Removing Shadows from Images of Stained Glass Windows

摘要

Shadows may be formed on stained glass windows by structural bars supporting the leaded panels, or by external protective wire grilles, or by masonry such as mullions or buttresses, or external objects such as trees. The eye tends to 'discount' such shadow formations when viewing the actual windows even though in the photographic images they are very clearly visible. Digital modelling techniques enable the shadows to be characterised and removed with a reasonable degree of success.
