Application of Digital Restoration Techniques in the Restoration and Preservation of One of the Photographic Images from Al-Aqsa Mosque Album at the Central Library - Alexandria University

Abstract

This research aims to shed light on the preservation status of one of the photographic images from the archives of the Central Library at Alexandria University, focusing on its notable deteriorations and the underlying factors. The study encompasses a comprehensive restoration and preservation process, beginning with digital restoration techniques, thorough documentation, and mechanical dry cleaning methods. Further steps involve wet and chemical cleaning processes, followed by the meticulous separation of the image from its secondary support, reinforcement, and treatment procedures, as well as the meticulous completion of any missing components and color retouching. Finally, the paper explores various preservation methodologies tailored to the specific characteristics of the photographic image under scrutiny. Preliminary investigations reveal the significant impact of the coastal environment on the image's condition, with relative humidity emerging as a pivotal factor in the degradation of its layers. Notably, employing a 3% concentration of calcium hydroxide nanoparticle solution alongside Klucel G reinforcement at a 4% concentration proves most effective in addressing acidity issues within the photographic image under study.
