“…Furthermore, the behavior of baryta peaks for different angles of incidence permits (1) its unambiguous distinction from e.g., the cellulose of the support, whose absorption bands may coincide with and even overcome those of baryta in FTIR-ATR as observed in other reports (Ricci, Bloxham, and Kazarian 2007;Vila and Centeno 2013;Cattaneo et al 2008) and (2), subsequently, an estimation of its depth in the photographic structure.…”

Focusing on the photographic archive of Julián Carrillo (México), we study and characterize the photographic process of a set of 13 photographs dated between 1884 and 1925. By using infrared spectroscopic ellipsometry we classified a selected set of photographs according to the kind of binder used. Thus, we recognized for each photograph, the presence of proteins, and thus the particular photographic process. Furthermore, we have identified the presence of baryta layer, the use of plasticizer, and the eventual coating utilized to protect the photograph, whose composition was based in natural organic components, mainly shellac, beeswax, or camphor.

“…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. [14][15][16] 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. [17][18][19][20] However, they present certain limitations in the identification of some compounds with similar molecular structure, so complementary measurements are typically required through other techniques.…”

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.

“…The instrument is handheld, meaning that in-situ analysis are possible, which requires little or no sample preparation or modification. X-ray penetration depends on the material, but it's not much than a few microns, which makes this method ideal for pigment analysis [31,32].…”
