre of the panel are watercolour samples prepared using primary colours in mixed washes that illustrate hue shift resulting from selective fading of one colourant.
Zusammenfassung
Eine kleine gerahmte Schautafel enthält eine Auswahl unterschiedlicher Papiere und Zeichen- bzw. Malmedien, die bei Werken auf Papier üblich sind, sowie Blauwollstandards als Lichtechtheitsmaßstab. Der Beitrag stellt die Auswahl der Materialien und die Gestaltung der Schautafel vor und erörtert deren Zweck als Instrument zur Erklärung der Auswirkungen von Licht auf verschiedene Materialien. Im Zentrum der Tafel befinden sich Aquarelle, für die Primärfarben unterschiedlich gemischt wurden, um die Verschiebung der Farbwirkung durch selektives Verblassen eines einzelnen Farbmittels zu veranschaulichen.
Acknowledgments
The institution’s friends’ group (Kulturdenkmal Galerie Fähnle n.d.) enabled the conservation of the Hans Fähnle collection with the support of the Wüstenrot-Stiftung, which has generously contributed funds. We are particularly indebted to Volker Caesar who has been instrumental in implementing the project. Former students Hannah Wachter and Jennifer Adami contributed to the selection of materials and the design of the panel.
