This study is one of the few investigations which analyze albumen prints, perhaps the most important photographic heritage of the late 19th and early 20th centuries. The chemical composition of photographic samples was assessed using Fourier-transform infrared spectroscopy and X-ray fluorescence. These two non-invasive techniques revealed the complex nature of albumen prints, which are composed of a mixture of proteins, cellulose and salts. Microbial sampling was performed using cellulose nitrate membranes which also permitted the trapped microflora to be observed with a scanning electron microscope. Microbial analysis was performed using the combination of culture-dependent (cultivation in different media, including one 3% NaCl) and culture-independent (bacterial and fungal cloning and sequencing) approaches. The isolated microorganisms were screened for their lipolytic, proteolytic, cellulolytic, catalase and peroxidase activities. The combination of the culture-dependent and -independent techniques together with enzymatic assays revealed a substantial microbial diversity with several deteriogen microorganisms from the genera Bacillus, Kocuria, Streptomyces and Geobacillus and the fungal strains Acrostalagmus luteoalbus, Bjerkandera adusta, Pleurotus pulmonarius and Trichothecium roseum.

“…Como se evidencia en estos materiales, se constata que las zonas de altas luces o densidad mínima -Dmin-están representadas por picos de menor intensidad, ya que presentan notablemente una menor cantidad de Ag que las de máxima densidad -Dmax-. Esto es debido a que la plata se acumula y fija en las zonas más expuestas -las sombras-al igual que el resto de materiales formadores de la imagen [15][16][17]. En esta interpretación cualitativa también se hallaron metales como Au y otros componentes como S, Ca, Fe, Cu, Zn, Pb, Ba, Mn.…”

“…Desde su corta historia, los estudios más relevantes acerca de las copias fotográficas a la albúmina fueron los desarrollados a finales de 1980 por James Reilly [6,[10][11], a través del George Eastman Museum y el Image Permanence Institute, y en la década de 1990 por Messier y Vitale [12][13]. Actualmente, existen investigaciones importantes desde instituciones norteamericanas como el Getty Conservation Institute, de la mano de científicos como Stulik y Kaplan que han aportado a las investigaciones espectros de referencia sobre la composición de estos materiales y su datación estimada [7,[14][15] y otros estudios más recientes de autores que han aplicado diferentes técnicas analíticas para la caracterización y el diagnóstico en albúminas de colecciones patrimoniales [16][17][18][19], obteniendo resultados prometedores y desarrollando metodologías eficaces para la identificación de capas y componentes [20][21].…”

The present investigation gathers the results of the characterization and scientific analysis of a memories album with albumen prints from the end of the 19th century, belonging to the art collector Calouste Sarkis Gulbenkian. The study has focused on different analytical techniques, such as optical microscopy (OM), energy dispersive X-ray micro-fluorescence (ED-XRF), Fourier transform infrared spectroscopy with attenuated total reflectance (ATR-FTIR), Raman microspectroscopy (μ-Raman) and Fourier transform infrared microspectroscopy (μ-FTIR). The use of these different and complementary techniques allowed us to collect important information about this album, namely some organic and inorganic components present in the photographic prints and its conservation condition, data about its manufacture and to make an approximation to its historical dating.

“…In some cases, it has been used in order to identify the photographic process present in a specific number of samples belonging to a historical collection, with or without binder, as platinum prints or gum dichromates . In some others, it has been used in order to characterize the physico‐chemical changes in the original structure due to the natural or induced deterioration of the intrinsic compounds with a conservative purpose …”

Focusing in the photographic archive of Julián Carrillo (México), a microstructural analysis of surface photography was carried on to prove the feasibility of atomic force microscopy to identify the binder used in the manufactured ancient photography. It has been identified 2 structural groups in which known binders may be classified, one of them is associated with gelatin and the other one to albumen and collodion. The former group present a higher roughness values than the second one, being able to identify the binder by means of its morphology aspect related with the width of linear traces. From the obtained results, it has been observed that atomic force microscopy is a very good technique to properly identify the binder used in a photograph according to the surface morphology and roughness values.
